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.

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.

Mine was working until I booted into recovery. Drivers got installed automatically and now I can't connect my phone to my PC again : /

[Q] USB Mount THing Wont Work

it charges via computer and all that but it wont mount the sd so i can copy/move files frokm computer

Which Rom are you using....some of them are having USB mounting issues....I know one of at least one cyanogenmod nightlies is having issues from putting mexdroid or whatever it was called on my phone so I assume some more of the nightlies have issues but that is just an assumption. So yea that would be my best guess.

Need to know what ROM you're using, and did it work before you made any changes or has it never worked?

its stock rom... http://forum.xda-developers.com/showthread.php?t=836042...i downloaded the odex

when you connect your phone to your computer, drag down the notificatiom bar and select use device as "disk drive". this will mount your phone as you wish as a storage drive which is what allows you to use third party programs like doubletwist. there is also other options like pc sync and charge only, which is what you are stuck on.

thats the problem...it wont show anything on the notificationbar as it is supposed to...is there other ways i can reinstall original rom??

Im using mexdroind! And on mine in Windows 7 it shows all the drivers but my phone pops up as a MTP device??? Why is tthat and how do i fix it?

I think it could be your USB Debugging Mode. Enable it on your mobile.

I also would lke more info on what MTP device is.... and how to install the driver for it... cause I am hoping that would be a work around to solve the usb mount problems on flippy125 kernel untill he releases a new one... btw you can flash a different kernel like pershoots and it should go away and work fine..(then flash back!) Lol
Or just mount usb via recovery...

Problem:- File/Data Transfer via USB

Ok I have a problem with file transferring on my HTC Desire.
Whenever I use my Desire to transfer files FROM PC to Phone, it will always pop up delay write fail [On my PC] and my phone will start glitching, one time it freezes and will soft-reboot. Also, the file will not be successfully transferred to the phone. The file size shows the same as previous but it's not complete.
Been having a problem with this for awhile.
I have really no idea how to solve this.
Suggestions?
Attempted both normal USB Disk Drive mode & Multi-Mount SD widget. Both will give the same issue.
Current ROM: CM 7.0.3 - using 2.35 based kernel of ManU HAVS-AXI-CFS
PC: Running XP SP3

This problem also occurs while transferring in Recovery.

U have a usb brick there's a link for the fix in the every thing desire thread in desire/Android development

But it works the 2nd time..?
It's like, the transferring is choppy. Slow and then delay write failed and phone hangs
After that, trying again, it works, sometimes.
But I'll try it now.

Problem ceased to occur now but transfer speed is below par.
On CM7 .3 version
I'm using ManU .35 based kernels, it's still slow.
I'm using Multi Mount app, it's also slow... advice please @[email protected]

is your problem same as mine as per my thread?

[Q] Upgraded to Leedroid v4 and cannot connect to pc

Hi,
I've searched all over and cannot finf an answer to my problem??? I have just upgraded to Leedroid v4 and everything works beautifully except I can no longer connect to my pc. It is recognized in device manager but the phone doesn't come up with splash asking how I want to connect it, and so I can't use it as a disk drive. The phone still charges though? I have tried ticking and unticking the ask and usb debugging options.
I don't really want to flash back to an older rom but if that the only way ill have to, can anybody help please????????/

I'm sorry, there is no way in hell you have searched all over. It's one of the most known bugs in the version 4 beta from Lee. It's on pretty much every page in the dedicated thread.
This is what you do. Either download Auto mount from Market OR change kernel to Unity's or Lord's. Both those kernels have fixed the USB connection problem.

Thanks for that. I searched the term not connecting to pc on this forum and google and didn't realise it was a mounting thing!

Np mate. You are most welcome.

i Too was looking for the same thing. Thanks a lot mate

The kernel was updated by Lee, you can try the new one from his thread (see my sig). New rom version should come this week.

