So, I just got a HTC HD2 and am trying to connect it to the PC. By the way, did the TMOUSA HD2 ever come with a cd?
I have a vista and tried to download the Activesync 4.5 but it won't allow as I am suppose to download Windows Mobile Device Center. So, I download WMDC and installed it. I plug in the phone and all I get is "USB Device Not Recognized" . PC doesn't detect it.
I have searched everywhere and tried everything but can't seem to get it going. I haven't anything solid to get it to work.
I tried:
-reinstalling the WMDC
-check and uncheck "Enable faster data sync"
Anybody have any idea? TIA
Is the phone charging LED lighting up when connected?
Have you tried another USB cable and/or another computer?
Then you could boot the phone up in Bootloader Mode. It will say 'serial' at the bottom of the screen. Then plug in the USB cable. The 'serial' should change to 'USB'. Then this might indicate that your computer is viewing the device as a unknown device. This device can be removed and your phone, in normal mode, replugged in.
This may not help, but it's worth a try. Vista has a known issue where it just stops recognising USB devices, even basic ones. Plug your phone in via USB and then restart the computer. When it comes back on it may recognise the phone. If this works then it will be okay for a while at least, but you may have to do this again every now and then.
Vista's basically a bug-ridden bag of gash. If you can, upgrade to Windows 7.
Hope this helps mate.

I tried with a laptop with vista (WMDC) and a laptop with xp (activesync 4.5). The led charging light is on, so it is charging but for some reason device not recognized.
I tried the bootloader (not sure what that does) and it says serial and then I plugged in the usb and it still says serial.
Still not working

I think I tried that already but I'll give it a shot again. At this point, I'll do anything lol. I was so stoked in putting android in this too
does any one think a hard reset might help?
It sounds as though the USB controller in the phone is damaged. I had this problem with my HTC Diamond, and searched for ages trying to find a solution. I manged to flash it with a couple of times with different ROMs (from the internal memory via WiFi) - this did not solve the problem.
I am sure that a power surge from a car charger was the cause of the fault.

it couldn't hurt. i would - see what happens.
try checking cabling first or change the cable
Same problem
I am having the exact same problem. My phone can charge on the computer but I cant sync of even access it via the "Disk Drive" setting. I have tried both AcrtiveSync and the Disk Drive option, unchecking fast data synchronization, reseting the phone, and reinstalling WMDC. I have Windows 7 with the latest updates. I have also tried connecting it to two other Win7 machine with identical "device not recognized" results. The phone and cable and practically brand new. Any help would be greatly appreciated. I'm at my wits end with this phone and it has been beyond frustrating.

I am having same problems have tried on a vista pc, my mac and mac running parallels, nothing works. Reckon it is as fred_up says, damaged usb controller which means no NAND Android for me.
Been having similar problems, but seems to have been less likely to occur if I click "Safely remove hardware" in Vista or W7, and remove the device - yes even Activesync (doesn't seem to be available in XP)
Mark
did anybody find a soulution?
hi
did anybody get solution for this? i m having the same problem.
phone doesnt sync with wmdc, nor connect as disk, only charges itself.
message appears "usb device not recognised"
i have done everything, changed cables, pcs, re installed wmdc, even flashed new roms using micro sd....nothing happened.
is this a hardware issue? why can it be charged but not synchronised?
pls help anybody.
Try another Cable. In my case, changing the cable works. Now i m using my HD mini cable with HD2 and it is working well.

thanks,
but i have already tried all that.
today i called a phone repair shop and they told me that
this could be due to two reasons.
1. usb port problem.-in which case it is replaceable for about 15 usd.
2. problem with an IC (?) of the circuit (guess the motherboard) - in which case
it is either not repairable or very expensive.
i ll keep posting as i go and visit the shop.
if there's another solution pls share here.
Some possible solutions to non-USB
Having come here via a search, I'll resurrect the thread with a brief comment. I'm having the same problem, haven't tried them yet but found several promising suggestions:

HTH
solution...
oops...had forgotten all about this thread, until today till i received the notice about new reply.
thanks for resurrecting the thread.
actually i went to that phone repair shop i mentioned earlier and they fixed it by replacing the usb port. still it didnt work with win 7 laptops. but was fine with xp laptops. dont know why...anyway i have said good bye to my hd2 long ago & using android now
guess lots of people are.
good luck to you all.
Ok.
So at some point I soft bricked my phone and I got the Phone -- ! -- Computer screen.
Managed to get it back into download mode, and then unbricked it by getting it flashed to EB01 as instructed in this thread
http://forum.xda-developers.com/showthread.php?t=1026746
So now I have EB01, which is working, however there is a new problem.
When I try to plug the phone into a computer, it is not recognized (Says the device has malfunctioned).
I have tried 3 different computers. I made sure I used the cable that came with the phone.
I brought it into the Verizon store, and they were unable to get any of their computers to recognize the phone either (we tried a few other cables there as well)
This is both in download mode and within the OS itself.
They told me to try downloading Vcast however that didn't work either.
So now I'm wondering if there is something I can do to get it to recognize it properly again.
Has anyone run into this situation before and managed to fix it?
I did twice have the phone plugged in via usb to my car, and walked out the car (was talking on the phone), and the USB yanked out, so that could have potentially damaged it (though it still charges, so I don't know)
Yanking it out could have very well done it. Only thing I would suggest is reformatting the drivers and attempting again this time leaving it plugged in and rebooting the computer. If that doesn't work, replacement time.
Do you have "usb debugging" turned on?
Did you activate the connection from the phone after connecting to computer? (mine shows a green screen with a button to activate the connection for mass storage)
beyond that... idk.
redownload the samsung drivers
based on the fact that so many PC's have been unable to connect and the info on yanking the USB charger in the car (I think we have all likely done that - though for me it has happened at work with the laptop<->network cable...) you may have damaged the plug/receptor (not sure what would be proper...).
I would do a visual inspection for kicks, though I am sure there could be damage you cannot see.
I believe that these USB connections are a minimum of 4 conductors (some devices are more proprietary and use more pins to ensure you are using an official cable so they can get you to buy more of their stuff - though some of those pins are not actually wired through the cable, but rather short to each other...). If you damaged only one, that could likely be the reason that you can get a charge but no data comm - and since it seems likely that one of the two data pins would be tx and the other rx, then I could see why teh PC would report the device had malfunctioned...
I am guessing here - logic, please don't fail me...
Hi.
I have an Xperia X10 that I gave to my husband. He's good with computers etc.. and he went ahead and unlocked and rooted this phone. It's working awesome - EXCEPT - when you plug it into the computer via USB the computer will NOT recognize it. It says exactly, " "USB Device Not Recognized
One of the USB devices attached to this computer has malfunctions, and Windows does not recognize it. For assistance in solving this problem, click this message"".
Here is a bit of background info:
Before my husband rooted the phone etc. the micro usb port on the phone wasn't working properly - it was loose and you would have to really wiggle it, bend it etc.. to make the debug engage. He did get it to flash/root/unlock/install custom rom successfully ( he installed doomkernel 2.6.29-modFXP-DooMKernel-v06) all while the phones usb wasn't working ideally. At this point he was trying out some settings and branded it as a X10i Generic. (This phone WAS a Rogers phone and we are in Canada). He then wanted to change the branding since x10i wasn't working too great. At this point the USB port on the phone wouldn't engage into debug or charge anymore so we took it to a repair place and they soldered the usb port back - they told us this was common (them coming loose). After they soldered it they said it wouldn't go into debug and that it was because (probably) of the firmware my husband put on but didn't really know.
From that day on this phone has never connected to the computer successfully - the computer won't even recognize it as a memory card - as soon as you plug it in it tries to install drivers and then the computer says exactly this::
"USB Device Not Recognized
One of the USB devices attached to this computer has malfunctions, and Windows does not recognize it. For assistance in solving this problem, click this message"
Our computer is running Windows 7 (64bit) - and the phone use to work fine.
We have tried using SDK tool, installing drivers manually when the phone is plugged in, but the computer will just say that it is already up to date, and it names the phone ' UNKNOWN DEVICE" and has the exclamation box next to it indicating it's malfunctioned. Sony software (PC Comp. etc) also will not detect the phone.
Have been trying to get this working for about 2 months now. 2 months of reading, google searches, more reading, trying idea after idea, and it doesn't work.
Has this happened to anyone else? Can someone help out here? Is this a firmware/software problem (maybe because it's been branded as a x10i)? Or could this all be a matter of the USB port being improperly fixed?
Facing same USB malfunctioned issue
I am facing the same issue since quite long since i have rooted my Samsung Galaxy 2 SGH T-989. My phone gets connected properly but when i try to transfer any of the files from computer to my phone. It gets disconnected automatically after copying the stuff till 5% to 10% and shows ''USB device has malfunctioned".
I am also trying to search and rectify this issue, but till now i have found nothing. Please let me know if you come across of kind of solution for it.
Im sometimes facing the that unrecognized USB but, everthing working.

