extUSB Data Cable? Not needed anymore!!!

Last night when I was half a sleep I plugged into my HTCTouch Pro a standard USB cable in its ext USB port. It started charging and I went to bed. When woke up in the morning, I was shocked and I was a fraid some thing could have happened to the devive. I immediately unplugged it.
I checked the device and there was nothing wrong with it. I decided to test it further. So, I connected the "wrong cable" again and I could exchange files normally with this standard USB cable. I also used for active sync and Internet sharing!
I also connected the standard cable the Pro's charger and it worked like a breeze. This means that if you need an additional USB cable you can buy a cable at quarter the price of the damned "extUSB" one!
Hope I provided you with some useful trick.
Note: Use it at your own risk. But I tested it on my device with no problems. Perfect!

Sorry to ruin your excitement, but pretty much everyone knew this already. The ExtUSB is a standard USB plug but with extra pins on the edges that only ExtUSB cables have receptors for. They are just audio and video pins, and aren't required to charge to transfer data.

LMAO!!

Third, actually, and my post didn't even seem to surprise anyone: http://forum.xda-developers.com/showthread.php?t=444534
However, with a huge and complex forum like this, it's no wonder and no shame that things get discovered, asked or explained again and again. I'm sure there's a lot of people that didn't know this yet and found out by reading your post. So kudos to you.

First time I've seen it. Good to know for when I get mine in a week or so!

was it ever necasarry?
i used regular mini usb on my 8525 all the time

You guys got to be kidding... I couldn't even imagine that someone doesn't know about this already. Mini USB is the standard charger for most recent device these days.
I use the same mini USB (got it for $3) to charge my phone, my camera, my MP3 player and anything that I can plug in. A USB port from your computer have an output of 5Volt... so don't worry about it, it won't kill your device.
Welcome to the Forum, by the way

guys - give him the credit for his discovery. at least it helped me - i didnt know and to me he is the best inventor of 2008!!!!! Way to go abdelbaset0

Lol, this stuff gives me the giggles, personally, ive always used normal MiniUSB cables, ever since they brought out that connection on their devices, but the really funny thing is, when i was in a T-Mobile store once, the attendant genuinly thought it would damaged the device when i said i wanted a normal (miniUSB) car charger to use with my TyTN.... Still Chuckling now.

Sadly, because of reps like that, the various print materials, websites trying to overcharge for a product, and the general user's fear and lack of education....this is the sort of information that a lot of people will probably find to be wildly helpful, even profound.
When my girlfriend got some phone, not entirely sure which one (she's been through quite a few), she thought she had no choice but to use the charging brick and data cable that came in the box. She complained about a low battery one day while in my car. A quick look to see the shape of the port and I plugged in my car charger. She was in shock...and I was equally shocked that a very computer literate asian girl would feel comfortable installing windows but was baffled by the shape of a plug

Smartcable - keychain microUSB cable + microSD reader

Just got one of these smartcables from ebay for £4.99. Thought I would give you guys a quick review, because I think these are pretty cool. I saw a thread here where people claimed they did not work as sync cables, and only charged. I can confirm that my cable WORKS FOR DATA TRANSFER ON THE DESIRE.
This thing is great - the metal barrel unscrews to reveal an USB plug and a microUSB plug connected by about 7cm of cable. The tip of the USB plug itself is hollow and allows a microSD(HC) card to be inserted and read. The barrel is 16mm in diameter and about 3.5cm long, plus the loop of cable. Might be a bit too big a keychain for some of you - I don't mind as I carry a whole jumble of stuff anyways.
There is a tiny slide switch just above the USB plug which switches between connecting to the phone or the integrated microSD card reader - the computer can only see one at a time. While the switch is set to microSD, the phone can still charge. I think the people who couldn't get these to transmit data either didn't discover this switch or had defective cables. The switch really isn't obvious and requires something pointy to toggle (I find the end of a key just about works).
There are two LEDs - a red one which lights up whenever there is a USB connection and a blue one which indicates the SD card reader is active.
I would recommend these to anyone wanting a portable cable, either for sync of for topping up the battery. Coupled with a microSD card, this acts as a perfectly decent flash drive.

Yeah, I bought one because of that thread. Mine definitely syncs, you should get yours replaced.

I got one also, after the original post. Syncs just fine if the tiny switch is in the correct position.

what does thing actually do?
it charges and synces same time? what about synching and using as disk at same time?

It has a switch which can toggle between two modes:
- Charge and sync phone like any USB cable
OR
- Charge mobile and act as a microSD card reader

The seller just said me that it doesn't work for HTC Desire...

