First, let me say that I've searched and searched and looked for all the info I can find about people having similar problems. I've yet to find anything that works for me, and I'm at my wit's end on this...
A few days ago I tried [unsuccessfully] to update CWM on a GTab. I can't get into recovery at all now (it just hangs), but this problem predates that.
The problem I have is that I cannot get any PC to recognize the GTab - in any mode - and I've tried 4 computers with various operating systems. I've tried Fedora, Ubuntu, Windows XP and Windows 7 and none of them will see the GTab at all. They won't see it with debugging on, with it off, in APX mode or anything.
I have gone through half a dozen cables and tried every USB port I've got. It just simply will not recognize the tablet in any way.
I'm toying with the possibility that the port might be damaged, but I can't think of a good reason why that would be the case. The tablet has been well taken care of, and all the other ports work just fine (audio, USB storage, SD).
So, has anybody else run into this issue and found a fix for it?

Read: Only ClockWork recovery on boot
Check dmesg to see if tablet is detected: A self inflicted wound
Also: [Q] (really) bricked g-tab.
If you can't boot the tablet at all--into either ROM or recovery--, then there's nothing you can do if your USB isn't working. If you can boot into one of them, then there's hope.
I managed to get CWM installed (was my bad on trying to flash the wrong one to upgrade it anyway). It's always booted just fine into the ROM, and everything works but the USB connection to PC.
I am actually a Linux admin by trade, so I kept an eye on all pertinent system logs and outputs when I tried it on the Linux box. No dice.

Well, you have to be careful about these things. APX mode, for instance, only "connects" to the host PC once, so if you unplug and replug hoping to see USB device recognition messages from the Linux kernel, then you will be disappointed.
What about on the gTablet? Does the kernel print anything pertinent when the cable is connected to the host PC (enable USB debugging first)? Are there any other error messages or diagnostics?
That's the troubling part. I'm finding absolutely nothing. Nothing at all to indicate there's any kind of issue. My guess at this point is that the USB port must be physically broken. I can't see any other way to make sense of it.
Here's one final suggestion: Open the gtab up and disconnect the battery. Wait 1 minute then reconnect the cable.
See if it helps. (It's for people who can't even boot the tablet into APX mode, but, try it before concluding that it is a HW problem).
Happy Holidays Everyone!!!
Phone:
Tmobile T959 aka Samsung Vibrant
It is on stock Froyo 2.2
It has the 3E recovery.
I tried on 2 computers but I can NOT connect via USB it gives me USB malfunction error. The phone does charge. I can put it into download mode vie the 3 finger trick. When you connect it does give you the option to click the green Android icon Connect to USB. So it is talking to the computer, the usb is not totally dead.
Problem:
I need to root this phone. I can not use 1 click or anything else because I think there is a problem with the USB port. I can get files onto the phone via wifi or using the external sd card.
I tried using the update.zip file BUT because I am on the 3E recovery it will say signature failed. I can not run the install.bat to get it back to 2E recovery. I can not use ODIN because the Windows will not detect the phone properly.
What workaround can I use to root this phone? How would I use terminal on the phone?
HOW WOULD YOU ROOT THE PHONE IF YOUR USB PORT WAS "broken"?
THANKS for helping!
As far as I'm aware, you can't root your phone without the USB port working as most (if not all) root methods send their commands and files through ADB. Your pretty much stuck, unless your phone is under warranty. In that case, just go to your carrier and see if they'll give you a replacement device.

It's out of warranty
I think there may be a way to do it via terminal emulator on the phone.
If this is possible, can someone please post how to do it.
anyone with a work around?
damn!
Am I stuck or does anyone have a way for me to root this phone without the using the USB connection (USB does charge, It will know when you connect to the pc for USB storage BUT windows will say not recognized. I tried it on 4 other pc's same results. I think something is wrong with the OS of the phone. I think the previous owner tried to update with Kies and it messed up the phone. The phone does boot and works.

I did all of that.
I think something is wrong with the phone's OS that is effecting the usb port.
How do I root this phone WITHOUT the USB port?
There has to be a way!
Can you determinate VID&PID of phone?
I can get into the device with airdroid and see the system files.
Which files do I need (or which apps) and where do I copy them manually to get it rooted?

