[Q] USB not connecting to PC

After unrooting my phone to take to Verizon for some repairs, I can't connect my phone to a computer. I haven't connected my phone to a computer since I rooted back in March. And you don't need to connect to unroot.
I read somewhere that upgrading the radio will fix it but I'm not rooted so I can't. All I want to do is root again and I cannot. My mac doesn't see with osx or bootcamp, it and neither does my Windows 7 desktop. It's not that it's unrecognized, my computers just can't find it.
Is there some fix that I'm just not finding? Or is my USB port fried? I've tried another cable as well.
I can still charge so idk. I'm at a loss.

I had something similar happen to me the other day. I upgraded the hard drive on my netbook & then did a fresh install of Windows 7 Ultimate x64. upon getting it up & running, I plugged in my phone and it just said "USB device not recognized".
Seeing as how I ocassionally do wired tethering with PDAnet, I loaded PDAnet on to the netbook & then it specified to disconnect my phone & asked what manufacturer phone I have. I selected "HTC", it installed HTC drivers, then asked me to plugmy phone back in(with USB debugging on), then it said it was installing my phone and everything went smooth from there.

Right, but I don't even get "Unknown Device" or "Device not recognized". Absolutely nothing happens.
My phone will charge but neither device talks to each other.

you ate sure igs a USB 2.0/3.0 and not a 1.0 jack?
czn you trhy on someone elses pc?
normally wjen a USB jack goes out that's it.
sprryfor typos, lpud music and alcohol. id say what else but domt want some law enforcement type to see my post. weee

Have you tried loading hboot then connecting?

Have you tried uninstalling your USB drivers, I had this happen and after a reboot it worked once everything loaded back up, search for a tutorial or I'll post when I get home

that *might* work.. if your PC is a store bought system, you'd just go to the manufacturers website and download the drivers from the 'downloads/support' page, then uninstall from device manager, reboot, re-install(and possibly reboot again).
if it's a custom PC, you'd goto the motherboard manufacturers page & do the same thing. if you don't know the make/model of the motherboard, it will also tell you in device manager(or just remove the side of the case and look at the motherboard itself, it'll be labelled somewhere near the cpu).

If by loading Hboot you mean loading the bootloader and trying every single option (even Hboot USB), then yes.

I can't even get the computers to recognize that I need a driver or that I have a device connected.

not sure if you've tried another USB cable or not, but if you have and it's still doing the same thing then it has to be a hardware related issue. possibly something wrong with the USB connection on your phone.
Awhile back, mine was doing something weird where when i'd plug it in to charge it and it kept showing that it was constantly charging, then not charging... I thought "what the hell!?".. I ended up trying canned air and it helped a little.. but started up again. I finally used some 'electrical parts cleaner' on it and ever since it's been functioning normally again.

well, in the time I've had my TBolt, I've tried out every radio & countless rom/kernal variations. I have never had an issue connecting to PC on any radio so I doubt the radio has anything to do with your issue.
You have already attempted everything else though(a side from the cleaning) so i'd wonder if there's some sort of issue with the software on your phone.

I have had this exact problem.. have tried different PC's, different cords, different usb ports...I have tried to mount under CWM also. Computers don't give any indication that there is anything hooked into them....the phone does charge however. I have reinstalled the ROM (using CM7.1.1) I have intalled previous backups which had no problems linking to my PC. I have not tried to clean the charging port..will give that a go...I feel I will have to by a card reader for my pc to read the microSD. worked fine for 6 months, but then just quit. Posted this problem on android central...but no one could figure out a solution, thought someone here might have....last post on my AC thread from someone with same problem was told by verizon/htc to send it back for replacement...don't want to but might have to do this...love to have a brilliant idea before I do though! Can't post the link to the AC thread as I am a new registered user here..been trolling all year...but you can find it under the Thunderbolt Rooting. ROM's and Hacks area.....

I'm pretty sure no one has a solution to our problem. I've taken compressed air and cleaned everything and still no luck. It's just a question of how much they'll charge me for it.

