[Q] Computer dosn't recognize my device

Hello everyone,
I have a device problem, I can not connect it to the computer,
Every time I connect it to the computer it shows me just charging and nothing else and the computer fails to detect it,
I did a test with three different computers and other cable and I downloaded the HTC sync manager and still no change,
I made several attempts, each time under a different default (disk storage, htc sync manager) and still the same situation.
Has anyone already had this problem?
I would like if someone who has the device can check it for me and tell me on which settings his phone is connected, tnx.

anyone?

Open up Device Manager (Start > type in the search bar "Device Manager" > hit enter) and if you have a HTC symbol with a yellow warning icon that means your drivers are not correctly installed.
If you see nothing HTC/android related at all, it seems you either have a dodgy USB cable or a defective device.

Already tried that, i guess that my device is defective

If it's happening on multiple computers I'd say so I'm afraid

i bought my htc one x just today and i want to use htc sync manager, but i failed to connect my device with pc for sync. The htc sync manager window cant see any device! knowing that i am able to use file transfer but not the sync! how can i fix that? is it me who is doing something wrong or the device is not working properly!?

sometimes, disabling firewall and antivirus for a few minutes, before plugging the phone, may help. (I had this problem with Vista)

I have same issue actually. It just does not ask how to connect the device anymore and is just charging. I have to go to status bar and select HD so pc detects it.

I can't connect to my ps3 but its fine with my laptop.any ideas?

USB brick?

I'm hoping someone can help me here, and before people say it, yes I have done a search and tried different options but nothing seems to work.
I'm on 0.93 hboot with s-off and fully rooted for years.
The problem?
I was running Nikez Rom on my Desire and it had a few rebooting issues but nothing to be alarmed of. However after one of these reboots the phone did not charge, computer displays a 'power surge on USB' message and disables usb port. Fastboot is not recognised and fastboot USB does not appear when I connect. Using adb does not identify the device either.
What I have tried to do to resolve
Having read several forum posts around USB bricks and fixing fastboot to changing mtd0.IMG files, nothing has seemed to work. Alternatively, it could be me not following things or not doing things in a logical manner. I have also done a factory reset and flashed sandvold Rom but that hasn't helped either.
Help
I am now almost at the end of my tether (no pun intended), so would really appreciate some help in trying to fix this problem.
What I have not done
I have not yet flashed the stock ruu, but not sure how that would work either if my computer disables the USB port anyway.
Skill level
I'm not an expert so please be gentle.
Thanks

You are SOFF so the easy way to fix usb brick is to flash 4ext recovery since it has got an inbuilt usb brick repairer. However you are saying fastboot is not working. Even with usb brick fastboot should work. That leads me to believe that the problem may be elsewhere. I would check the computer once.

Thanks, tried 4ext fix usb brick option also, but did not work. I have a Sensation as well and that works fine re computer, so I don't believe it's a computer issue.
Also, the mains charger (plug) light goes off as soon as I put the Desire on charge but comes back on when I remove the phone from the mains charger - which leads me to believe there is something wrong with the phone usb software, but don't know what that could be.
Are there and other options for me to try? Is my phone usb bricked?

You can try the Unbrick option in 4ext recovery.
Also try on a different USB port or even a different PC.

Thanks - already tried these options.
Just responded above to a similar suggestion.
Any other help appreciated.

I dont think the problem is software related. I say this bacause the usb port is not working in either fastboot, recovery or rom. Each of these has got its own usb software and they cant all be bad. It seems to be hardware related. I got a feeling your usb port is fried. Most probably it has a short because your mains charger light is fanning out.

But could this happen while it wasn't connect via mains or computer?
How do I confirm this? Is there a solution if this is, in fact, the problem?

Pulled the battery out of the phone, out it on mains charge, but still main charger light goes off.
Tried another battery & it does the same thing. Tried different mains charger and it does the same thing.
How do I prove it's a hardware or a software issue?
Should I try a stock RUU?
Having read other forums regarding USB bricks, people have been able to access fastboot usb, but I can't.
So, I don't really know what the problem is.

I got fixed by this method.
androidforums [dot] com/desire-support-troubleshooting/485991-pls-help-stuck-cant-mount-sd-card-recovery [dot] html
check above link, replace [dot] 's with " . " (period)
boot to fastboot (back+power) and use the following command in command prompt
fastboot oem enableqxdm 0
This will enable the SDcard function in recovery
fastboot oem eraseconfig
This should fix the usb brick
reflash the rom you want from your recovery (you will need to wipe device via recovery 1st)

Thanks for your message, but the issue is every time I connect the phone to my laptop (and I've tried this on two different laptops), I get a message as below:
"One of the USB devices attached to the computer has malfunctioned, and Windows does not recognise it."
It seems the charge on the USB port of the phone has gone corrupt - if that's at all possible.
Once I get fastboot USB working, I'll be good to go.
I'm on BRAVO PVT1 SHIP S-OFF
HBOOT-6.93.1002
RADIO-5.17.05.23
Surely I can't be the only person to have this issue??

