[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.

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.

USB Storage can't be turned on

So I got an incident with my phone, if you wanna now about it, its at my sig, but the thing is that I dunno why or how, sometimes my computer does recognizes my phone and display the Turn on USB storage option at the notification bar, but each time I try to turn it on it just wont work. Attached is a logcat whenI try to enable it, maybe someone could tell me why it wont work.

What rom are you running for those off that are on the xda application?

Normally I got two nandroids a GB based one and an ICS based one, right now Im using both Eagle's Blood 2.3.7 v2.8 and ICS 4.0.3 Build 1. But I had this problem since... always. I'm a flashaholic so i have tested actually every rom from stock 2.2.2 to beta 4.0.3... I even have a nandroid of my original ROM (the one that came with it when y bought it and rooted it) and not even there works. The only clue i have right now is that only if I disable USB debugging it will randomly connect.

This may sound dumb but have you tried a different usb cable? I had the same problem and tried my girls and my phone was able to connect each and every time. another thing I noticed with my phone is that it sometimes won't connect using windows 7...xp no problem but 7 it plays hard to get.

Holy Mother of God! I did it!

Then all I had to do was NVFlash again, restore the stock 2.2.2 Nandroid i had somewhere and play a bit with the USB mount/debbug options, flashed both storages (using gparted for the microSD) and it works! Now have to restore everything to my SD and reflash latest cm7...

Did you ever figure this out? Sounds like your having the same problem that i am.
I've tried at least 6 different cables, home PC, work PC, laptop and a co-worker's PC that didn't have anything vmware installed (had a hunch that vmware usb drivers were the cause). Oh, all the computers were win7x64.
I've only rooted my phone and upgraded to 2.3.3 so nothing crazy going on there and it's worked for months since i did both of those.
I have a feeling that this may have been a recent windows update, but no clue when or which one because i haven't really cared that it didn't work. If i had to guess i'd say mine stopped working about 3 months ago... again, hard to remember.

Make sure usb debugging is turned off.
Plug in the phone, enable usb storage.
Right click on the phone drives in the explorer and click on eject.
Turn off usb storage.
Unplug and plug in again.
Enable usb storage.
Drives should work now.
This did it for me. Since then if I remember to eject before unplug I haven't seen any issues.

Thanks for the reply, I'll give that a shot.
Curious though, when yours was having problems, did windows detect anything? For instance, when I plugged mine into my co-workers pc there are zero pop ups about new hardware detected.

I had the same problem. Dirt in the mini-USB port can cause that problem.
Take a can of compressed air and blow it into the mini-USB port (blowing with your mouth isn't enough). Also, take a close look at the port with a magnifying glass and look for any dirt or discoloration in there.
Do the same with your cable.

Hi, this problem occur to me after I've installed RemICS 1.3.2 ROM (CM9 based), I did follow the installation steps from beginning, when the problem occur, I did re-flash the same ROM several times, but this problem still unsolved.
I did try all recommendations (blow out dirt, disable usb debugging etc) but still not success.
This ROM should able to detect USB when phone connected with PC, but somehow I don't know why. Any experts recommendation?

Ok, I just found the problem. I can hear now the tone of PC detected USB when plugged-in, and I update the driver. then Voila!!
Thanks All..

Hey, just thought I'd register an account because I stumbled upon this thread because I had the same issue verbatim and I managed to get it working.
I ended up using the USB 3.0 ports on my desktop and suddenly it picks up my g2x without fail everytime. With that said, I'm lead to believe that perhaps its an issue of power. Maybe the USB 2.0 ports you're using simply aren't providing enough power. Not sure what its worth or if my issue was something unrelated but maybe that bit of information is something to work with. =)

Found another solution that fixed the problem for me.
If you are using Windows XP, log on as an Administrator and open Device Manager
Select View > Show Hidden Devices
Scroll down to Storage Volumes, and expand
Right-click on each entry and select Update Driver.
This fixed the problem for me!

USB not working
When I try to connect to the computer to transfer music or whatever to the Infuse it won't let me. I plug in the data cable click mass storage, click connect USB I get "do you want to scan and fix". If I click scan and fix I get "check disk options". Any combination of the check boxes will make the phone disappear and starts the scanning process, like I had disconnected it. I'm running Zeus 6 w/ICS theme for build 6. Is there any special way these disks should be formatted? Any help would be appreciated.

Wow! Nothing?
Now when I plug in to the computer it doesn't even recognize the phone. It's like I never plugged it in. The phone will still asks kies/media/mass storage. I click mass storage then click connect to PC then nothing. It's almost to the point of going out on the deck and teach this phone how to fly.

my infuse is doing about the same thing.
plug it into the wall...nothing.
try different outlet...nothing.
try different charger and cord...nothing.
plug it into my computer...starts to charge only, no usb mode.

Skyrocket usb error

Hi everyone, this is my first post requesting help.
My skyrocket charges with the usb port but wont connect. I tried a darkside wipe, format of system data cache emmc and reflashing many roms. I want to use odin and try to use stock.recovery and rom to see if it works. I enter download mode and it still wont connect. I reinstalled kies and still doesnt work. Its not my computer cause my t989 galaxy s2 connects and these two phones are nearly identical.
Running ics real thing 4.2 v9 cwm touch by realsk8tr

If possible, try another computer.

