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.

[Q] G2 not being seen by PC

Hey guys,
I tried getting some help for this over at the Nook Color threads because it all started *after* i rooted my NC, but no one's been able to explain to me what Ive done wrong or whats happened...
So here's the sitch.
o I have ADB installed, but it only activates in device manager when the nook is plugged in, not the G2
o When the NC get usb'd to the PC, it fully registers and gives me access to the SD card on it
o .... where as the G2 just sits there and says "yay im getting power!"
o ,,,, BUT if i plug it into a HUB rather than directly into a usb port on the mobo or front, the PC (win7 x64 ult) seems to see it but doesnt know how to properly assign a driver to it and gives it UNKNOWN
o also i checked the usb-adb ini file, and it lists all my other devices in the hardware cues BUT the G2, which means it hasnt properly registered since then or never had a proper profile to begin with in the PC. It even has my older mt3G listed which I havent plugged in since all this started.
Ive tried multiple driver types, but literately, NOTHING has worked. Its like the G2 isnt even properly registering in the computer when connected. I tried a factory reset, but still no luck. Is there anything beyond a soft fact reset for an unrooted phone? I mean, i need COLD AS STONE back to day 1 reset.
Please help, I really want to root this :'<
and no, the only way now to access my sd card is to turn the thing off and use a reader. Like i said, it literately is NOT seeing it :<

Wrong section. Ask in the Q&A, not the DEV section.

Try installing HTC Sync, even though it doesnt work with the G2 because its sense based, it will install the proper drivers for you. This worked for me.
Heres the link:
http://www.htc.com/www/SupportViewNews.aspx?dl_id=1058&news_id=804
Another method would be install pdanet on you phone fron the Market, then install pdanet for your computer from here and it should install the drivers when you plug your phone in with pdanet app running:
http://www.junefabrics.com/android/

I tried the Sense link, but I couldnt find the download option for it.... anyways, heres a more precise description of the issue
When I go and install PDA Net, it loads up the drivers, but the computer literately is not even registering that a DEVICE has been plugged in via USB. I dont even get the USB connect prompt on the phone!
That's what Im saying, something is up. I need to take the cable with me and try this on another computer now that I think about it to rule out that something isnt damaged on the phone...

What ROM are you using? Gingerbread ROM's act like the (for now), at least from what I understand. I tried CM7 and sure enough - it acted just like what you're describing.

But thats the whole thing, im not using a ROM, its just the stock OS build. if i was using a ROM, id have tried removing it and reloading it, but this is on a phone that isnt even rooted yet... actually... should I try going temp root again and see if that fixes anything?
Whats the best way to do that now since I keep reading Vision got pulled away because it was damaging phones or something?

Okay, so i tried plugging it into a diff computer.... same result... so whatever it is, its the phone.
Any ideas XDA pplz?

Has it seen the g2 before? if so, get usbdeview, find the drivers in there that would be used for the g2, delete those. Snag PDANet and download that, plug the phone back in and see what ya get. You will get the pop ups again about the new software being loaded since it will have to find and reload drivers for the phone and PDANet will have the drivers you need.

Like the guy above me said, DL or re-DL the drivers (though none should be needed if you're using it as a storage drive, the comp sees it as a usb drive). Is it charging your phone when you plug it in? It's rare, but the USB cable may be bad.
The only other thing I can think of is that something went wrong and the phone isn't releasing the mount to the sdcard, in which case you should try rooting and using a different ROM or a stock rom and it should help.

Well thats the whole thing, the computer doesnt even see the USB part of it. Thats been my whole issue. The computer doesnt see the phone or the usb drive part. It straight does not see the phone at *all*! Doesnt even show up in Dev Manager, but yet it gets power. I even went and got a new micro USB cable, fresh, and still nothing.
im getting to 86 the os and reload Win7, im like super uber pissed over all this because i cant figure it out. I dont even know whats wrong >_<!

