(Yes I mention android development but this is regarding a 'general' topic)
As an android app developer, it's pretty much mandatory that I have my devices plugged into the computer for ADB. However, with wifi / bluetooth / GPS / screen brightness turned on or cranked up, I also need to have the device plugged into something that provides more than the measly 500mA that the computer's USB port can provide. From what I've been able to gather, the USB standard requires that USB hubs and ports cannot supply more than 500mA to a connected device. However, I suspect that there are manufacturers out there that are aware of the need for simultaneous charging + connectivity and have made special cables specifically for this (What I'm thinking of is a Y usb cable where one end plugs into the device, one plugs into the computer and only uses the data wires, and the other plugs into the charger which feeds and charges the device.) Do any of you know if something like this exists and where I can find one? I've definitely tried to Google for it but the phrases I'm using are long and not producing the right results. I obviously don't know the correct term(s) to search for.
If I knew a bit more about circuitry in general and the USB standard specifically, I could probably solder together a cable like this with a couple diodes to prevent the charger from zapping the motherboard's USB, or perhaps, as mentioned, not connect the power wires at all. I do have 6-8 spare cables laying around but I'd rather not start chopping and black-taping unless I get some confirmation Plus I only have one female end to mangle, so... yeah ;p
My idea for the splice & solder (in case no commercially available alternative exists):
Code:
computer - 2 data -----\
|----------------- device
charger - 2 power -----/
Most chargers and phones have some kind of regulator circuit built-in anyway, at least that's the impression I'm under. Generally if you crack open a charger there are only two cables black and red (+/-) which makes things considerably easier but that's assuming you have a charger that's just for charging and not one that requires you already have a usb cable to plug into it (like some that come with phones now). Standard wiring color schemes applied to all the cables I've cut open and spliced so as long as you go black/black red/red from the charger and leave the other wires untouched you should be ok. You'll know if something's wrong quickly because your phone will get quite a bit hotter than normal and do so faster, and you shouldn't need to add any components as they're already in the charger circuit (diodes to prevent current flow-back, resistors and the transformer to convert to dc, capacitors to smooth the current, etc). Just use common sense when working with this, don't solder until you test, don't splice wires together that don't seem right, use a multimeter to make sure you're getting the proper wires, don't work on anything while it's live unless you're properly insulated and even then not if you can help it, all that jazz.
Yeah, my biggest concern would be that I was told that some USB devices negotiate current requirements with the motherboard, which I'd assume goes over the two data wires, but I remember landline phones have 2 wires but both power and data flow over it, so I wasn't completely confident that the two power wires weren't passing data as well. If I run the 2 data to the computer and the 2 power to the charger, and it turns out that the negotiation requires all 4 wires be connected from the device to the computer, then I've just ruined two good cables.
I just am not so super confident in my logic and theorizing that I'd want to risk frying circuitry If I can nab a commercially available accessory that does this for $30 it's a lot less than having to buy another $700 device and a new $200 motherboard (at the least)
I don't think you really have to worry, but I wouldn't replace the charger wires, I'd connect the wires from the charger to the power lines inside the usb cable that way even when the charger isn't plugged in the phone is still getting some power and it'd basically be hooking them up in parallel when the usb and charger are plugged in. You could always go buy a $20/$30 cheapo phone that connects through microusb-to-usb and test the cable on that through a USB hub. that way if something goes wrong you're only losing a cheapo phone and a usb hub, but honestly things shouldn't fry as long as you get the wiring right and don't try to do something like black to red because then you're feeding power from the charger back into the usb socket which is where things get ugly.
I think i've found something on the interwebs, that will actually save you the wire-splicing and soldering
It is actually just what you described, it uses 2 USB ports in order to provide 1000mA to a device.

I know that some of the smaller usb external drives have a cable that has 2 "type-a" connectorsto allow data connection/enough power for the drive. I have not seen these in micro-usb form, only mini-usb. SO, I do not see why it would not work.

Agreed, USB offers about 2.5v of charge aswell as data connectivity of course, I don't understand why it wouldn't work... I can tell you from experence through that it does take about 40% longer, and will suck the life out of a laptop if you are using it on battery mode.
The reason I was thinking about cutting the power wires from the computer entirely is I don't know what dumping 1-2 amps into the computer's USB port is going to do ;p
Edit: Looks like newegg.com/Product/Product.aspx?Item=N82E16817707145&cm_re=2a_output_usb-_-17-707-145-_-Product should do what I'm interested in, if the details are legitimate. Who knew finding a hub with full details would be so hard? ><

just as papabear already said, there are also external hdd, that use this kind of wire.. so it should be no problem. If the ports arent't capable of delivering that power (but as far as i know they are designed for 500mA each), simply you will not get the the full 1 A.