Yeah, the seller insisted that these only work on Nokia phones with a "5 PIN" connector when I asked him. Google reveals that these phones just use a standard micro-USB port. The cable arrived with a "For Nokia, Samsung, Sony Ericsson" sticker. Again, mine works fine - the seller probably can't test this and would rather lose sales than have people complaining when stuff doesn't work.

so using it as disk and syncing same time isnt possible?

Nope, you need to unplug the cable and toggle the tiny switch.

The switch is just a physical toggle on the data pin switching between the device connected to the cable and the data pin of the card reader in the head of the USB plug.
Switch it one way, one has data, switch it the other, the other does.
Keep it in the middle (astable) then either both or non do and you get a lovely mess

So it should work, right?

I have one of these sitting in front of me.
Yes I can sync data with my desire, yes I can charge and (with a flick of the switch) I yes I can read a sd card however that last function is not important to me.
But for some reason, this is bigger than I expected it to be,

Mine works for data as well, as already mentioned its just a shame they couldn't have made it a bit smaller.

This looks like just what I have been after. I can only see them for £12.99 (not the £4.99 the link has and that seller has only SE and the wrong type of Nokia) on ebay. Before I place an order as it still seems worth it, does anyone know another place to buy from? Thanks.

Don't buy one for £13, wait until the seller updates their listings with more of the £5 ones.

The switch on this is insane it is almost completely hidden, it doesn't even poke out or anything.

Yes, but in general use you don't need the switch.
It's only there if you want to plug a micro-sd card directly into the USB connector.
If, like me, you just want it to charge/access your Desire, you can leave the switch in the other position.
Regards,
Dave

Well I never! I've had this cable for about 2months now and not even realised there was a switch there! J changed it over last night and it didn't really work, 'connection failed' type thing came up on the pc, but the phone recognises the pc is there, so maybe I was just unlucky. Would highly recommend this cable..

USB OTG killed my S3

I'm just posting for brief warning/general info for you guys. When I got to work tonight I plugged in my USB OTG cable which I have been using w/ no issues on both my N7 and S3 since July and then plugged in a 64gb flash drive that I have also been using since launch. When I plugged in the flash drive, I heard a pop, the screen went blank and the phone is totally dead. A quick search showed while this isn't incredibly common, it has happened to several people. Most blamed the OTG cable, but I disceted mine and it had no broken wires and no shorts. I turned up a thread on root wikiz that basically said that it is the power management IC self destructing and there is nothing that can be done to repair it. So, just a heads up if you use OTG-- I am not sure I will use it again on this phone as it seems it is just a matter of time...

Jason

This happened to me. Verizon will warranty the phone. I wondered what actually blew up in the hardware. I am surprised it hasn't happen to more people, seeing how you really don't have any control over whether it blows up or not.

Sorry to here about your phone. I was jut about to go buy one of these cables.
This same thing happened to my phone a few weeks ago. It went totally dead out of nowhere, I was taking photos at the time.
You shouldn't have a problem getting a replacement even if you don't have insurance.
Good Luck

I have heard stories about that happening, though its not common, it is surprising that its so low considering its random and no one knows exactly what causes it

at least you don't have to factory restore before returning

Sorry guys, I just woke up. Was on graveyard shift last night. Anyhow, the cable was a generic ebay right angle otg cable, about 5" or so in length. I am 99% certain it had nothing to do with the cable though, just a hardware problem. As mentioned above I dissected the cable and it had no problems. I could still use it on my Nexus 7 with no issues. I had the cable plugged in before inserting the flash drive and it was fine until the flash drive was plugged it.
The Root Wikiz thread I mentioned said that someone had sent theirs in to be Jtag'ed thinking it was just hard bricked. The response from the people where he sent it was that they had seen a number of them with the PMIC damaged and that there was nothing that their services could do for them.
My guess is there are some marginal PMIC's out there and that when they switch the port from charge to host mode they just cant take the current and pop. The fact that I made it nearly 5 months using the same OTG cable on a regular basis kind of lends credence to this theory, but who knows. All I know is that it was totally dead, absolutely no signs of life regardless of what I tried.
FWIW I was rooted and running paranoid android, but I have found reports of this happening to bone stock phones as well as any variation of ROM. Verizon did warranty the device. Oddly, the tech told me "I have never heard of this happening" but didn't even ask me to try anything with the phone, he just said that they would ship me a new one for warranty replacement.
New device is here, I'm off to root and unlock! Good luck guys.