Is there not a device forum where you might could get some better information? My thinking is, a lot of the people (or most of the people) who may know some workarounds can probably help, but they don't check this section very often or at all.
Even if there's not a section for that model, I'm thinking there's probably one quite similar. Also a lot of times, a big portion of the userbase of one phone, will migrate to the same model when they upgrade.
Just throwing out some ideas in case that's helpful. My only advice on the problem itself is that I would look further into the driver issue. I've helped several people with very similar issues that we finally were able to correct.
Have you tried to ADB the device just to pull the serial? With USB debugging enabled. Have you installed the SDK and tried the naked drivers? There's some things to pursue possibly so you can have more information for the person who helps you get things straightened out.
I have the International (i9300) S3 and am running Temasek's ROM (v99.4), but I cannot connect it to my PC via USB. I am currently using AirDroid for all my Phone to PC transfers, but ADB is also not working and this will cause a problem in the future if I manage to brick my device. The only way to use ADB on my device currently is to boot into recovery (PhilZ Touch 5). This problem has been occurring for that last few months, but as I believe it is an isolated incident I didn't post about it. I decided to start this thread to see if anyone was having the same problem and to see if anyone found a work-around or fix for it.
Thanks in advance,
MiracleM4n
EDIT: Turns out it was my cord. For some reason the stock Samsung Micro-USB cable was not working correctly.
have you enabled debugging in developer options, or tried reinstalling all drivers
Thanks for the quick reply. Yes I have reinstalled all drivers and I do have it enabled in Developers Options. It does not show up in Device Manager as "Other devices" so this leads me to believe that it might be an issue with the device itself.
I have tried reinstalling using drivers from Faryaab's thread and it is still not working. I believe this might be an issue I am going to have to live with.
So I went on trying the leaked Samsung firmware for my GT-I9300, everything seems fine, may be even better than the last one released here in Mexico, thing is, now that I'm trying to pull some files from my device via ADB it says that it is unauthorized, I searched for a while and I found that there needs to pop a prompt to authorize my PC to connect via ADB, but there's no such prompt. I tried checking/unchecking the USB debug mode on my device, restarting it, re-plugging it, different ports, ADB over the network, restarting my PC, anything that I can think of, and no luck.
Can anyone give me some insight on what can I do?
Thanks in advance and I apologize beforehand for my weird English.
Are you doing it through recovery? Are you rooted? Little more detail would help to get a better answer.
Rooted ?

ME7 is a leak (production build), "adbd cannot run as root in production builds" will always pop up.
i dont know how to fix this, but im pretty sure its a line in the build.prop and something in /system/bin.

No, didn't tried it via recovery, I might try, but it may become a hassle, since I do this frequently. Also, I tried this before and after rooting it with no effect whatsoever.

hmm, theres only one thing that solved this problem, you have to flash a different kernel!
So... now that I think with hindsight, I did something pretty stupid, and I'm going to need some help, since I have no idea what to do.
I have a Nexus 9 tablet, and I never liked it. The OS is just so slow and laggy, and it overheats, and it has many other problems. Quite a couple of times, I installed custom ROM's and so on, and I never had a problem. Let me explain what I did now.
Around a month ago, while looking on the internet, I heard this thing that if I install the original software, but with no encryption, it would work better. It sounded cool at the time, so I downloaded the Nexus Root Toolkit, and did it.
Everything went well. But then I heard about a custom ROM that was apparently working even better, Dirty Unicorns, so using the same toolkit, I installed it. For the first time, my Nexus 9 actually worked the way it is supposed to work, but the custom ROM still had its problems, it crashed from time to time. I was thinking about possibly returning or selling the tablet, so that's why using the Toolkit, I reinstalled the original software. But, if I went all the steps, and also locked the OEM, my device then showed a flag saying that it was a development device, while booting up. So, after messing around with the settings of the Toolkit a little, I decided to reinstall the software, but leave the bootloader unlocked.
But after some time, I reinstalled my Windows, and I also reinstalled the Toolkit. But that's when I started to have problems. My tablet wouldn't connect to my laptop anymore. I used the toolkit and uninstalled drivers, reinstalling others quite a couple of times, and that's where I think that I messed something up. I managed to eventually connect my tablet, and I rooted it, after rooting it, I connected it again. But adb wasn't working for some reason. A little annoyed, I simply copy pasted the zip file of CM13 into my tablet's internal storage, and I rebooted it to the recovery, TWRP. But the recovery failed to flash it, saying something about an Error 7.
Now that I think about it, I was stupid, since after that, I performed a complete factory reset, resetting my TWRP backup too. I tried to connect it again, nothing. It didn't connect at all. I plug it in, my computer doesn't even recognize that something is plugged in. No Nexus 9, no Android Device, no anything. I booted it in fastboot mode, and it worked, my computer recognized it, and after I downloaded a ROM zip file again, I tried to connect the tablet back and flash it manually, but nothing. It didn't recognize anything anymore.
I tried to reinstall the drivers countless times. I deleted what I had, reinstalled it, nothing. I uninstalled and reinstalled the Toolkit. But strangely, now, even if I know that I installed the Google USB drivers, and the ADB drivers, as I even installed Android SDK, if I use USB Deview, it doesn't show me any of them. I can't see any Google or ADB drivers, although I tried installing them multiple times. So now, I'm stuck with a tablet with TWRP and no OS, which I can't connect to my PC, and I can't use ADB or fastboot.
Is it something from my laptop? I can't check to see if it will connect to another PC right now, so I don't know for sure. Is there any way to delete all the traces from my (failed) attempts at reinstalling the drivers, and to install them again properly? Or is it something from the tablet itself? I don't have an OS, so I can't enable USB debugging.
So, shortly, I have no idea what's happening. And I'm quite obviously a noob in all of these. Can anyone help me? Please?
If you boot into the bootloader and from a command prompt type fastboot devices you don't get anything?
Sent from my Nexus 9 using XDA-Developers mobile app
I still couldn't get ADB to work, but I managed to work out fastboot. It may be something from my USB cable, it works perfectly.
I flashed the original software back, and I'll go to check my cable, although I feel kinda stupid that I didn't think about that in the first place.
Thanks for the help anyway.
If fastboot is working and bootloader is unlocked, you can still install a factory image.
Depending of your device download for wifi Version:
https://dl.google.com/dl/android/aosp/volantis-mob30p-factory-2cb57a1b.tgz
If you habe the LTE variant:
https://dl.google.com/dl/android/aosp/volantisg-mob30p-factory-ae9ce05a.tgz
Extract the files and put them into the same directory link fastboot and execute the flash-all.bat
WARNING: Any data will be erased!!! Also TWRP
Now it should boot up with stock firmware.
If you want your device decrypted install twrp. format the internal storage and flash the pure nexus rom which i can highly recommend and is decrypted by default. Dont forget do flash gapps
my issue is same
what if someone USB- debug is not enabled , is there any possibility to do that , i have a device nexus 9 , rooted it it went into bootloop then i factory reset it , and now my adb is not communicating , if there is any options?

