USB detection when connected to computer not working!(*POSSIBLY FIXED*)

- I think I found a fix and it was quite easy to be honest. All I did was reinstall HTC SYNC and my computer is recognizing my phone now. Only thing is, i'm pretty sure if you want to use adb you had to uninstall this.
- Another solution is to update the RADIO on your phone to the newest version. (CREDIT GOES TO HAZAKINS FOR FINDING THIS)
I successfully rooted 2.2 today with the new guide. The first rom I flashed was RevE and noticed that when I plugged in my usb, to my computer, the notification bar would show up with the option of mounting or charging and then disappear after a second. Not only that, the phone didn't charge at all while connected and the notification bar was clear and didn't tell me whether I was charging only, ect even though it usually does.
The only way I am able to access my SD card is strictly through recovery now by mounting the usb. Other than that, there is no other way for me to access my SD card. Let me be clear that YES I have tried more than one USB port and usb cable but still there has been no luck. Let me also add that it was working fine before rooting.
Also, I just flashed to CM R2 successfully and the same issue still exists. I'm not really sure what else to do.
One interesting thing, if this means anything, that I found, was that I saw the My HTC drivers in device manager only when I accessed my SD card through recovery, it never appeared when I tried to connect my phone to my computer outside of recovery.
So, I'm not really sure what else to do. I have rebooted both my phone and my computer and I am really leaning towards the fact that it may have to do with the My HTC drivers. The thing is though, add or remove programs doesn't show My HTC when my phone is connected to the homescreen. But, I did manage to uninstall it while in recovery mode and as soon as I went back to the homescreen the driver installed so fast that I couldn't stop it from installing.
So, I have no idea what to do

I just confirmed that I am not the only one with this issue in IRC. We both narrowed it down to the driver being the issue. I'm not sure how exactly I can delete it though because it only shows up for an instant and then disappears. It isn't even in add or remove programs.

When you connect your phone, try toggling the USB Debugging off and then back on. I had similar problem (not exactly the same) and this is what worked for me.

I actually had this exact same problem... all the way up until I tried a different usb port... so I guess I got lucky.
But the one port was working fine up until I put the new ROM on it. Then it stopped working. Then I had to use a different port. I was able to do that... But now after phone reboot and PC reboot, 1st usb port works fine.
I hope it starts working for you.

I did same thing having same problem, I even downloaded another rom with rom manager and installed it, still same problem. When I plug in my USB cord it will pop up for a second on the phone to ask my charge or drive the goes away before i can do anything.

basically sums up my issue.

OK Here is the fix, buy a mini sdcard reader copy the pc36img file to your sdcard using this reader, install back in phone boot into recovery and let it update, then startover root process, this worked for me, I haven't update to 2.2 yet, but I got usb back

Did you try this? Simple fix.

My fix was to get rid of the extension USB cable extender I was using. Apparently the signal degrades too much across it. I tried 3 different extender cables too.

I tried that, it was a no go.

I had the same issue. Using Unrevoked states to uninstall the HTC sync drivers. Just reinstall them and it should charge your phone. That worked for me...

I did that, twice, and the same issue is occurring.

Also having the same problem after the 2.2 down grade.

Same problem
I can't mount my SDcard either. I followed the new video tutorial to get root on phones that came with 2.2. I think something went wrong when i got that out of memory write error. I have tried two different computers and all their usb spots. I have not been able to mount sd card yet. It does charge however. Any ideas as what to do?? Oddly enough i was able to get Amon-ra recovery flashed so doesn't that mean i have full root??

Seems like a good amount of people are having this issue. If someone comes across a fix please share!!!

Try uninstalling My HTC and HTC Installer Drivers (I forgot the exact name) and then reinstalling HTC SYNC.

Got mine to work
on some other forum someone tried flashing the radios to the newest version and fixed the problem. I tried this as well and came back here to let you guys know that it worked for me also.
here is a link to the radio files.
link::::forum.xda-developers.com/showthread.php?t=715485

Easy fix: Uninstall the HTC software, then reinstall it.
This should reinstall the driver for your EVO.

the HTC software uninstall and reinstall didnt work for me. Wish it would have.

My phone isnt recognized by my computer anymore

Hello,
i've got a problem like the title says. Everytime i connect my phone to the computer via usb, i get the message the device wasnt recognized by the computer. i tried everything i know, another usbport. etc. i want to install a new radio, but without connecting to the computer it isnt possible, because i dont have the usb debugging active.
i hope someone has an idea what i can do. i have rcmix 6.1.0.1 installed.

