I have a T-Mo TP2 (currently still on the stock 6.1 ROM). Last week, the USB connection stopped working, out of the blue, and I'm no longer able to sync or even charge via USB PC connection.
Whenever I plug the phone into a PC (any PC, not just the one I use for Outlook syncing), the orange charging light turns on for a sec while the PC indicates it's found new hardware. Then the light turns off as I get an error on the PC (in Win 7, and a similar one in XP):
USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.

This happens regardless of whether I set it to ActiveSync or Disk Drive mode, and under ActiveSync mode, unchecking the "Enable faster data synchronization" box doesn't make any difference.
I'm able to charge by plugging into non-PC USB connections (AC adapter, printer USB port, etc.).
Any ideas? I'm looking to swap out the ROM but figured I should fix this before doing so...
A similar issue happened to me. But mine could charge using the PC. I've heard the low quality cable can be the issue. But wasn't on mine. I had to return mine and the new one is working fine now.
I think mine broke because i've used a 3rd party charger to charge my phone. Did you do the same thing?

This cable was working for four months, but I tried another couple to test in any case- same thing.
I've used the iPhone's USB AC adapter a few times to charge, but that shouldn't make any difference (its output is the same as the HTC adapter- 5V, up to 1A).

Under USB to PC, under ActiveSync, I see a box for "Enable faster data synchronization," which makes no difference. There's no box for advanced networking functionality (this is the stock T-Mobile 6.1 ROM).
I tried yet another cable, which now seems to occasionally work for data syncing, but it doesn't seem to charge from a PC, and every once now gives an error:
Warning
The charging current is not enough for device power consumption. Please shut down unused applications, or switch to AC adapter.

Might be a hardware issue, but apparently there's no warranty at all on these devices unless you buy one separately (which costs about what an iPhone 3GS would, so I figured there's no point), so hopefully not.

i am getting an error message saying "USB device not recognized. One of the USB devices connected to this CPU has malfunctioned and windows cannot recognize it"
when i plug the phone in to the usb plug the charge light comes on for a sec, then i get that message and then the light goes off. I feel as thought i may have damaged the mini usb port (the cable is a snugger fit now) on my phone due to a drop, but it still charges thru the wall and has worked since the drop on the cpu, but now i am getting that message.
Help!
Are you having trouble making phone calls? I had this issue one time in my hermes, and its a brick now!
No, phone functionality seems fine...data and calls.
btw, the light also comes back on after the phone goes to standby.
Change the USB cable and see if it fixes it! If not, it might that the pins are getting a bit worn out in the phone.
don't have another cable to test right now, but the same cable works for another phone. not sure if that proves anything, but it's all i know for now

Have you reboot your phone and your pC?
mine doing the same thing. thats why I looked at the tread hopeing someone would have an answer. I guess not.
MS6 software, windows vista ultimate.

Yes. From past experience with various charging issues with different Hermes before (car chargers not able to charge unless powered off, then rebooting plugged in to keep the charge going), finicky usb cables, etc. ), I know that the hermes can be funny with charging/syncing to begin with. But since i had dropped it and it landed right on the port and bent it a tad, it really feels like something got damaged a bit. Not enough to eliminate the charging from working, but enough to give me problems....like this.
Example, i have never had this problem in the wall before, just mainly in the car, and even then it's usually when the battery is very low: When i plugged the phone into the wall last night, it wouldn't charge right away. once it went to sleep mode it started charging, but i i power it up the charge light goes off.
try
HKCU\ControlPanel\Comm\Cnct = `57600 Default (string)
to
HKCU\ControlPanel\Comm\Cnct = `USB (string)

it work for me
thank you for the tip, but no luck still
in the "USB to PC" under your system settings, the box to "enable advanced network functionality" sould be checked by default, uncheck that box and you should be able to connect and sync through usb with no problem
I've done that...it feels like a hardware problem, but since the port works kind of it's hard to call it a hardware issue. techs i've talked to have said if it works at all then it must be software related
Hi.
i got a unbranded Touch Pro2 in france. the battery stand 2 days before the first recharge. but seems i got a problem of recharging.
i decide to recharge it when the phone is ON, but seems it consumes more than recharge speed. there are less and less electric in the battery, even the screen is Off, and no applications running, and all connections are disabled (WIFI, Bluetooth, Data Connection) except Phone
so i have to take the phone completely OFF, with a cable USB connected to the computer, now it is more than 6 hours, but the recharing light is always "Orange".
this is my 3rd HTC phone, and i never met this problem before. as the first recharge of TP2, is it normal to me?
thanks in advance of your help

Thanks, nearly 6.5 hours with usb cable. the light turns green, so i can start it now.
but i still not understand why it consumes more quickly than recharge. i will see if it happens only in first charge.
I saw somthing somehwhere about turning on quick charge or full charge via activesync usb, dont know what its about but its worth investegating if this is a problem for you.
I have another charging or connection problem, with all my other htc phones (5) i could use any regular usb cabel, with the pro 2 they all seem to have poor connection, have to hold the cabel in a sertan angel for it to work. The supplied cabel and the org cabel for my pro 1 works fine though. Anybody else having this issue?

same here - but applies to all my htc phone. they can not connect stability with the mini-usb of my SLR camera. in fact, there are a little different with HTC ext-usb and mini USB -- the port is a Right-angle trapezoidal, while the standard mini-usb is Symmetric trapezoidal. so that's why we should use the ext-usb cable.
same here with the usb cable ...well is not the usb cables problem but the usb plug in the phone .
concerning charging from a pc laptop.....
if i leave my phone overnight charging from the laptop and the laptop goes into standby ,even if the battery is 100% it gets totally discharged with in hours!!!! this while plugged into the laptop!!!
what a hell is this , i mean, m i charging the laptop from the pda or what!?
this is a serious bug that htc needs addressing.
please note that there is laptops that do not power down usb ports while in standby, i got one that does just that.
now my eee-pc1000h doe power down the usbs ports when going into standby.

Well i know that but that is becous they also have the headset on the same port. As far as i know you should be able to use a normal usb cabel with the device.
USB ports on a computer can only supply 500Mah of current. it seems really odd that the phone would be discharging at such a rate to deplete itself even with that current available. that would seem to indicate the 1500Mah battery in the Tp2 would only last 2, maybe 3 hours before dying if left unplugged.
when connected through a Wall outlet the phone should be being charged at 1000Mah. although the maximum safe charge rate of the battery is 1.5Amps (1500Mah.)

I have noticed that my TP2 can complain with a popup warning that there is insufficient power to charge when connected to my Dell laptop. I think it just stops charging at this point. After that it is downhill all the way!
I agree that there is something strange going on with the TP2 recharging from a USB port. I got my TP2 as a replacement for my HTC Universal. I am using the TP2 on the same port with the same cable. The Universal was very straightforward - plug it in and it charged regardless of whether it or the PC was on or off. The TP2 is very different - leave this connected to a powered off PC overnight and I routinely find that the TP2 has reached critical battery low the next morning. This means that not only does it seem not to have been charging, but it must have been "on" overnight (where the power management settings should have turned it off) in order to deplete the battery to this extent, regardless of whether it was charging or not. The battery charging light (amber to the left of the ear speaker) is on throughout.
The power management information is also odd. This AM it reports last full charge at 23:12 last night and since last full charge a standby time of 6h39m, talk time of 0 and device usage of 2h55m. However, it wasnt used at all after about 20:00 last night and power management should have turned it off after 30 mins.
It charges normally from the USB port when the PC is on.
Any ideas?
This problem happens with standard USB cables and the official HTC cable. You must have an active ActiveSync connection or the phone won't charge.
Last night I plugged my phone in while my computer was still booting. The charging light came on, but this morning I was left with 10% battery.
If you plug it into a computer without ActiveSync installed the phone won't charge.
If you plug it in and the ActiveSync icon turns green the phone is happy and will charge.
If you turn off the phone and plug it in to just about any USB power source, the phone doesen't know better, and it will charge.
I got the power error in my car last weekend. Running with the splitter, with 3.5mm into car sterio and car charger plugged in. Was running slide2play and the pop up showed up. Come to find out, later on the charging light wasnt on the phone anymore. Tried the wifes tilt 2 and it wouldnt charger hers either. The car charger died.
BUT, at the time the error came up, the charging light was up and running.

Problem with TP2 and Mini USB sync/charge cable
I have an unbranded GSM TP2. It charges normally using the HTC wall charger and the HTC supplied ExtUSB cable.
I have read that Mini USB cables should be compatible with the HTC ExtUSB port for normal operations like charge and sync so I bought a generic Mini USB sync/charge cable on e-Bay. The supplier stated it was compatible with TP2, but when I plug it in to USB port, the device charging light comes on for 1 sec then goes off and the PC shows a message saying "a USB device has malfunctioned".
The supplier sent me a replacement cable but it has exactly the same problem so I don't think the cable is faulty. I think maybe the problem is with my device.
Does anyone out there have more detailed knowledge of the compatibility of Mini USB and ExtUSB?

I think the odds are you just got a bum USB cable...the failure rate among the generic ones on e-bay is considerably higher as a rule. Do you or any of your friends have any other mini-USB equipped devices you can test it with?

That was my first thought but I have now tried three different cables, from two different e-bay sources, with the same effect. However, I haven't yet tried any of them with any other device - I'll try that at the weekend and see what happens.
Anyone else having this problem. When I have my TMOUS TP2 hooked up to USB I keep getting told it's not getting enough power to charge.
Interesting. Is the USB plugged into a USB hub or straight into a computer? I can charge mine via USB when its straight into the computer. I'll try with hub a second to see if there is a difference.
Edit-
No, I cant. When plugged into a 4-port USB hub, I also cannot charge. I'm using some generic nonsense hub, dunno if a higher quality one (or one that also plugs into the wall for juice) might make a difference
Yes!
Many laptops are not powerful enough to charge the TP2. Also many hubs will divide the power between the ports.
A standard USB port will give you about 1A and the above mentioned gives you typically less than 1/2A.
Putting TP2 in standby will help if on a weak port, but that makes no sense, cause then you can use the charger.
It's directly in to my PC.. weird.
I got the "not enough power" USB warning when plugged into my laptop...but not right away -- it had been plugged in for 30-60 minutes or so.
I have not received that warning when plugged into the USB port of a full-power-desktop PC, even when plugged in for hours.
I try to remember to bring the ac adapter that came with my TP2 when I'm going to be away from home for a while so I don't have to depend on USB-power from a computer.
I charged off a 0.5A power source (the most you'll get out of a standard USB port), but the device was turned off. Took about 3.5 hours to fully charge it.
Did you have anything like wifi, gps, etc turned on at the time?
how much power is left on the phone? IIRC, if its too low, your phone will not charge through USB & you need the AC adapter.
There are "powered" and "unpowered" USB ports. The "unpowered" ones just basically carry enough current to carry signals, but not actually power a device. The "powered" ones carry enough current to charge a device.
Many laptops are "unpowered" ports, although I think that trend is changing. Most desktops I would assume are "powered".
I personally only power my phone on one of two official chargers I have, although if I'm in the car I'll use a third party adaptor there.
I don't know if the TP2 is any different than the Tilt in regards to charging, but I'd assume very similar.... Perhaps I'll have the TP2 soon, I've finally gotten ATT to let me have an early upgrade but haven't found the actual phone yet.
I have a 5v 1A car charger. When in the car if I am using Pocket Player, and my GPS program at the same time I will get the message that:
"there is not enough current to properly charge the device. Please should shut down unneeded programs." or something like that...
And sure enough, my phone will die if left like this. It won't charge, even though it shows that it is... curious.
Could it be the cable is not allowing enough current? I am using an older cable in the car, as I have my TP2 supplied cable on my computer....I am going to try swapping these 2 cables tomorrow and see what happens.
I've had my Sprint TP2 for 12 days now and experienced this problem once. I was plugged directly to my PC via the USB port. I believe my battery was at about 30% so I disconnected it and used the travel charger for awhile and plugged it back into the PC USB port. So far that's the only time it's happened.
Might be the cable!

Hello,
I had exactly the same problem and found out it WAS the USB cable - the one used couldn't offer more than 300mA to the phone, even if connected to orriginal HTC AC adapter. After changing the cable, the 1A car charger gives the same mA as the AC adapter (checked with nuePower - http://www.nuerom.com/BlogEngine/page/nuePowernueBattery.aspx)

Thanks for the info.. I haven't driven anywhere since I posted that! I will be in the next day or so... glad to know the answer is simple.
I too, just downloaded the NuePower program. Will be installing this as well. Did you by chance have the chainfire 1% battery cab installed? If so, did you unistall it first? Wondering if there will be a conflict between the 2.