Also, I can access my sd card via ES Explorer.
On most of the usb brick issues, I believe the sd card is inaccessible. However, I can access it.
Therefore, I don;t even know whether my phone has a usb brick or whether it's something else?

Anyone?

I Think it is not a problems in the drivers because as i know if it is a problem regarding the drivers the PC must pop-up a notification saying unrecognized device, but in my situation there is nothing happened when i plug my phone to my PC the only thing that happened is that my Phone is charging.. my main purpose why i've wanted to connect my HTC to my PC is that i wanted to use the adb to downgrade and root my phone and also after that to change my rom.., do you have any suggestion to downgrade and root my HTC which i am not going to connect it to a PC ?.
Thanks in advanced men..

not a safe way to do it but if you feel like it you can try visionary. if the wrong drivers were installed then it may not pop up with anything, you can use certain applications to test if any drivers pop up (just google search)
otherwise try and clean out the usb port

I think u should try to change usb cable... might be bad usb...

Maybe you uninstalled the drivers? Have you checked it in windows hardware proporties?

actually i've installed it's drivers in my pc, and also my data cable is new.. i've tried it on lot of pc but still it can't be detected..

try to reinstall / update drivers from off site

i know silly question, but .. Did you try changing connection type on your phone ??

Just to confirm try using same cable & phone on some other PC, if it works there there's probably some crazy windows error on ur laptop which is next to impossible to fix, only solution is to format ur PC & install fresh windows. If you phone + cable does not work on other PC there probably something wrong with either, try using same cable on different phone & vice versa.
hope this helps

[Q] Need help with my USB mass storage

I just installed AOCP 6 on my HTC Desire HD but whenever I want to connect my phone to PC with my usb cable, it only recognizes it as charger and it doesn't show me any option to connect it to the PC. Is there any fix for this?

Phone not recognized by any computer

Not sure exactly when this started, but went to try to sideload the P update and can't get any PC to recognize my phone. Tried different computers and different cables. Won't even pop up on the phone to transfer files. So not an adb/fastboot problem. Last time I remember plugging into a PC and working was when I ran an adb command to enable the Hide Nav Bar app. Possible my USB port crapped out? Charges and fast charges just fine.
Any insight is welcome.
edit: Phone reads flash drive connected through USB-C adapter

1. Make sure USB Debugging is enabled
2. Try all USB ports available on computer
3. Try all USB cables available (OEM cable is always the best choice)
3. Revoke USB permissions
4. Uninstall & reinstall adb drivers, then reboot computer
If you have access to another Android device, plug it in and see if the computer recognizes that one. If it does, then the problem is your device, not the adb environment.

My phone with thru that. I had to unroot, re-lock bootloader, and i sent the device back to google. Since it was still under warranty and the issue was that the hardware wasnt allowing the device to be read via andriod auto or any computer. Not even my headphone dongle worked.

Can you do this through terminal app?

i have the same problem but even my fastboot mode isn't reconized. i can't even boot the phone. Tried unistalling and reinstalling adb fastboot phone drivers but it didn't work. I even tried 4 different cable, usb c to c, usb c to a... nothing working)!!!! I don't know what to do... and it's the first time in 10 years of modding. My devices show the red triangle.... will google refurb it if they find out that's modded?

if you are at the red triangle, you aren't in recovery, yet.
You'll need to hold the power button and tap the up volume key to get to recovery.

When my USB port recently crapped out, one of the symptoms was the inability to connect to a computer. Still not sure if it was hardware or something deep in the filesystem. A factory reset from recovery didn't fix it, but an RMA replacement under warranty from Google did.

Happened to my device too 3 weeks ago... the phone would sometimes charge, sometimes wouldn't at all, and wasn't detected anymore by my computers. Android Auto dead. USB-C -> minijack dead.
Had to RMA it, it was a problem with the USB controller or something

I had this issue as well I was able to fix by turning on and off USB debugging, still RMA'd it as I don't fully trust the port anymore. Not sure what happened, it was working fine on the way to work, on the way home I plugged in the USB for Android auto and got nothing.

This just happened to me too...think they are going to RMA but the phone is unlocked and I am not able to relock it anyway without connecting...

Was yours unlocked. I can't relock my phone cuz I can't connect to anything...I'm supposed to send in to Google but worried they won't honor warranty now...

My phone bootloader was not unlocked. I don't believe Google denies warranty coverage for unlocked phones, if the failure is not caused by it. They certainly never asked me any questions about it.