And i must agree, hardware vendors rarely add detailed power info -.-
Okay so my usb port has been a bit annoying the past week - where i had to vigorously wiggle the cable to get it to charge or to sync (and even when it did decide to connect to the computer, it would chop out eventually)
But now it's no longer charging or being recognized by my comp
It's strange because the headphone adapter was working fine, and so was the usb host, but it just wont charge anymore - I effectively now have a dead TG01
Currently, i'll get the orange light, telling me it's charging, but when i try to power on, nothing happens...
So i'm thinking a new USB port which is where I need some help: I'm not sure on what part to get
But maybe This is the one? Comparing the images with the ones found on the net of the TG01 (Yep - I still haven't got mine open yet)
But yeah, just a heads up on whether you think it would work would be epic, or whether you think i should just try a different battery/charger/throw it away (Although i'm almost certain it's the port, as it was working intermitently before - it's now gone altogether)
are u using only usb to charging or an wall charger?

Wall charger, but i tried USB, and still no luck
It just wont charge at all, regardless of the orange light when plugged in now that it's off (though i wouldn't get it when the phone did still have charge left and was therefore still switched on...)
BUMP: Any ideas you clever people? Just some guidance would be nice...
I'm still without my beloved TG01, I'm having to use a **** old Samsung G600
I do have some problems of my own with my USB cable. I believe the problems are due to the cable, though. The wall charger works fine. The USB cable that I use, has to stay somehow "forced"... imagine having the cell laying face up on a desk. The USB cable gets out and is forced by a small pen that stays right near the cellphone, to have a 30% slope upwards, so pushing a bit the cable onto the upper part of the USB port. I do know that you are telling us a different issue, however, maybe this way you could check whether it's just a broken connection and not a completely dead port.
No, this sounds like the exact issue i had...
It was like this with the Charger and USB - where i had to force it to be recognised or charged, and it would still cut out after a while - and wiggling it or knocking it wouldn't actually affect it, it would be of it's own accordance...
But it was strange because the headphone adapter worked fine...
Nothing happens at all now though
Are you try: Settings- Connections- USB to PC- unmark Enable advanced network functionality
I can't turn the phone on because it wont charge, so it's not that
Battery may be defective. Try with any 5V charger, connect directly to battery pin in 10 min
Hi
It vaguely remembers me of something I read on the forum about different micro usb (explaining my different cables do not connect just the same, some easy, some bit forced); I think there also was a drawing. (but I don't have time to search for the exact thread; it was not the "solving usb port mistery one))
Maybe your earphone adaptator don't have exactly the same as your charger? And if it is not battery trouble, find a charger with the "very right" micro usb plug?
Thank you both so much for your response:
I understand why you say it could be the battery problem with the charger - but it doesn't explain the intermittent connection with my computer when using the USB cable. Which is convincing myslef more and more that it's a port problem
One solution for now would be to buy one of these cheap external battery chargers from eBay, but it would mean i still wouldn't be able to use sync using the USB cable and i'm a bit conscious on whether the charger is safe and wont fry my battery
Which is why i'm leaning towards having a stab at reparing it myself
It'd solve the issue directly and it'd be a safer and more secure solution too... (the external charger would have to be ordered in from Hong Kong eBay)
I'm having what seem to be exactly the same problems. I have used 2 x usb based chargers on it - and neither work (whereas they had been working for the past 6 months). Got a mains charger last week - was working for a while - but as of right now, no longer works.
I'm not sure what else to do. I will try later to use the other adapter I have for connection to usb keyboard. The strange thing is - this will probably work but charging won't!
So....is it the micro usb port that's broken? (strange if it is but still works for data)
OR
could it be the battery?
I got my Triumph and it will not charge no matter where I have plugged it in or fiddled with the charger. It does not matter whether it is on or off. I have been using the wall charger that's included and I have tried USB through my computer. Before I go to the hassle of sending my triumph back I wanted to see if there is a solution. Thanks in advance.
The first one I got did this sometimes as well. I took it back and swapped it.
Jumpstart
My triumph would not even turn on strait out of the box. I had to "Jumpstart" the battery, here is a link on how to do it. thejosea.com/2011/02/jump-start-your-droid-when-no-wall.html (Sorry i cant post links yet, gonna have to copy paste)
You pretty much have to charge the battery by its self outside of the phone. Once you do this let it sit charging for about 20 minutes then try to charge it through the phone.
You should only have to do this once.
It seems like the batteries are not being shipped charged and they run "Dry".
You MIGHT want to try a different USB cable.
I'm using my Nook Color adapter(1A) and a generic USB cord which works fine, however one time I accidentally used my Optimus V cable and it would NOT charge while the MT was up and running, however it WOULD charge IF I powered down the MT...
I haven't even tried the cable that came with MT yet... nor have I tried charging via a USB port on my nb, but I imagine that would be REALLY sssslllloooowwwww....
I exchanged my device for a new one, and with my new phone, when plugged in, the lock screen no longer shows "Chargin" with the %. Any ideas how to bring it back?
It only shows that if you're on an AC charge. If you're on USB it won't.
I've tried on 2 different AC chargers and it still doesn't display
Same cord? The AC pins have to be shorted or it won't go into AC charge mode. I have a couple of USB cords that work fine for connections to the computer but will not go into AC mode (the USB cords that come with the Optimus are known for doing this on other phones, incidentally....)
It'll charge without AC mode being "engaged" but at the 500ma rate instead of the 1A rate, so it will take a lot longer.
the answer is simple.....due to crappy crappy design of micro usb the charge port actually comes un-soldered from the board and obviously it no longer will charge nor will usb work!!! now before you ramble on with how do i know i wondered why mine wouldn't worked i opened the phone and notice the micro usb pins were not attached anymore....i have sent this in to Motorola which gives you a 2 year warranty instead of virgin mobiles crap $5 a month insurence then you still have to pay like $100 to get a new phone!!! so i will post how everything goes so far i know the repair center is in McAllen TX and they give you a free 2day shipping label valued at $100 to send in the phone!
You might want to try plugging it into a wall (not pc) and leave it for 20 minutes. Mine ran completely dry one time and it wouldn't display nothing until it charged for a while. If you've already tried this then definitely take it back.

*update* They are fixing my phone now and i should get it in 5-7 business days no problems they received the phone and started the repair
I had the same problem but different solution.
I too let my phone completely discharge to find that it would not indicate that it was charging or even power on with or without the battery being present, but I "jumped started" my phone. This is a weird technical solution that went as followed in its entirety, meaning, some of these steps might be pointless or useless but I did them and I now have a working resurrected MT in my hands that is charging. This solution is assuming that there is no problem with the micro USB soldering on the main board.
"Jump Starting"
1) Remove the back casing and your MT battery and place both to the side, but keep the battery close by for polarity reference.
2) Have another battery of the same 3.7v that is charged (disregarding mAh).
3) Now here is the fun part and pay CLOSE ATTENTION to POLARITY!!!
-Get two spare wires, preferably of different colors so you can tell the [+] from the [-].
-With the spare 3.7v battery you have, in what ever way you can, connect your spare wires to it, paying close attention to polarity.
-Now that you have your spare battery wired, CORRECTLY connect the wires to the inside connectors of your MT what ever way you can, paying close attention to polarity.
Being [+] connected to [+] and [-] connected to[-]
4) Boot your phone until you know you are at the home/lock screen. Then remove the wires from the MT battery connectors.
5) Use this same battery and connect it to your battery for about 30-60 seconds, paying close attention to polarity. This will give the battery some juice for the system to recognize.
6) Place the battery back in the phone without attempting to turn it on and return the back case to the closed position.
7) Now connect your MT to a powered micro USB cable and see if the red indicator charging light turns on.
-If so then great!
-If not then you may have some other problems
-If yes and no, as in the cable has to set a certain way for it to charge then just keep on reading for that fix as well.
"Loose Connection Fix"
This is how I fixed my loose micro USB cable and it worked for me, but I do not have soldering problems on my main board of my MT so proceed if you think this will help.
1) Your micro USB male side of the cable that plugs into your MT should look something like this (excuse the crude drawing of letters)
{the dots are empty space}
____________
\................... /
\UUUUUU/
2) Get a pair of needle nose pliers and SLIGHTLY pinch/squeeze the center of the male port closed so it looks like this
____...... ____
\.... \...... /.... /
\UUUUUU/
Except not that extremely bent inward, but you get the idea.
This will force the male tongue in the MT charging port to be forced onto the pins inside the micro USB cable for a better connection and thus fixing the loose connection problem
I hope this helps someone, it helped me save my $300 paper weight from actually being a paper weight.

I let my battery die down and also did a battery memory reset, then the phone acted bricked.
Then I tried this to revive and it worked!
Thanks for the help here I did this but when I connected the batter to the phone nothing happened. I connected battery to battery let sit for about 90 sec put it in phone and plugged in and the red light is now on!
Thanks!
Well,
add my phone to the list. It started about 2 weeks ago when after completing charge, instead of maintaining trickle charge it just let battery drain. I woke up couple of times in the morning finding the phone's battery on it's last legs. Now it simply refuses to charge by anything but my car charger. Lucky for me (and I thought I would never say it in my life) I have a long commute to work and it allows me to recharge the phone while I enjoy typical traffic delights.
I am going to call Motorola and discuss my options with them. I hate doing this as my phone is long since rooted and running CM7, so I will probably have to revert to factory settings before sending it off and if they decide to exchange I would be running a chance of receiving one with bad GPS.
yes i've had this problem to i have to charge my phone on a Samsung charger no motorola charger will work on my phone.
Sorry, I'm somewhat new here.
I have a Motorola Triumph and it just stopped working. The general idea is that the Micro-USB port was shoved up into the device?
How do you go about contacting Motorola about sending it back to be repaired?
I have delt with this problem SO MUCH, have you tried my battery charging fix yet ? I have the link posted in this section called battery charging fix, Hope this helps you it sucks when your phone won't charge.
Well the problem is that it won't even turn on. I think the battery has some kind of charge but when I hit the power button, it vibrates like it's booting up then stays off.
I don't know that much about phones, but from what I can gather off Google and the various threads on XDA (Great site, by the way!) the general consensus is that it's the micro-usb port.
Granted, I may be wrong, which is a very real possibility. Heh.
Well 2 things, have you replaced your recovery with the clockwork recovery image ? If so try any means nessary to get into recovery, My old Triumph would NOT charge with any motorola charger, I belive this is a defect with the triumph. You might try a powermat of some kind to get enough power to get to recovery & do what my guide says to fix this most pain in the ass problem, Or get another battery & follow the guide. It's worth a shot anyway. otherwise you've got two options replace it or open it up, if you're gonna open it up then get a super fine sautering tip or file one down to needle size, this is how I do precision sautering on circut boards.
No, I had downloaded Clockwork with the intention of installing a 2.3 rom on it, but never got around to it. As for the charger, my Triumph charges with any micro-USB, from my old LG and Samsung chargers to the Motorola charger that came with it. It acts weird though when I plug it into a computer, saying it is connected to a computer, then that it's not, then that it is, then that it's not, repeatedly. I usually just end up turning it off so it won't do that.
I find it weird, though, that now when I try to charge it, the charging light up where the speaker is will not come on, as if it isn't charging. (And I don't think it is charging.)
I've also tried putting it into the "recovery mode". (Like I say, not too knowledgeable about phones yet. Learning experience. ) When I boot it up (into "recovery mode" or "regular" (?) mode) it just vibrates like it should then does nothing.
Edit: It finally did boot into the "recovery mode", but the touch button things at the bottom (menu, home, back, and search) don't do anything, and I cannot get into the menu to do a factory reset.
I don't think it's the battery now? I am more confused then I was when I started, and appreciate any and all help!
So, I'm traveling (for a long period of time) with my TF. One day, it stopped charging.
I took apart the power brick and put it back together, I even tried to freeze it (on advice from some older "not charging" threads), nothing helps.
When I connect the TF to my laptop via USB - it recognizes the TF. When I connect my iPod to the power brick (with its own cable obviously) - it charges just fine. So what broke?!
I hate this, the local stores here don't sell the power brick separately and I don't even know if that's the source of the problem.
This sucks
Sounds like the power pin in the TF port has bent/broken or just has some detritus/dirt/foreign matter in it and is stopping it from charging properly. Have a look, but you might need to check the port with lots of light and a magnifying glass, so not easy while you're on the move.
If you are in the US Office Depot sells the charger and USB cable for $30.
strange thing is that sometime my transformer doesn't charge.
i have to reboot and it start to charge again.
Same happened here. Asus tech wanted me to wipe the device. After trying other options to get it to charge, I did but it didn't wipe... Go figure... But it booted up normally and now it has been charging.
Sent from my HTC Sensation 4G using XDA App
Apparently charging has some history of issues on the TF101.
I just had mine act up on me, went around the house trying different wall sockets and checked that it worked fine via USB to PC. Ended up taking a can of dust-off to all the pins, then shoving the plug hard into the TF101 socket. Now it works.
Should have mentioned I have a dock as well, which doesn't charge either (so problem is probably with cable/brick)
I'm trying to get new ones (nowhere to be found here, but I'm trying to get one sent to me). I tried looking for dust/dirt and different wall sockets, no luck.
Weird thing - I left it plugged in to the wall overnight and it grew from 5% to 15%, so looks like some electricity is trickling.
I had the same problem with mine after I had it for 5 weeks, I just RMA'd it and everything is fine.
Im having the same exact problem. I left it charging over night by mistake the night before yesterday. I only let it charge 3 hours the most because I know the Transformers have known issues.
I tried to charge it this morning and nothing. I plug it into my PC. The PC recognized the Transformer but no charging. Turned it on and off, nothing.
Just put the power brick in the freezer, waiting to dry up to see if it works .
Although the tf charger and cable has a usb connector it is not usb compliant. the charger brick looks for a gnd signal on pin 7 of the usb connector ( normally a usb 3.0 data line) to determine it should supply 15V to the positive charge pin vs standard 5V. The slow charge you are seeing is from the 5V supply . check to see if pin7 is seeing the gnd signal. Are you using a usb 2.0 extension cable as it doesn't have have pin 7 conductor. be careful connecting your ipod as it could accidentaly see 15V vs the 5V it is designed for.
I touched on this in the EOS thread, but I've discovered it's probably not the ROM's fault and some other problem. I was staying in a very old hotel, which I assume had very poor electricity (not sure if relevant, but wife's iphone was charging slowly too, so maybe it could be part of the problem - way too low voltage or something). Plugged the (TF101) in and it charged barely, if at all. If I recall, the wall adapter got hot on the first try (didn't really take much notice as this has happened semi-frequently since I got it - might describe it more as "warm" in the past, where in this case I'd call it "hot") and from then on probably charged to about a max of 25% in 24 hours. So assuming the problem was the hotel, I tried it again at home, where I knew it always worked, and it still doesn't charge. so...
TL : DR - charger isn't charging - thought it was the electrical supply but it's not (though it could have started the downward spiral of breakage)
I tried freezing the adapter, bending pins, hard reset/cold boot, etc as per different threads on the subject. Didn't help.
Tried plugging the USB cord into a PC and it shows up as a connected device - doesn't show charging on the Transformer, but I don't think it's supposed to - so I think that means the cord is okay.
I plugged a Blackberry with its USB cord into the wall charger and it shows "charging" so it would seem that part is okay - but not necessarily definitive proof as it's a completely different device, just my only other USB device I could test.
This all happened right after flashing the newest EOS Jellybean ROM (from #70 to #72 - no full wipe - cache & dalvik wipe only), but I've switched back to Megatron, which worked perfectly in the past, and nothing changed with the charging. So unless it's possible for parts of the EOS ROM to remain (after a full wipe this time), it would seem the problem is with the charging circuit or the battery itself, right? Not sure what steps to take to test that.
I think I will probably try a new charger anyway, as that seems the cheapest of the $$$ options to try first, but are there any tests I can do in the meantime without spending money on replacement parts? At the moment I have it plugged in with the power off to see if that does anything - will update with any positive results
(Sorry for long-winded question, I wanted to get as much relevant info in there as possible. Hopefully I got it all)
Start by buying a new usb cable, that fixed my issue. Wall socket and usb port only trickle charged my tf101 (about 48 hours for full charge) tried all the freezing, bending pins but nothing worked. I then brought a new usb cable as a last resort (Wall warts are quite expensive so i was apprehensive of buying a new one) and it started charging straight away. seemed strange because the charging issue was just out of the blue (No damaged to the cable)
doubt this needs an update, but my new charger and (longer!) cord came today and it's charging my tablet perfectly. thanks for the info
now to catch up on 2 weeks worth of ROM updates
Dunno if its the right thread but I was also wondering:
My TF101 charges perfektly with the Wallcharger (TF to USB Cable + Adapter). But as soon, as I put
an USB-to-USB-Cable between Adapter and TF-USB-Cable to enlarge the range ... it wont charge anymore.
But: if I connect the same config it to my PC... I'm fully able to Up/Download/ ADB etc... so it can't be the connection
at all.
What's the trick? What am I missing?