Wow, that sucks, but I am glad you got another S3. I have been using this one that I got from Amazon. It has a couple of usb ports and 2 card readers. I have been very happy with it. It is extremely useful when I am at family functions, and everyone has taken a lot of pictures and video. I can grab their cards and pull the pics and video onto my 64 Gig SD card on my phone. People are amazed I can do this with my phone! However, now I am a little worried about using it. I will keep this in mind, and only use it on the occasions that I really need it. Thanks for the heads up!

my s3 discharging immediately
hi everybody....
i have an issue with my s3....i make an OTG cable and plug it into my s3...and i just can get power from it,no data.
but i think the s3 is already wasting power and i must charging it after a day.
can anybody help me!!!!!

One day charge is normal if using phone. If gonna use OTG you are overusing and can expect 1/2 day. Buy good cable if want data.

I had something similar happen except, my usb sent a static spark from my oc to my phone. Didn't fry it completely, but messed up something that would no longer dock to pc, dock to car our go into deep sleep.
Wonder if the two issues are related.
Be sure to discharge any static in you usb called before plugging them into your phone.

Discharging is what the battery always does when not plugged into A/C power and turned on, and even sometimes when it is plugged into A/C power (when you get in the top 10% of full it starts going through discharge/charge cycles to keep it within the top 10% of power but never totally full. This prevents overcharging and explosions)
That said:
A sudden reduction in the runtime for the battery under the same average load is almost always the battery going bad.
If you mean the battery doesn't last as long because you now use OTG - those things you plug into the phone need to get their power somewhere. The phone battery is it.
So now you are powering the phone + whatever other things you attach to it. Some of them can drain a lot more power then you might think. You just never noticed much (if at all before) because your total reserves weren't such a tiny amount.
If you stop using OTG devices and your battery capacity bounces right back up to where it was before, then you can reasonably infer the extra gadgets are the culprit.
(if you stop OTG stuff for a few days and the battery still sucks when before it didn't, probably need to buy a new battery because yours is most likely shot.)
Assuming it seems to work fine...
So two choices, right? No accessories and lots of battery life, or lots of accessories and no power to run them with.
well...not really:
It's probably not always possible - but how often do you use OTG near A/C power?
Whenever you are near somewhere you can plug in, the first thing you should plug into your OTG cable (besides the phone) is a USB hub with a power cord.
...and really, if you want to use those power hungry USB hard drives and things like that, then you really can't without taking the stress off of the phone of supplying that power - that hard drive just half spins up like a car that cranks but won't start.
Every crank in that car wears the battery down and beats up the starter when it doesn't fire up the engine. Just like every spin up but not quite read of the hard drive puts incredible load on the S3 to try to throw enough current at it fast enough to keep it happy. Just beating it up for nothing.
Which brought me to what I wanted to bring up for some consideration:
Think about trying to use a powered hub whenever you can as the first thing off the OTG cable, should take an immense amount of stress off of the S3 in making it all work.
Bet at the least you reduce the risk of popping since the power spikes will be much less - that powered hub is a pretty solid buffer for that kind of stuff when you are constantly popping flash drives in and out.
I remember way back when for the Nook Color when some really sharp people made OTG happen out of the thin air - no way Barnes & Noble had that on even a remote list of possibilities when they were ready to throw the device to the masses and see what happened.
If you wanted to use more then the smallest of thumb drives you needed a powered hub. The device wasn't designed for it, and simply wasn't able to squeeze more then a paltry amount of power out in reverse. (but it was just enough to talk to a powered hub...)
Anywhere that you can plug in your powered buffer should contribute to avoiding the problem the OP posted about. The thought experiment (hopefully) growing from this post? How much truth does this theory exhibit?
Edit: Totally missed this post:

Here you say you made an OTG cable, the first post I quoted you in you said you bought one. If you made it, i'd say that is your problem.
The quality of the cable you use absolutely matters. Higher quality parts = higher quality results.
I have a bunch of micro USB cables (as i'm sure many of you do also - ) ... and from some of them I get an absolute night/day result in charging.
Some cables (mostly the ones from the dollar store or older cables) just plain suck. They can't bring enough power from the same A/C adapter as my OEM HTC/Samsung cables. (I have some motorolla OEM cables from around the time of the droid X launch - they are closer to the dollar store cables in quality - haven't tried recent motorolla OEm cables, hopefully they got better or I got a bad batch over a six month period)
Using the low quality cables I can absolutely lose power plugged in just being a wifi hotspot with the screen on, until it eventually goes critical and dies. (this I tend to notice when my pc banished to the corner of nowhere loses all network connectivity) - whereas with the HTC/Samsung cables from within the last two years keep me near full with that being the only difference.
I'd rather have a few good cables then a bag full of POS dollar store ones. That little bit better material, little bit tighter QC adds up to a big difference in the final outcome.