[Q] Phone isn't mounting to computer, but will charge! Please help!

I've had my nexus for a while, soon to be going on a year and I haven't been able to mount it to my computer for, I'd say like 4-5 months? It randomly just stopped working one day. It'll still charge when I plug my phone in. I've checked NStools and fastcharge is unchecked. I've cleaned the port a couple times. I still can't figure out why it won't mount. I don't think it'd be a hardware problem either because it still charges. I'm rooted and my bootloader is unlocked, I've also tried tons of different roms to see if that was the problem. It won't even mount through recovery, but like sometime last month it randomly mounted one time and It never did after that. I've spent countless hours on google trying to figure it out. Can someone PLEASE help me?

go into phone and dial *#*#8778#*#* and check if UART is modem, and USB is PDA.
If it's not, that's your problem.
If that doesn't work, flash a different kernel

UART is "PDA" but whenever I select "Modem" it changes back after I hit the back button.
I also tried two different kernels. Franco and Matr1x.

maybe you have encryted your phone?

Same exact thing happened to me. U think its an issue with Samsung phones.

Uninstall all of your Windows 7 USB drivers. Reboot computer, and connect Nexus S using USB. I find it best to connect through CWM recovery, by mounting your USB storage. Let your computer install the drivers, and then enjoy! It should be perfectly functional after that.

It's only Windows 7 that it does that on. I've tried computers with Windows XP before too, and my school Macs.

Try this:
http://nexusshacks.com/nexus-s-hacks/how-to-install-nexus-s-windows-usb-drivers/

That happened once to me, then I realized I was using an "only charge" USB cable from a car kit I bought. Using the original cable fixed the problem.

[Q] USB Connection Won't Work

I can't seem to anyone else who has this problem. My TF700 is working great. However, today I decided to bite the bullet and install CleanRom. After unlocking, I realized that my computer can no longer see the tablet via USB. It is not an unrecognized device, just nothing happens when I plug it in.
I have tried two different cables on 3 computers, so I believe the problem is with the tablet itself. It charges just fine and when I plug the cable into the computer or unplug, the screen comes on (just like when you plug in the charger), so something is getting recognized.
I don't see any physical damage to the port, it looks fine.
Anyone else ever seen this?
Thanks,
Chris

So it was working previously?

It was, not sure how long ago though. I know it was when I first got it. I'm guessing it is a hardware problem, but not sure what to do about it. I honesly don't care all that much about it, but I would love to get TWRP on it so I can flash roms. I haven't seen a way to get TWRP on it without the USB or GooManager, but I can't run GooManager because I don't have root yet.
Still trying to search to see if there is a way to get root without USB, but I haven't found anything....

Chris,
See if downloading and installing PC Suite from Asus helps.
That might get the drivers working again.
Are your PCs win7?

Just a thought. I am not running clean rom but when u connect to ur pc try going to settings, storage, and and hit the 3 little dots on the top right. It should show some usb connection tab.

Thanks, I'll try the software install, but since the computer doesn't even tell me I have an urecognized device (nothing in device manager), I'm not sure that it is. I also already rolled back to stock ICS and also tried the storage settings to no avail.
I unfortunately think I have a hardware problem. I guess I'm stuck at trying to get it repaired, or just live without the USB connection....which I guess ultimately means no customizations. I can still flash back to the stock Jelly Bean using the factory bootloader and rom from the Asus site, so I may have to live with that.

Could be the cable. Sadly, replacing it is ridiculously hard.

I wish it were. I have a second charger/cable and already tried both cables on different PCs. Uggh.

Connect the tablet to a PC running Linux and run lsusb to see if the tablet is recognized (the vendor ID is 0B05) - just to sidestep any possible Windows driver issues.

[Q] Only my right earphone gives sound. how to fix?

