Its general here so i think i can ask this kind of things so ,I m an IT guy that has run out of ideas. I would like to ask you some questions about a (probably hardware realted) problem that i have. All started suddenly , from one day to another all usb ports, camera and bluetooth stoped working. I dont really care about the bluetooth and the camera, the only thing i care about are the usb ports. I 've checked them with a multimeter (only the pins that provide power) and the strange thing is that they do provide power. If i connect something like a usb flash drive , the led flashes (stays on , doesnt flickers) but nothing happens. I am sure that's not a drivers problem because the laptop doesnt even recognize them in UEFI nor CSM. My UEFI does not have an option to completely disable usb ports, only to change from usb 2 to 3 (no change at all). I m sure it's now a power problem, i ve reseted the bios even by the motherboard jumper.So the question is , what it may be? is it a motherboard malfuction ? Can it be fixed? Also , is there any possibility that for example the camera is faulty , or the camera cable , and shortcutting something? (i mean if i disconnect the camera and the bluetooth, is there any possibility that it will be fixed? ) thanks in advance.
p.s. also on the motherboard there isnt anything strange like a blown up resistor or something.

Well for a while I thought my usb just died on my phone. I thought it got wrecked by physical damage like a power surge coming through mah pc when booting up and such...
But I just thought, well what the heck, and I flashed an old htc stock rom.
Now when I connected my phone to the pc, my touch pro gave me the 3 option screen.
activesync,sd,internet
But the pc did not detect any new hardware .
So I sadly flashed back to my energy rom. But al of the sudden when I wanted to connect my touchpro to the pc for charging, it asked me what to do (3 option scnreen), and the also detected my touch pro (well now my touchpro, it just saw something got connected).
So my pc tried ti install the drivers, it said it installed pockec sync usb something. But device center didn't notice any phone.
So I thought, too bad, but whne I disconnected the phone I heard a sound when disconnecting usb hardware.
Now the pc doesn't detect my touch pro when plugging in.
But this is proof it isn't physical damage (atleast I think).
Cause of the usb failure.
I was flashing a couple of months ago, when it suddenly started to stop at the middle. (each time it was another point so no damaged rom).
so I was able to flash it form my pc that time, but the times after that I had to flash from sd. Also when I tried to connect my phone, the pc lost connection with the phone after 40 secs.
Does someone know what to do? Please help me, usb is kinda important .
Btw, I have got this problem at every pc, also with every cable.
And now windows keeps saying an unkown device connected.
And shortly after windows detected my phone it undetects its.
(i hear two beeps in a row)
Yes I have disabled fast usb to pc
I forgat to mention that my pc doesnt reconize the device,
and with this rom my touchpro doesn't know it is connected
(It doesnt want to sync or anything), doesnt see it got plugged in.
Is there n1 here wich knows the solution??!
This problem is caused by damaged mini usb port on your device.
Actually this this new mini usb with 11 pin used in Touch Pro in & many other HTC device has a very delicate & thin plastic piece in middle. Quite visible from outside, this acts both as separator for the 2 layered pins of mini usb & base for connectors when u insert a usb to connect a pc or the audio cord.
This small plastic separator gets cracked if you do not handle usb connections properly.
Now here is the solution -
1.Remove battery
2.Look into mini usb port on device, see if there is a crack in between
3.If yes take a fine needle just press the cracked part so that the whole piece gets leveled.
4. Then you can put a small drop of quick drying fixer at the outer tip of this plastic part,take care it doesn't go inside otherwise it will create a layer on connecting plates.
Hope it helps you.
i rencetly bought the htc touch pro but when i connect trough usb on pc the pc does not reconize. it's not showing nothing on phone i try severel usb's and diferent pc's with diferent operating system. the phone charges but it not recognize. i only can syncronize trouhg bluetooh.
i did all the step's i find in the forum and in the internet. and i'm getting the same results.
Please anyone can help me ???? tnks.
Sory for my english.
Are you running stock or a custom ROM? I haven't had that issue(yet) but I am trying to help troubleshoot.
viBranZeOS-2.0-WWE this is the rom that i'm using. and i try alredy 2 other roms, and its the same.
I honestly have no idea what the issue is nor a fix/work-around. However, what I am attempting to deduce is if you had a stock ROM I wouldn't be of much assistance because I only run the ROM in my sig/signature, which is a custom ROM. Now, I'm not 100% on if your ROM has this option but I know the ROM in my sig has an option to change the behavior of the USB connection, from mass storage to active sync. What I am attempting to figure out is if one of those modes has been enabled and the registry is just not accepting or if the usb port is stuck on only charging. I have no clue on how you would find out as I've never heard of that ROM. By the way, what version of TP do you have, GSM or CDMA and is it a RAPH100, RAPH110 or what ever is showing above the imei behind the battery. You should see a bar code and just above that are four (4) letters followed by three (3) numbers. Let us know what you have and maybe someone else can chime in.
EnergyROM 29018 w/CHT2.0&.sencity this is your rom ??? i can give it a try. how can i see if is GSM or CDMA ???? my phone is RAPH100.
tnks in advance.
p.s i'v had the phone charging for 2 hours and it's only 2 risks. :s
Clarification: It's not my ROM but it is a ROM that I use most often. GSM/CDMA depends on your carrier/service provider. Looks like you may have a GSM device but I'm not a 100%.
Additionally, what happens when you turn off(shut down your phone completely) and charge?
well i'm using vodafone. and the phone is unlock from factory. it was that the guy told me. i am giving a try with that rom. whit the phone shut down and usb turn on the home buton stay's whit the light. i'n the 3 color screen when i conect the usb it's allways saying serial and don't change to usb.
Not exactly sure that is what I am asking. So do this for me: remove the battery, then put it back in and without turning on the device, plug in your phone to a charger(not USB cable) and tell me if you see an LED circle around the center button slowly light up and then disappear.
yes is that what it happens. and it happens this to with the usb plug in. whit the phone on or off.
So let me guess here, does it still take forever to charge from 30% and still get hot when the device is completely off and plugged in. If so, it still seems like it could be a battery issue to me. I don't know how to confirm if it is the device or the battery but I'd start there if you haven't already.
Additionally, if you are getting to the multicolor screen, then connecting the device to your computer and not seeing the change from Serial to USB and you've already tried changing the USB port, USB cable and computer then it is possible that your device's USB port is somehow broken(for the lack of a better word).