USB connectivity issues

ATT Galaxy S3
SGH-i747m
4.0.4
kyanROM 1.3
I am currently unable to connect my phone to a PC or MAC using the usb cable. I have tried just about everything I can think of with no luck.
what I have tried so far is:
restarting my computer and phone
different computers mac and pc.
different usb cable
uninstalling and reinstalling samsung drivers from PC
tried switching from mtp, to ptp, to adb, using phoneutility (*#7284#)
pulled battery
wiped cache partition
fixed permissions
I even booted the phone into download mode and connected to odin.
I see nothing.
any ideas? I am at a loss. I cant find any info or similar case.
edit: i also tried downloading kies and using the connection troubleshooting utility.. no luck
usb debugging is on but tried with it off as well.

I've been having the same issue on my Win7 home premium.
The phone is charging but can't see folders.
It works on OSX as a Camera though.Click on "Connected as a media device" from the pulldown menu and select "Camera", youll also need a program on OSX. Go to
androidDOTcom/filetransfer/ (i'm under 10 posts so probably can't post links)

Part of the problem is I am never getting the "connected as media device" message.
the phone only charges when connected to a computer...mac or pc

Try using a different usb cable. Something pretty short. I've had many a cables stop working. Also try a different USB port on the computer.

I have tried about 4 different usb cables on 3 different computers.
2 pc one mac
some of these cables I know for a fact were working at one point.
I am thinking it is my phones hardware at this point.

did this problem started since you flashed Kyan rom 1.3 cause I had the same problem a few weeks ago and I recently flashed the latest CM10 rom and everything works fine now. Does your phone charge when you plug it?.

My phone charges when I plug it in.
I can't be sure if this only happend after I flashed kyanROM 1.3.
That is definitely something I did since the last time it was pluged into a computer.
Maybe ill just flash cm10.

it looks like a driver issue to me! do you Have the snapdragon toolkit install on your computer? If not you can find it ther: http://forum.xda-developers.com/showthread.php?t=1746665
try the first step uninstall your driver and then install them using the toolkit
If you are using your front usb port try switching to your back usb port sometimes devices don't like the front usb port

Sounds like it may indeed be a problem with the phone's hardware. You might want to try taking it into the store to see if they can reproduce.

i re-flashed my phone using an old backup from when i knew usb connectivity was working,
still not working.
Brought the phone to an ATT device support center while on stock rooted rom.
They didn't realize the phone was rooted and they couldn't re-flash my phone without usb connectivity so I got it replace.
I am going to run stock rom for a bit... maybe until the official jelly bean release.
then maybe ill go back to Kyanrom or cm10... any suggestions?
Ilso I am not sure what created my usb issue.
I think it was my regular use of an old iPad power brick.
I am going to only use the stock charger from now on and hope that problem doesn't come back.

Had the same problem, but my work machine has never once gave me a problem, the one at home does this exact same thing, it maybe a phone hardware problem if you see it doing it on another machine, but I dunno, only reason I haven't fixed the home issue is, I do NOT want to re-install win7, my linux box see's it perfect every time also. I read somewhere in a forum, that it is a samung/microsoft driver bug. It is stored in the registry somewhere, what I saw was I had it working perfectly, then I plugged in my MyTouch to push a stock rom onto it, and then the next time I went to plug in the SG3 the problem started. Windows acts real stupid when you continuously keep plugging in different devices all the time. But then again, you said you tried it on a mac. Humm! Again, this is my opinion only.

same problem i have with no solution need help also please
same problem i have without any solution i need help please

Had the same problem, but with a brand new SGS3 with the stock ROM and cable. Plugged in my Nexus 7 cable instead and that works for some reason. Will bother best buy about it I guess.

got the same issue. tried to sync some files over from the gs3 to my laptop and it only charges the phone, does not recognize it . tried several cables and tried on my desktop, nothing. now im in search cuz this kinda sucks. i flashed CM10 ROM2 and it stopped working for me after that, tried restoring back to rooted stock TW but nothing still. still looking for a fix.

One thing I noticed is that all the computers where I'm having issues are running win7. One win7 home premium and the other win7 pro.
In the office I have XP pro and it recognizes the phone with no problems.
