I think I've exhausted my options, hopefully somebody here has an idea.
From day 1, my TF300T has been unable to connect to a PC. At first I thought it was because one of my cats chewed on the USB cable before I could try (it still charged, just no PC connection) so I didn't do anything while it was still under warranty.
Since then, I've tried 3 different cables, multiple PCs and a Macbook, and I can't get anything out of it. It's not detected at all by the computer - no unknown device, no prompt for drivers, no device connected sound when I plug it in. No reaction on the tablet either, whether USB debugging is on or not. I also tried replacing the USB port on the tablet, but got the same thing. I doubt it's a driver issue since I'm not getting anything at all on either end of the connection.
It DOES connect to the dock ok, and all the dock functions seem to work. I've tried connecting the USB cable to both the tablet directly and the dock, and I get nothing from either port.
I'd really like to be able to flash custom ROMs on it, and I can't find a working way to root or flash it without a functioning USB connection. Could it be the third-party USB cables giving me problems, and if so, is there one that actually works? And if not, is this just a lost cause?

Hi there...
A quick question about the USB...
Is is at all possible to have a USB-port that can still charge the phone, but at the same time is "dead" when you try to connect the phone to the computer ??
I have also asked about it here:
http://forum.xda-developers.com/showthread.php?t=1179171
The story is that the Phone (SonyEricsson X10i) can be charged fine, but when i connect it to the computer, my computer say that the hardware is not recognized, nomatter if it is in flash-mode, mounted from recovery or in the normal way.
And the phone don´t even show anything about USB connection in the status bar eigther.
I have tried 5 different computers now, and 2 different usb cables.
I have also a X10 mini and a Desire HD that works fine on all the computers and both cables.
I have tried to remove software, remove drivers, clean computers, reboot, check the memory-card in the phone, install software and drivers and all other things i can think off...
It is two windows 7 and three windows XP computers btw.
So is it at all possible that the phone can still be charged, but data-connection fail ?
As i see it, there must be some kind of data-exchange or else the computers would not even say "hardware not recognized"...?!?
I'm not quite sure I understood your question correctly, but let's see if this helps:
I used to have phone that didn't have drivers for Windows I used at the time (I think it was Windows 7). That meant that Windows wouldn't recognize it (when plugged via USB cable) and will not therefore provide power to that USB port (hence the phone will not charge).
I was able to get around the problem by going to the device manager, locating the relevant "unknown device" and force installing some random drivers for it -- I don't even remember what it was that I picked -- something that Windows would allow me to do. Of course the port wouldn't work as a data connection like this, but since Windows now 'knew' the device, it powered the USB port and I was able to charge my phone from it.
My problem is that I actually can charge the phone ok...
But I am not able to make a data connection between the computer and the phone at all...
My question is then, if the usb connector in my phone can somehow be broken even though I am still able to charge the phone...?

I'm fairly sure that yes, the contacts or the controller can be broken so that you can still charge but be unable to establish data connection.
i'm trying to connect my shield to my computer to do some basic android development (i have an app, it works on other devices, want to test it on the shield).
my problem is, when i plug it into the computer, nothing happens. to clarify, i don't mean that the drivers don't install correctly and then i can't do anything. what is happening is actually nothing. the computer (windows 8) does not recognize anything is happening, the device manager does not see any new devices even after scanning for hardware changes.
the shield is in development mode, and has usb debugging turned on, but i don't get any response anywhere. the shield does at least appear to charge over the usb cable, but that's it. listing adb devices also provides no output.
do you guys have any idea what might be going on that the device isn't recognized on any level that i can tell?
It sounds like either the USB port or the cable you're using is faulty.
Have you tried switching USB ports, to see if it's recognized then? And have you tried using a different cable?