Just for kicks (because I had this exact thing happen to another phone of mine - the slide) you're rooted, which means you have clockwork right?
Reboot into recovery and go to the 'mounts' part and select 'mount usb'. Do that with it plugged into your computer and let me know if the phone shows up then. That's the only way I could put it in mass storage mode. I flashed something other than cyanogen's rom and BAM, it worked like it was supposed to (Linux did mount cyanogen though - weird).
If you want to go back to 0 day with your G2, search 'PC10img' and download it. DO NOT FLASH IT YET, you could really screw up your phone since you have s-off. Go to the wiki and scroll to the bottom, it tells you how to get s-on. Once you can verify that you have s-on, proceed to flashing the pc10img.
Wiki

Okay, so, Im way better now. Apparently I managed to get s-off and root ability via
http://forum.xda-developers.com/showthread.php?t=837315
when i reloaded and got rooting ability, somehow, I now have a detectable sd card again.
I dont know how, I dont know why, I just know that Im going to throw CM6.1.1 onto this thing and be rocking it hard
Thanks again for all your help guys, it was awesome to know XDA really helps out its followers
EDIT:
Okay... so now Im mixed. I have a rooted phone, with CM6.1.1, but still doesnt properly recognize when plugged into the PC.
oh well, I already called TMobile and their sending me a new phone under warranty. Its gotta just be a busted port in some way for detection. I dunno. >_<
But still, thanks a lot guys. Means a lot

Won't Connect via usb, dosn't detect phone or computer ?!

My phone (HTC Desire) used to work fine (i have had it for nearly a year now) but now it has suddenly decided to not let me connect, sync or do anything over usb, none of my pcs detect it either.
I have tried a hard reset (no change) and i am wondering what I should do next?!?
Many Thanks
Josh
p.s Phone info in signature
EDIT: It just wont recognise anything via usb except charger and car dock :-S

as your phone seems not to be rooted, you should check wether the drivers are correctly installed if using ms windows...

The drivers are correctly installed, I just don't know what to do next ...

You should try rooting (with Unrevoked-it's kinda' easy) and after that installing a custom ROM ... and try then
Or you can try another PC and see if the sync is wirking there

the problem is that i cant root without the usb working!
I have tried multiple pcs...
also do you think that t-mobile will take it back and fix it? (its debranded no noticeable change except boot screen)

Sounds like u may be misc ****ed/usb bricked.
Does your sd card detect? if you mount it does it have qxdm files on it?

Try the gold card sollution ... maybe u'l succed
Ps.warranty is voided just when you root you phone as i know

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.

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.

[Q] Problem installing D2EXT+roms?

Hello,
I have just formatted my SD card correctly to use the D2EXT+ roms that are available.....
I flashed the D2EXT+ hboot from CrystalKingdom v0.3.1 and installed the rom yesterday and everything seemed to work fine apart from the weather where i was getting forced closed, i also tried Alex Vs rom and it installed but i had constand forced closures.
I tried today with CrystalKingdom latest rom and once installed i get display issues....the lockscreen is just a white square and the HTC cloch is just white with no details, also my apps have very big writing that is messing up the screen.
I obviously must have missed something.
Could someone help me out please?
Edit: I i aso have USB brick now....CAn someone point me to the latest easiest way to sort this now please and how do i find my cid?
I am S-Off
Thanks.

I flashed this rom again a third time and it has loaded up with no problems....don't know why?
But i have a USB brick.....i am trying to use Android flasher to fix it but i can't get the cid.....i followed a guide to get the cid using astro file manager but thats too big to use with android flasher.
Can some one give me a step by step guide, the old tutorials seem to be very mixed up now.
I have flashed back to CyanogenMod-7 now so maybe i can fix this with the terminal emulator?
Appreciate any help.

I am going to say that the first booting time of every Date2EXT rom should be a little long.
If you see something was force closed at the first booting time, just click "wait", "wait" and "wait"!
I used to have the same problem with you ,and Alex told me this way and everything solved!
Er...
I don't have any ideas about how to fix your USB brick, I am very sorry for that. Do you mean you can't link your phone to the computer at the bootloader? or at the android OS? Can you push your files to your phone through the USB line?

Thanks for the reply I will try that.
About the USB problem, I cannot connect my phone to USB though android OS, USB debugging or USB options do not show when enabled.