I have the same problem with mine. This is a new problem that just started a couple weeks ago. Mine seems to be a hardware problem since it won't recognize USB connection in CWM, Odin, the stock rom, or my current Sky ICS rom.
I'll flash back to stock and send it back for warranty repair once I get another phone to use. I have a contract renewal coming up in May, so I'll do something then (I bought this one off contract, so I have to send it to Samsung)
Its a real pain because I have to transfer everything wirelessly between to/from my laptop.

It is a new problem that occured after using the ics leak. I cant believe there isnt a solution. Can you link me to a zip method that will return me to stock GB without the use of odin? And can i send my skyrocket in for warranty replacement? I never got insurance on it, i brought it in november from att nyc. This skyrocket also gets dev/block errors upon format. Any ideas guys?

Just for the heck of it try uninstalling kies, the drivers should stick. Sometimes that'll do the trick

Mine happened while I was still stock/rooted. I had changed nothing for several weeks. It just stopped recognizing when it was connected to USB. I have tested on multiple computers and tested another sgs2 on my laptop. The problem is definitely with my phone. No other computers recognize my phone is connected, phone won't mount USB, etc. Yet other phones work fine when connecting to my laptop.
I even flashed back to stock GB 2.3.5 , etc. Its not an ICS issue since this happened prior to flashing ICS (it actually went tits up in March prior to the leak).
I have a GB 2.3.5 Nandroid backup I'll flash before sending it to Samsung.
Samsung warranty is good for one year. AT&T will only do a 30 day exchange type warranty. Anything after 30 days has to go back to Samsung repair.
My only concern is without a USB connection I can't flash to the stock recovery. I can flash to stock GB and unroot and clean it up on the ROM side, but it will still have CWM recovery. Oh well.
The way I see it this is definitely a hardware issue. Samsung should fix the hardware problem regardless of the recovery software.

I guess I should have stated I have tried about 6 different cords.... I am a Systems Admin, so I've tried all the obvious fixes. It just absolutely will not recognize a USB connection anymore. Also, none of the computers recognize that a USB device has been connected.
It's definitely something wrong with the USB on the device.

I did flash the note modem once maybe my efs is corrupt

No, it's not that. It's hardware. It's almost certainly a cold solder joint. Must be a bad batch of I727s out there, mine's doing the same thing.
Sunday, I had a 30 minute call. After, I noticed the phone would charge, but couldn't get the computer to see it as a USB device. Last night, after an hour long call, I tried it and it worked. Managed to get it into download mode, flashed the stock .tar with ODIN, and got back to stock. About five minutes after that it started failing again (charging but not connecting, etc).
I'm using my T989 as a charger. If you can find a way to charge the battery, what I'm testing now might work. [EDIT: I re-read the OP and you have a T989 as well so you're set!] I'll post back. I set up a call to a test number (909-390-1390 is a 1Khz continuous tone) and placed the phone on the back of my video card with the USB cable connected. If it connects, we'll know this works for heating the phone up enough to temporarily 'fix' the cold solder joint.

But my skyrocket charges perfectly, via wall charger and usb, i have no need to use a external charger

You may not have the same issue as I have. I will note that as mine degrades it'll start acting as though I'm repeatedly unplugging it (PC rapidly going through USB connect/disconnect cycles, etc), then it'll still show that it's charging although the PC no longer recognizes it, until finally it acts as though the USB does nothing at all. The hotter I get the phone, the longer each stage takes.

Im just concerned that cwm will bone you from Samsung. one crazy idea is force brick so it doesn't turn on at all if they can't see recovery then you can anyways claim power failure

This is a good thread. My skyrocket is a used one from Texas. Won it on Ebay. Shipped out quick. Nice unit except it did exactly what I see described here.
It worked great the first day as a stock ice cream sandwich or whatever you call the ATT skyrocket software package Android 4.0 something. The USB hookup started getting flaky the more I used it, it would disconnect. It was unhooking, and I'd click to "copy files to PC" button again and again. It made rooting it a real challenge.
As if getting your arms around "Odin" wasn't intimidating enough...
I thought it might be from being jiggled, so when I was stashing the last of my downloads to flash CM9, I was careful to have it on a surface when I gently touched the screen and got all the files copied I wanted, and the phone, computer, and data cord left untouched, appeared to "work" ahead of the epic fail.
After I flashed the new CM9 from (wow thanks team chopsticks!) the USB is not recognized either in the skyrocket nor the computer, nothing. It shows charge, that's it.
I intend to get a USB reader for the microchip as a work-around. The phone screams. This is my second skyrocket and the new CyanogenMod 9 is the love I've been looking for. At last, a phone that can bring up a gallery full. My first skyrocket had trouble when the 32 GB microchip approached full. This one flips the 20 GB worth of pages full of folders up like nothing flat.
Also, interesting detail on this used Ebay phone... the first thing I noticed is you can't power it off. The seller shipped it with the battery removed. I tried plugging it in, leaving it unplugged, this i727 just will not power down. I do love the touchwiz recovery, and how you can select to reboot and then choose to boot into recovery. That part worked nicely and I am over all happy.

I know its late replay but I got solution!
I had same prob all i did was took toothpick stick it inside phone USB connector thing and pushed it little bit up and now it works perfectly FINE!

Yes the toothpick fix does work. Had the same problem with mine. Read about using the toothpick to fix this problem from a post back in December of last year. Don't pry up too much and break the toothpick off inside. A little twist is all it needed on mine. Noticed some dirt and grime came off on the toothpick. Maybe this helped clean it as well

[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.