Use fastboot, not adb.
what if fastboot isn't working, either?

Yup. I can boot into the bootloader, and from there (or from TWRP) into fastboot, but no computer I've connected it to (and I've tried many) will recognize it. Doesn't show up in Device Manger or lsusb, doesn't show up from either "adb devices" or "fastboot list devices" (the latter just hangs there saying "Waiting for any device"). The USB on the tablet itself is fine, and I even replaced the USB daughter-board just to be safe.

Hi, uberSkeptic...
Just a quick thought... Have you tried a different USB cable?
Rgrds,
Ged.
Edit & Additional...
The command is not fastboot list devices... it's fastboot devices
One last point... Ensure your Nexus 9 is definitely booted into fastboot mode and not just HBOOT (the bootloader). Take a look at the two screenshots below - your Nexus 9 should look like the screenshot on the right, the one with my green explanatory text.
Apologies for the poor image quality; there's no way of taking a screenshot in the bootloader, so I had to take photographs instead.
Hope this helps and good luck.
Thanks for the advice and going so far as to photograph the hboot/fastboot screens, but unfortunately I have indeed tried multiple USB cables, including the OEM's and I've definitely successfully gotten the tablet into fastboot but it doesn't show on the computer with either fastboot command (devices or devices list).

I'm out of ideas then.
One of my first thoughts was possible Windows driver problems, but as you mentioned you'd tried it on several different computers, that didn't seem to be a likely cause of the problem - I mean, you'd expect at least one of 'em to work! Maybe somebody else can help with a solution.

Sadly, me too. I even tried using a flash drive with a micro-USB connector on it, which I used to use to do nandroid backups, but now TWRP doesn't even "notice" that the USB drive is there (or any USB drive connected via an OTG cable).
Too bad, too - the tablet is otherwise in great condition and even has a custom-painted backplate (long story).
Thanks for trying to help, though!

Mmm... (scratches head, raises eyebrow quizzically)...
If I was Hercule Poirot and this was a murder case, and with all the suspects gathered in one room, prior to revealing a brilliant deduction... I'd be casting very dark glances in the direction of your Nexus 9's USB port right now as the likely culprit here.
Think about it. Different computers. Different USB cables. An OTG cable... And none of them work. What's the one thing they all have in common?
Answer: The USB port on the Nexus 9 itself, and where you've replaced the USB daughter-board.
Maybe, possibly, that replacement don't go so well. Maybe there's some unknown problem with it. I can't comment too much on this, 'cos it outside the scope of my knowledge - I'm a software guy; circuit boards and dismantling devices to fix 'em isn't something I'm comfortable with. I always think I'm going to damage something or rip a wire out somewhere, so I bow to your superior knowledge in this area, as I may be talking complete cobblers here. It certainly wouldn't be the first time.
Anyway... Sorry I wasn't able to help find a working solution for you. If anything occurs to me that might help, I'll be sure to let you know.
Rgrds,
Ged.
I would be suspect if the replacement as well if it weren't for the fact that I did it only AFTER the other symptoms/problems appeared. Hence the replacement (which is known good because the battery charges no problem). There cables and everything inside the tablet tests just fine... It feels like the firmware for USB is somehow corrupt or something.
Thanks for all the advice, though. ?
So I can't believe I didn't think of this before, but when I run "dmesg" from the terminal app included w/ TWRP, I see that there a TON of errors, mostly referencing problems accessing the recovery image. I could screenshot it, if anyone at all might be able to tell me a little more specifically what the dmesg log is trying to tell me...