If youre just trying to connect thru adb you need the universal naked driver. If the shield isnt being mounted try a different usb port and make sure youre using the shield cable as well. My samsung cable will charge it but i cant transfer data with it.
Did this get solved?
Did this ever get solved? I have the same issue. I have tried everything everywhere has said to do with no luck.
I'm wondering if my USB port on my older One S is dead. I have two, one old and one new. When I plug the old one in my computer charges it but doesn't recognize it. On the other hand, the new one is recognized and also charges. I'd like to get some stuff off the old one, but the connection for the digitizer is gone, OTG to USB didn't work, and USB debugging is disabled.
So when I go into Device Manager I see it under Portable Devices and in Properties, and it says it's working properly. The thing is under Other devices Universal Serial Bus (USB) Controller has an exclamation point by it. I try and resolve the issue, which only appears when I plug the phone in, and it says Device Driver Software was not found. I also can't get into the device from Windows Explorer.
That's kind of ridiculous, seeing as everything else I use that's USB works fine besides my old phone and the new one works great (Besides the SIM Network issue I'm having with that).
What in the world is the issue here exactly?
I've had my OPO for a little over 7 months now. My issue began when I had my desktop at a friend's house and plugged my phone into a USB 3.0 port to grab some videos off the phone when the phone suddenly shut off and would not turn back on. I thought it was bricked somehow but after leaving it plugged into a USB 2.0 port for some time, the charging screen came on and I was able to turn the phone on, but since then both OTG and MTP/PTP transfer doesn't work. If/when the phone is plugged into a computer, it gives an error and Device Manager shows
"Port_#0001.Hub_#0004 Unknown USB Device (Port Reset Failed)" and I'm not only able to charge the phone with one out the dozens of micro usb cables I have. I've tried several cables and a handful of different computers and OSs (Windows 7,8,8.1,10, Ubuntu 15.04, Kali Linux) all to the same result.
I'm running COS 12.1-YOG4PAS3JL, rooted, and have TWRP installed. The phone doesn't show up when in Fastboot mode or the bootloader either. Nothing changes when I disable or enable USB Debugging as well. With DriveDroid if I set the USB system to "Standard Android" the phone reboots and that seems like the closest I've been able to get to any kind of progress. I've gone through unbricking threads as well as Googled until my fingers bled but I'm yet to find anyone with a similar situation where the phone isn't bricked, the micro usb port isn't broken, I can't pick between MTP or PTP mode (USB Connection just says USB is now disconnected), and I'm not running a custom ROM. I tried replacing the micro usb on the phone so I now know that it wasn't that that's been messed up but I'm not sure where to go from here. Any suggestions or help is greatly appreciated.
As the title states, my phone is no longer being recognized by my computer when I plug it in. I've tried multiple cables, multiple ports on the computer, both ports on the phone, factory resetting the phone, uninstalling and re-installing drivers on my computer, booting to Ubuntu so I wouldn't need to worry about drivers. Nothing has worked. I'm not even getting the USB prompt on my phone when I plug it in. It DOES charge but I'm not able to transfer files, adb or anything. ASUS wants me to send the phone in but I don't want to go who knows how long without my phone, plus I don't think it's right that I have to pay to ship it when it's their phone that is ****ting the bed. Could anyone PLEASE help me? Thanks.

If your phone won't connect to the computer using the USB cable, then the FIRST thing most people do you've done, which is switch cables and rebooting the phone (factory reset is extreme but you did that also).
The second thing most people do is install the manufacturer's drivers, which you also did.
The third thing you can do though, is connect the phone to the computer WITHOUT the USB cable (i.e., over Wi-Fi) because that will work even if your phone port is broken and even if the USB cables are bad and even if the drivers aren't on the computer.
Below are screenshots of just some of the ways to connect the phone to the computer over Wi-Fi without any cables, and if you want, you can follow one of my tutorials on the subject.
Hope this helps.

Would I still be able to adb using the wifi method? My main issue is trying to remove the old Google Pay app. Which I'm unable to unless it's through adb.
Just an update. I was, in fact, able to run adb commands while connected using wi-fi. Thank you @GalaxyA325G for your input.

Not sure what to tell you about your signal dropping, but
is the video I used to finally use adb via WiFi.
Have you tried clearing the adb authorizations (in developer options) with the phone disconnected and then connecting? Sometimes a change can trigger the phone to stop recognizing the computer as allowed without treating it as a new connection.

Sounds like you're stuck with WiFi or the repair then.