Are you using Windoze?
If you are unfortunate enough to be doing so then you might need to reinstall HTC Sync program (sometimes it works better if you completely uninstall it first including manually removing any left over folders and files in the application data folder.

thanks for the quick answer.
i tried it, but it didnt help. where is this application data folder? do you mean on the computer? i found after uninstalling no more folders from htc.
and yes i use windows home premium 64bit.
got another idea? now it says also the device does not function properly. i hope that nothing on the device is broken.

yes he is talking about your computer... if in the "program files" you hasn´t anythink about HTC SYNC,, ALL IS OK...
but enssure that in the configuration panel-system-dispositive administrator you hasn´t any drive installed for your android device... if you have installed it, erase or uninstall it before re-install htc sync or the htc drivers....then you can re-install and reboot windoux...
and hey buddy!I recommend to you to consider to pass to linux, you will not have this type of mistakes... LOL
UBUNTU is great!

I'm afraid I don't know much about Windoze but memory serving appication data is a hidden folder so you will need to change it to view them and is in the Documents and Settings / [Your username] directory.
Device not function is just a default Windoze error when it can't install something, ignore it, your phone is fine.
If you have reinstalled HTC Sync, try a USB port on the opposite side of the PC. So if you trying ones next to each other on the front, try ones on the back (they use different headers on the motherboard).
If that doesn't work then I'm afraid I probably won't be of much more use, sorry.

thanks guys for your help, but although i followed your advices, except the one to switch to linux ;-), it hasnt got better yet. the problem is still exsisting and i dont know what else i can do.
anyone got an idea how to install radio without having usb debugging and the drivers from the computer?

Hi!
I've got the same problem with 2 different PCs, one with Win7 64-bit, the other with Win XP PRO.
Other devices work fine with the same USB ports, so i doubt it's windows or the PC...

you can´t flash any radio if your phone is not recognized
well.. Let's continue with the problem in question...
1.At some time could you have connected it?with the stock rom maybe?
2.have you tried to swich on mass storage usb mode?what´s the result?
3.when you tries to swich the phone for flash some radio you enables "usb debug"
and "only chargue"?
its a weird problem

Hey man, I've had the same problem with my old Desire (normal). Which was actually broken.. Went back to the store twice and it was sent to htc twice. But that one wasn't rooted tho. But in the end, the sensors were broken & something inside the phone that didn't recon the pc. But also try a full wipe, which helped temporarily for me.

1. yes i functioned, not only with stock rom, but also with the next few custom roms. but then 2 weeks ago the problem occured and i dont know why. before i used custom roms for months.
2. it also doesnt recognize the mass storage anymore, i dont see the memorycard as a storage device in explorer.
3. yes i turned usb debugging on and connected charging only, i flashed radios before. but the problem with the actual is, that my signalstrength is weak and so i wanted to flash the recommended for this rom, and so i recognized there is something wrong, cause my problem here occured.
normally i sync with myphoneexplorer so i didnt realize that mass storage didnt function anymore.
and because earlier i got no problems, i think more and more, that something on the phone went wrong.
maybe it helps if i go back to stockrom and undo all changes i made, to start all over again?
again thanks mate for your effort to help me out

you´re welcome companion
i reded in a spanish forum ( www.htcmania.es ) about your problem and there´s people that had the same problem with a S.GALAXY S & desire HD...
someone was solved it fullwiping and formating (in the paragraph of mounts & storage into CWM) and flashing another ROM... then they formatted their sd card with a card reader OF THE PC... later they was formatted the sd card from the pc and the problem was disapeared successfully...
BUT if it persists i think that you should (mi suggestion) send your machine to the thecnical service....

ok, will try this today evening when i'm home. if this doesnt work i will reset it in the orginial state and send it to the technical support. i will leave a comment if i was successful, perhaps this will help others with the same problem.

USB cable charges the phone, but doesn't connect to PC

Hi.
I've been using my HOX for about 2 weeks and it's currently running ViperX 1.0.1 with the latest Faux 004 Beta 7 kernel. The problem I have is that, when I connect my HOX to the computer via an Micro-USB cable (either the one that came with the phone, or another Micro-USB cable) the phone just starts to charge and it doesn't prompt what type of connection I want to use (Only charge, file transfer etc).
The setting that it should ask for a connection type is turned on, standard connection is set to "Only charge" at the moment (but I have tried every other option also), and USB debugging is turned on as well.
The computer doesn't recognize storage device either, and HTC sync can't find the phone. I've tried to restart both the phone and computer, re-install HTC sync, clear Cache and Dalvik, uninstalling the backup app I'm usually using and also SystemTuner by 3C, but without any better results.
This is the first time I experience this problem. It started to behave like this yesterday. Everyday before that, it all worked as intended :/ The only thing I remember that I've done is to update Faux kernel to Beta 7 (from Beta 6) and installing SystemTuner which I didn't have installed before.
I have tried three Micro-USB cables, several USB ports on my computer and also other computers. So it's something with the phone I suppose.
I read somewhere about another person having this problem and someone told him it could be because "fast charge" is enabled in the kernel. But from what I've understood, the Faux kernel I'm using doesn't support fast charge option.
I'll be very glad for every help possible to resolve this issue, thanks!

