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.

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
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...

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.

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?
I noticed today that my charging port seems to be loose. I've never dropped the phone or had any other issues with it. But I noticed that my phone was on the charger and not charging. I then moved the connection slightly and it started charging again. If it gets moved at all it doesn't charge. So two questions:
1. Does anyone know if AT&T warranty will cover something like this? I called and got a really generic answer so I might just have to go into the store... blah
2. If it isn't covered in the warranty, does anyone have any idea where to buy a new port and/or how to fix it??

That sounds like user damage/wear and tear which is not covered AFAIK, unless you got the add-on insurance.
I've only had the phone for about 20.days and I'm always really careful with my phones. I'm going.to take it in the store to see if I can get a warranty replacement... I'm probably not even going to unroot or anything lol. wish me luck.
Have you tried a different cable....the ports can get damaged, but it's typically the cable end that wears and it seems like its the port

I can confirm this...just happened to me , new cable did it...
I tried another cable almost immediately and it was still not working. But I found an old kindle usb chord and tried it... the connection is nice and tight. I had to modify the case I put on my phone so the kindle chord would fit but now it works great and the chord is almost twice as long as the original HTC chord!
worked a treat

Has anyone had this happen? My D2G has destroyed at least 5 USB cables. The transformers that I plug the cables into still work fine, I use them with other cables successfully, its the cables themselves getting borked.
I have opened one of the cheaper cables (with release tabs on the micro end), and the solder points are intact, leading me to believe somehow that the D2G is causing frays in the cord somewhere in the middle.
To confirm,these cables that stop working on the D2G stop working with all devices. Moreover, my Galqxy S hasn't had these problems, with cables lasting forever and a day with it, so it's not a user handling error.
Any way to fix this problem? I may have to give the droid to my wife who lost her phone, but don't want her to nag about problems charging the phone.

Do the cables still work with other phones? Or do they only not work with the D2G?
They stop working on all phones. Seems like the phone is burning out the cords. Not sure though.

Hi all,
For some time now I've noticed that my usb cable do not connect reliably with my s7... initially it seems fine but if i try to use it whilst charging tje slightest movement and charging will stop due to the cable being dislodged, if not disconnected... even if i connect it and carefully lie it down to keep it charging i have to keep checking as i might well come back to find the cable moved ever so slightly but enough to interrupt charging...
I've obviously tried different cables, including new brand-name cables, not cheap rubbish, and the problem continues....
Basically, I'm 99% sure its to do with wearing down of the usb port on the phone itself, although i fomd this quite unbelievable considering the supposedly premium quality of the phone... it is 2 years old now but I've had several android phones and have never seen this problem before...
Anyone else have similar experience? Any suggestions as to whether or not this can be fixed ?
Thank you in advance for any opinions/feedback...

Bump... anyone?
I had a problem with my s8 is port. Took the phone to a Samsung repair shop and they fixed it the same day. You may have to pay for your s7, assuming it's not under warranty (2yrs, I believe).

Hi there, I've had a similar issue which I couldn't understand for a while, as when I tried to duplicate the issue it didn't occur.
Finally realised that my case was the problem - I de-case the phone while charging now and the issue is gone.
It's a long shot, but you could try for nothing before spending repair money
Hope it helps...