you are right i go the multicolor screen and not change from serial to usb. but i didn't try in other computers. i will tell you when i try.
good day to everyone. firstly, i would like to thank you for having the time to read my post.
well basically heres my inquiry, my unit is the alcatel tab t10. i never had any problems with it until recently, my device's usb port suddenly stops working.
tried unchecking the usb debug mode, tried checking it but to no avail, the usb still does not work. it doesnt seem to connect to my laptop. tried changing the cable.
i also tried connecting my device to my brothers laptop.
correct me if im wrong, but when the usb fails to connect to any laptop, their should be a notification in the laptop that the device is not recognized. but in my condition, no notification shows up. its like my device does not really connect at all.
oh and if it helps, i bought an otg cable before it started malfunctioning. but the only thing i had conneceted to my device is a wired mouse and a wired generic gamepad, which both seems to be working perfectly fine.
also, if i connect my device to a wired mouse, it would work perfecly fine. i could also connect to a usb flash drive, that is via the otg cable.
so whats weird is that the usb cable does not work, but the otg cable works fine.
if you have any question or any suggestion , i would truly appreciate it.
Hmm.....well the good thing is the port itself isn't "dead" as you can still utilize it for OTG. My only suggestion is make a backup of all your apps and data and try a factory reset.

thank you for the suggestion guitarman2010. unfortunately my usb port isnt still working. i also reflashed my device's current firware. but still wasnt the solution i was looking for. i was just wondering if there is a directory under the root folder that holds the devices usb driver? would it be possible that the device's driver itself got deleted? i wam still at awe that the otg cable still works like a charm.
and another thing, is the male usb pin the same with the flash drive's pin? cause if i connect the usb cable to the otg cable it wont work, but the flash drive works normally.
sorry for the amount of question im posting
thank you very much for the suggestion. especially when u told me that the port itself wsnt dead. i can now breathe easier..
and future suggestion and advice would be appreciated.
do you guys know how to access the phoneutil in tablet? maybe i should change the usb option to pda? but i heard that its only applicable to samsung 4.0.3 devices? suggestions are appreciated.
Hello, I have a problem with my MK809IV stick. It seems to be a hardware problem or a feature of my device, maybe you can help me. I can't flash any rom to my stick, because when I plug it in my PC, I have a message "USB device not recognized". I tried different methods, such as pressing Reset key or making contact between 8 and 9 pads of NAND - no result. At first case I can see an Android picture on the screen (sure, if I connect it to TV), at second case nothing really happens: even CPU stay cold, no picture on sreen.
As I know, it's a problem of devices (not only MK809IV), which have PCB, marked CYX_809III V5_0 20140510.
Please, help. My device works bad, there is a low FPS in films, and I can't flash any ROM. I spent a lot of hours trying different methods and searching for information.
Same here