Settings - connect to pc
Have you checked that "ask me" is on? Otherwise it uses the default mode which is usually "only charge"...
Edit: oww you tried that already... I don't know then... Maybe you should test it with the older kernel

Thanks for the reply. Ye, I've had that one enabled all the time. I guess I should try using the older kernel and see if it works, then I know what caused it at least
I will do that and come back here and tell you all how it goes! Since I can't transfer the file over from the computer to phone, I have to download the file directly from the phone, so it takes a little longer.

Okay, so I have now installed the "old" kernel that I used before and that I know worked (Faux 004 beta 6) but it still doesn't work, so I guess it's not anything associated with the kernel.
Any more ideas what I should try? I guess I could try restoring a previous backup from when I knew it worked, but I will probably only do that if there's not any other way to fix it - as a last resort.

Your phones usb connector could be broken or just dirty...

I tried to search even more about other people having this problem but couldn't find any real solution to it. So I did a Nandroid restore to a date when I knew it worked, and now it all works fine again!
Not sure what I did to make it not work, but if it happen again, I will try to remember what caused it

Works after a nandroid restore. But ye, I guess that could be a reason some other time in case it suddenly stops working.

[Q] USB No longer recognised

Hey guys,
Just last week my Nexus stopped connecting to the PC. First it wouldn't even charge or show the phone in explorer.
I tried bending the connector back up and it started charging again. But it still won't connect in explorer.
Drivers shouldn't have changed but I've tried reinstalling and still nothing. Tried different cables, nothing. Tried different ports, nothing.
EDIT: I was trying to avoid it but I've tried a factory reset and reflash of PA2.99... still nothing.
So I'm a bit stuck right now. Anyone have suggestions?
Have tried searching and the like.
On a different note, possibly related. I bought a Nexus 7 today and tried to unlock and root. Fastboot drivers aren't working. Tried several different packages and methods. No dice. Followed instructions etc.
Thanks
Jenkss

linux/windows/mac?
can you see your device in 'fastboot devices'?
can you see your device in 'adb devices', while running android or a custom recovery?
check if there's an updated version of fastboot/adb (not sure what OS you're using)

There seems to be quite a large percentage of these phones where the USB port breaks down. Mine was one of them. I had charging issues and my PC didn't recognize my phone. I still had a guarantee and I had it fixed.

64bit windows 7.
Tried with the latest adb/fastboot drivers.
Not recognized in either. Doesnt show up in any device manager.
The only way i know the phone has some form of connection is that the charging icon comes on.
Starting to think its the port that's broken some how. Bought the phone online back just after release so I doubt I'd be able to get a replacement.
Using airdroid at the moment to backup and transfer files around but thinking I might need to think about a new phone soon.

I'm sorry to hear that, but IMO, yeah, i think you should start looking for a new phone. Don't keep valuable data on this one.

Same issue here. I just UPSed mine to Samsung under warranty. They better fix it, since it's their hardware issue. The phone support kept telling me they were going to reflash it. Good luck doing that without access to USB.

Unable to connect as MTP after changing a USB-C board

Hi all,
I had a problem with my mi6... My dougther was cycling, and drop my phone. Something happened then, and the phone wasn't charging any more with cables... works only in one stand...
So, I've bought a new board, in aliexpress (https://pt.aliexpress.com/item/Carr...110.html?spm=a2g0s.9042311.0.0.3da2b90awX1ker), installed, and the charging is ok.
But now, I can't connect any more... I believe I have to reinstall all the system, but without a cable is too dificult to do all the backups...
Any tips?

Hi,
I've had the same issue as you, and have yet to find a solution. Check out this thread I made with everything I attempted to do to fix this problem.
https://forum.xda-developers.com/mi-6/help/phone-charges-connected-to-pc-t3884228
I also thought that changing the connection port would solve the issue but it didn't. Although I bought a cheap non-oem version. Maybe this has something to do with it ?
If you have linux, you can look into KDE connect to transfer files from your phone to your PC. That's what i've resorted in doing. It's not an ideal solution (can't update my rom) but it's better than nothing. I think you can make KDE connect run on windows PCs as well.
Best of luck !

I'm still trying to fix it. My problem is the computer is looping as soon as I connect the cable on the USB. Seems to me some driver problem.
I need to connect, but also need to be able to connect on TWRP. I also tought tha could be a driver issue, and guess that if I update the ROM, it could be fixed.
am I wrong?