Dear xda members and administrators,
since one month my left or right earphone ( doesn't work anymore when I plug it in my asus eee pad tf101. Yes i did test my earphones at other devices and they worked correctly on those devices.
My question is how can I fix this!? because its really annoying when only one earphone works;P
I also saw these USB soundcards and since I have a keyboard with full USB ports I was wonderingen if a usb soundcard like:
http://dx.com/p/external-5-1-channel-usb-2-0-optical-fiber-sound-card-audio-adapter-48213
or
http://dx.com/p/virtual-5-1-surround-usb-2-0-external-sound-card-22475
would work on the asus eee pad transformer. In the reviews they say it is a plug and play device and it works on LInux and as we all know Android is based on linux.
Well I hope you peeps can give me some advice!!
Yours,
Kasper

Have you tried either of the following?
Compressed air in 2 short bursts into the outlet?
Using a DRY swab (not a cotton bud) gently insert into the outlet, but DO NOT TWIST.
(NOTE) :
You did not state if you are using stock ROM or custom ROM, so I will assume Stock. Back up your system using TWRP recovery, wipe all cache and then factory reinstall from start. After rebooting try to listen to some music or such and see what that does. If it works then try recovering the system back to what you had backed up and try again to see if the issue is still present.
(NOTE 2) :
To install TWRP recovery if you have not already, download goomanger from the play store and install the recovery from the settings (3 vertical dots). TWRP plays a bit better with the TF101 then CWM does.

Thanks for fast respondong. Ye I tried to clean it with a dry swap but didn't work. I am on Custom ROM CYANOGENMOD 10 by rayman. But I had this problem when I was at stock rom, revolver rom, liquid smooth, revolution HD and now cyanogenmod 10 by rayman. So this didn't make a difference. I think it might be something with the hardware since a friend of mine stood on my tablet for a few seconds with his full weight xD. But since the build quality of asus is pretty nice my tablet still works xd.
I will try to get TWRP.

Just installed TWRP recovery didn't work:S Someone other ideas or someone who have experience with a USB soundcard?

That was information that was really needed. Now it is sounding more like a broken input. Your more then likely going to need to do a tear down and see if the jack can be repaired easily. If not take it to a repair shop and they can usually fix it for under $30.00

[Q] Z710E Not booting after shutdown

Hey Guys,
I'd like to request some help regarding to my cellphone.
The cellphone is A 2 year old Htc sensation.
Did always do his job fine, never any problems, always had a spare battery so I could change battery's when the first one was dead.
The phone is Rooted, custom rom with ViperS 5.1.0. S-off.
So I was playing a game, and, a well known problem is that the sensation shuts down at whatever 5% sometimes, so that happened, the phone shut down.
I then put it on the charger, the light went on for a couple of seconds, and went out.
Since then I didn't see any sign of life on my sensation again.
I tried booting it with the spare battery, fully charged in a external charger.
I tried letting it charge overnight, maybe it would work again.
I tried putting it in to the bootloader.
I tried connecting to the pc, but that one doesn't recognize anything aswell.
Since it's +2 years old, I don't have any warranty anymore.
Does anybody know a solution or something? Or did anyone else experience this as well?
Or is the phone completely dead?
I'd like to hear from you guys!
- Cheers

I removed the battery, connected USB, reinserted it, jammed the wire in there a couple of times until it came back to life. Took quite a few tries but that may be my shoddy wire rather then the method. No need for the juopunotbeer software to run.

But did your PC recognize the phone when you connected it?

That means it's probably in QHUSB mode. You can retry the wire trick a couple more times to see if it comes out, if it doesn't, there's a unbricking tool in the development forum here somewhere to get it out of there.

It makes that windows sound when you connect a USB drive or something else, but it doesn't show up in the Device Manager from windows.
Will the brick thing still work, even if it doesn't show up in windows device manager?
I saw some movies on youtube where you saw: QHUSB_DOWNLOAD unknown device or something, but that doesn't show for me...

Allright, we Continue.
I have it in QHSUSB_DLOAD now @ windows, after trying the wire trick a couple of times.