This same thing happened to me when I plugged the same type of cheap right elbow OTG cable from ebay into my brand new S3 (2 days old with about one hour of usage). The cable worked fine with USB drives, a mouse, or a keyboard used alone on the S3. The cable was plugged into a USB 4 port hub with multi-card reader. The screen was off when I plugged it in so it appeared to just be off. Any attempts to power it on were fruitless. I smelt the phone right afterward and there wasn't any burnt smell. Plugging in the phone resulted in it getting pretty warm but not to an extreme yet the battery remained cool. It appears to have burnt something between the battery and lines but leaving the components intact thus causing the excess of heat. BTW the hub/reader is fine. I won't be using that again on my new one but I will be attempting to use a different hub that has been working fine on my wife's RAZR MAXX HD. Just hope this is a very isolated incident and not a bad batch from the retailer.
Edit: The S3 is a blue 16G Verizon model. The S3 was on stock ROM when this happened (not like that would prevent death from inferior circuit protection components).

Were you using a powered hub, or passive hub?
Anyone tried a DAC off the OTG cable?

Don't do it. I've fried 2 GS3s with a UCA-220 DAC over otg.
First time with a regular OTG cable, the second time with a OTG/phone charging cable, the power came unplugged and zap. I'm lucky Verizon has replaced the phone two times.
I think the best solution is to completely isolate the DAC power from the phone power. A circuit to charge the phone with the otg/charge cable and a separate circuit to power the DAC.

Wouldn't use of a powered usb hub remove any power issues? I purchased a OTG cable today.. I had planned to connect it to a powered hub, and run the DAC off that?

Charging stand with storage switch

Hi all,
Have just bought a stand for my HTC m9, it's a sleek looking bit of kit and only costs a tenner which is pretty cheap.
It is designed to work with the phone with no case although there is a removable part which allows the usage of the dot matrix case too, I've confirmed that this works too.
Chances are you may be able to fit some other cases in there but they would have to be slim, the Spigen hybrid does not fit unfortunately, possible to do some modding but that would be down to you.
You can connect this up to your laptop /PC ( USB 3 charges pretty good compared to usb2) it allows you to mount storage via the dock, also confirmed, a standard USB socket is also present on the back which can be used for OTA purposes, keyboard, mouse, gamepads, hard drive etc (untested but should work).
The design is sleek and sturdy, it holds the phone up well, could maybe use a little more weight.
Personally I got it for work so I can mount it and maybe use it as a clock, see messages via the dot matrix case, play music (can change tracks from the matrix case) so far it's working as expected.
Would recommend.
£9.95p amazon UK. Quick delivery, 3 days, no charge.
Edit: @ mod, like a massive melon I've posted this in the wrong thread, can this be moved to accessories please. My apologies, haven't had much sleep,

Yeah, I got one of those too, only to discover that it kills quick charge for some reason. Would not get above 150mA no matter what charger I used.

Don't say that i was beginning to like this, will have a tinker.

Actually, I'm getting a normal charge from mine. I don't like fast charge, it damages the battery. So id rather not do that. Normal charging for me. Just under two hours.

Have just noticed something. Whilst plugged into a charger, this device does not allow USB OTG? What is the point of that? If you disconnect the charger then it works very well but not whilst connected, have not tried whilst connected to a computer / laptop.

Sure the switch on the back is in the right position? I'll admit I haven't played with mine much.

Have tried both, like i said without the cable connected it works fine, selecting it away from OTG, does switch connectivity off, however connecting a cable whether on OTG or USB de-activates it.
I know this isn't an official dock so support is going to be really limited.
Might take it apart and see how it's patched, the power source is more than likely for mounting the phone onto a computer, hence the disconnection.

Xperia XZ Premium Charging Issues

Hi All,
I'm hoping someone here can share their opinions.
Recently I've been having charging issues with my XZ Premium. Started a few weeks ago, with the charger plugged in, it would randomly stop and start charging.
Lately it's been getting much worse. I have tried different chargers, cables, adapters etc. The original Sony USB cable plugged into a wall charger, and my laptop. My Dell laptop USB-C (thunderbolt) wall charger, as well as my Dell external battery charger, as well as MicroUSB cables with a USB-C adapter.
Without touching the cables or moving anything, sometimes it'll start or stop charging randomly.
I personally think it's the phone's USB-C connector. I've tried to clean it using a damp wooden toothpick and got some dust out, but it didn't make any difference.
The phone is rooted, and is out of warranty anyways. I also have a lot of security features installed which would make it hard for a tech to troubleshoot (needs passwords etc to be shut down or rebooted) and I store some cryptocurrencies in wallets on my phone.
Is it worth taking it to a tech (I live in Japan, and don't speak much Japanese) or should I be looking at an upgrade? If so, what is the recommended phone from Sony currently? I honestly really like the XZ Premium, so I'm tempted just to buy another one if mine can't be easily fixed.
Thanks!