Hi,
Yes, I have chainfire's cab, I didn't uninstall it before installing NuePower (btw, I have tried once to uninstall it and after a soft reset, the 1% info was still there). the only bug I saw was when pressing the OK button in NuePower - sometimes phone hungs or runs very very slowly. Best is to use it only to test the cables and uninstall it. and don't press OK button, just minimize it with End Key or do a soft reset if handy.
Mine does the same thing lol
I get the same thing, i think they should make these devices use even more power.
Don't know if will help, but last night I was in my car using Live Search for GPS purposes. The battery was low on the phone, so I plugged it in. The phone told me that the source was not strong enough to charge the phone and to try shutting down some apps. I assumed that it was because the GPS was still active, although I really don't know because I didn't bother testing that theory, as I was just around the corner from my house. (No jokes about using the GPS to get home, please. )
Anyway, when I got home, I plugged into my laptop (which was running on AC power) using the cable that came with my XV6800. Note that the cable is always connected to my laptop via a cheap USB hub. I experienced no problems.
I just bought a ReTrak MicroUSB retractable cable for power and sync. Power works fine, but my pc(s) will not detect it as a device, doesn't even think about it.
Anyone else used it with a Captivate? Their site says it should do sync, but maybe that's not directed directly at the Captivate.
I just heard back from ReTrak Support, according to them they had a bad batch get shipped that will charge but not sync. They are sending out a replacement for me today.
Just incase people are actually reading this. So I received the new cable from ReTrak, and, well, the same thing. Charge but no data. I informed my contact that maybe they don't work with the Rogers variant of the Captivate. Now they are over nighting me a new cable, different model to try/test. I was ready to let it go and just live with carrying an extra data cable (I really like the "retrak" feature of their cables), but will try this new model and see what happens.
Interestingly enough, I had this same problem, but not with ReTrak. It was one of the crappy retractable units, though. I noticed I actually had power problems with it too. When the phone said it was charged to 100%, and I unplugged the cable, it would drop 10-20% on the battery indicator immediatly. Thought I had all sorts of rom problems, did tons of time reflashing ....
... and then I replaced the cable. Everything worked peachy after that. If you're having charging problems, this is likely the culprit as well.
No charging problems for me, just no data.
Sent from my SAMSUNG-SGH-I896 using XDA App
So I received the ETCABLEMICRO5 and it works just fine with my Captivate. It is a different cable then what is in the ETCHG41MO2 4-in-1 package (12VDC/120VAC dual USB outlet with retrak cable). So, until/if they change packaging, buyer beware. The ETCHG41MO2 will not do data sync with the Captivate, it needs to be a ETCABLEMICRO5.
Does the ETCABLEMICRO5 charge in high-speed mode, or just at the standard 500mA USB rate?
Settings -> About Phone -> Status -> Battery Status will tell you if the phone thinks it's connected to a charger or a standard USB port.

This is not a problem with the Captivate, but a problem with the cable. I bought a ReTrak car charging unit for my HTC Droid Incredible, and initially, the data Xfer worked fine, but now it does not. My cable at home works without a hitch. Looks like this is just shoddy craftsmanship by the company.
Note: Charging feature works fine, which is why I purchased it in the first place.

Send in a ticket to their support, they are prompt and very nice. I'm sure they'll replace it for you (and let you keep the old one).
I seem to have an issue that my phone never charges whilst connected via USB to my Macbook Pro. I have also tested on a Windows machine and have the same issue.
I was able to charge my Sensation over USB and I know that one of the ports on the Macbook has a higher output for charging but it makes no difference.
The phone states that it is charging but the percentage charge continues to drop. If I switch the power off it will charge. There doesn't appear to be any big battery drains though. I ran for a day and twelve hours over the weekend and charged at 40 percent.
Has anyone else the same issue?
Btw, I am on stock 4.0.2, rooted but not running anything else that should have any affect

How old is your macbook pro? Or more to the point, do you know if it has USB 3.0 ports? If your higher output ports are just 2.0 (and your computer is describing them as such compared to the older 1.0 spec) then you are stuck at 0.5A (half of wall charger output). USB 3.0 goes up to 0.9A, but I don't know if there are any catches in terms of devices needing to request the bump.
When you say that it charges if you switch the power off, do you mean it only works if you actually power down the phone? As in, leaving it sleeping plugged in, it still won't charge? Keep in mind that actively using the phone with the brightness turned up high could result in overpowering the .5A current in.
Unless you know someone else with a GN you can test you might just want to take it into the store and have them try it there/consider a replacement if it's defective. Also worth exploring if it's just the battery is defunct, if you have access to another one.

Really? Source?
Doing a tad of research it seems some models front (closer to the front) USB port has slightly higher output than the back (closer to the screen) USB port because the back one shares a USB controller with internal components.
It couldn't be noticeable though, they're both simply rated at .5A .

MacBooks don't have USB 3.0. Its always been standard USB 2.0 afaik.
I'd also recommend that OP check different cables and computers, or different batteries if possible.
I have the exact issue. If I charge via USB on ANY laptop/computer it takes forever and if I'm using the phone as it's charging it uses more power than being supplied so it loses battery life even though it's plugged in.
I had this problem on my iPad too. It seems they need more power to charge but can still "trickle" charge off of a standard USB port.
My batter was at 10% last night, plugged it in to my laptop and sent some texts and left the display on (dev settings), about 10 min. latter it was at 4%.
I mean to post this last week!
See the screenshot....Status 'Charging' however as you see from the lower part of the screen, it has clearly stopped charging some time ago (about 3 hours earlier!)
It turns out that the CABLE was the issue....I thought all Micro USB cables were created equal, evidently not
Any ideas what the differences are in micro USB cables and how to identify which ones 'work' and which don't? I bought 10 from ebay which all seem not to charge from USB
I've had no problems charging via my pc using Samsung or Motorola cables. It charges slower but it still works.