I faced the exact same problem with my x10 mini. It wouldn't charge properly nor connect to my PC. I would have to wiggle the micro USB port and cable to get it working, which actually got me wondering if the problem was really the USB port. After I've bought a male-male USB to micro USB cable everything worked fine. Same thing happened with a brand new x10. I tried to use the USB cable I bought instead of the original one which came with the phone and you wouldn't guess, everything works fine.
So try to connect it with another USB - micro USB cable.

We have already tried connecting it to all of the (10) usb ports on our computer and we have tried NUMEROUS cables ( between my husband and I we have probably 8 cables, and have tired them all)
I'm in a quandry. I've had my Samsung Droid Charge for 2 years and while I qualify for an upgrade, I thought to myself it's time to root and see what this thing can do (and hopefully get some extended life out of it).
So I read thru a lot of root threads and how-to's, and was about ready to start setting up, went to connect my phone to my computer with the USB cable that came with the phone (which I have also used for 2 yrs) and lo and behold, there's no connection to the computer. Computer recognizes something trying to connect via USB, but notification on the computer that pops up says "USB Device Not Recognized." Now, when I used to connect to any computer, a screen on my phone would come on asking if I wanted to connect the phone as a mass storage device or media player. That screen doesn't come up any more when I plug in the USB. The phone beeps as if it was connecting but then just indicates that it is charging. I've never had any issues with this before.
I've gone thru the rigamorole of trying different USB ports, different computers, different USB cables. Nothing doing on any of those. Tried setting the phone on "ask on connection" and "mass storage" on different computers. Nothing there either. Tried with USB debugging on and off on the phone. No dice. I have even tried a couple of complete hard resets of the phone, and still will not connect to any computer. Based on some info from other forums I even tried downloading some Samsung USB drivers to my computer (which I never had before and had no problem connecting without), and they don't even seem to install properly. message I get when the install finishes says "Device driver was not successfully installed" and then just shows a list of my printer drivers????? My printers work fine - don't know what the hell that Samsung's Mobile Phone driver has to do with our HP printer.
Spent 45 useless minutes at the Verizon store yesterday only to have their "tech" guy give me the toll free number to Verizon and tell me it was their tech support number. Spent another hour on the phone when i eventually got to a tech support person only to be eventually told that I'm eligble for an upgrade.
Anyone have any ideas for me at this point? Frustrated by having spent waaaaaaay too much time on this already. I'd really like to go root, but I don't see how unless I can determine how to get this thing to connect to a computer again.
I tried different phones (wife has identical XZ1 and I have Nexus 5X), different cables (3), and different computers (linux laptop, linux server, and W10 desktop). I have USB debugging enabled. I have restart all computers and the phone multiple times. I've tried switching around the connection (even though I know it shouldn't matter) but I don't get anything on the computer acknowledging a connection, nor do I see anything on the phone.
Last time I know it worked was when I manually updated it back in August (flashing a mixed firmware to get fingerprint reader and Wifi Calling / VoLTE) on both mine and wife's XZ1s, so I know it wasn't that.
I don't know if I accidentally enabled/disabled something in the developer settings that would literally ignore connections to a computer.
I check the port and cleaned it a little, but I'm not sure that's the issue as the same cables tried will charge the phone no problem when connected to the wall.
Any help will be greatly appreciated.