Bit of an update.
I managed to get my phone to charge using the original Sony USB -> USB-C cable, with an adapter plugged into the thunderbolt port on my laptop. Charging is still incredibly slow though. Also, I noticed when it hit 30% charge, it stopped accepting charge unless the phone is unlocked. If I hit the lock button, the charge light switches off. It switches on again when I unlock it.
*Small edit* It stopped charging again at 31%, despite being unlocked.
Wiggling the cable in the phone socket doesn't seem to effect whether it charges or not, which should rule out the connector in the phone. It has also not registered as a device on my laptop, despite being connected via the USB cable, which would mean it's not specifically a battery issue either, as there's no data connection being made.
So I'm starting to think it's a hardware issue.
I've ordered a new Xperia XZ Premium, because I really do love this phone, and the new XZ2 Premium doesn't seem like much of an upgrade to me apart from the camera, and slightly faster performance. And as much as I'd love to have wireless charging, moving the finger print sensor, and no 3.5mm audio output is a massive dealbreaker for me.

mine died like this, was on charge, started to say charghing/discharghing until he turned off and never came back.. under warranty they changed MoBo/2 stickers/components (??)/ 2 screw and now is back like new

Long term bump.
I bought a new replacement 8142 and have been using that successfully, and I decided to try and fix the charging issues on my old one.
I've just installed a brand new genuine battery, charging port, and power/vol/camera button connections.
The phone booted up fine, but it's STILL not charging at all. Any ideas? Motherboard maybe?

Maybe the flex cable isn't working

have only just started having this issue yesterday, have tried different charger and usbc cable combinations, cant even get my pc to recognise it as a plugged in turned off xzp and it wont turn on only show the battery icon with low level indicator in the red.

I have a similar issue.
When I connect my XZP to the pc using a Rampower cable USB-C to USB (sold as 5Gbps and 5V/3A power, thus an USB3.0 with fast charge of 15W) I suffer of the same issue exposed above: randomly the connection get interrupted.
While, charging the phone, yet with the above-mentioned cable and original Sony charger, I get no problem at all!
NB: I have never tried with the original USB cable...

Common fault with the xzp.
The actual connector from the logic board that the usb c module connects to burns out. Require a new logic board or connector to be replaced/soldered on and new usb c module.

This is good news, because sourcing a mainboard is half the price of the phone, and I've already spent money on a new battery and charging port etc.
My 2nd G8142 phone has just started displaying the same symptoms, and I can't afford a complete replacement.
Can you confirm that this is the part I need? https://www.aliexpress.com/item/4000160901916.html
If so, I'll grab 2, and install into my old phone first to confirm the fix, before then installing one in my newer phone.

Lucky you!
I'm onto my 2nd one, and have had the same charging issues with both.
Both phones have been rooted with a custom ROM, and I use my Dell smart-powerbank to charge them fairly often. So perhaps that is the cause of the early failures on both.

I have unlocked both on day one :laugh:
I have never used a powerbank, could be a factor. Or just bad luck
My first xzp, i cracked the screen trying to replace the screen adhesive, so i bought a rosso red one from ebay.

Unfortunately I can't confirm if that is the exact part you need as I don't do repairs. All I can confirm is that my repairer has stated that he has seen XZP's with the same recurring issue with the connector burning out.
My guess is, that is the part as he had to micro solder a new connector to the logicboard.

That's good enough for me! I'll grab a couple of them and see if it fixed my older phone first (because I've already tried the battery and the USB-C socket etc) Will update once I've done the repair.

Hope you can fix that problem and share some experience on this issue. Mine has a similar problem. The difference is that it can be charged to 100% but very slow and randomly stop.

Yep, that's how my issue started too. It'll progressively get worse.
I've just bought a Google Pixel 3 XL as my 2nd XZP has ceased accepting any charge at all. I'll see if these motherboard sockets fix the issues, then keep one and sell one. Otherwise I'll just sell them both off as parts.

I talked to some tech on Alibaba (A Chinese shopping website) and they said it can be fixed by replacing that socket. But the replacement requires professional welding equipment and skills. Or the motherboard can be damaged. That's why I am looking for other people's experience before I take step myself. If you succeed, please update this thread. I think there are more people like me who is looking for successful experience from others. Thank you for your sharing.:good:
