[Q] Can anyone help with getting my tablet to recongize a pc connection?

Current info on it - Android 4.1.1 and stock build - epad-10.4.4.23-20121127

I was rooted for about 2 months and had the tracking cilents frozen in titanium. About 2 weeks ago I saw a thread about the update for .23 firmware. I went and unfroze the clients and did a reboot with no problem getting the OTA update and restoring root. Before this I was able to hook up my tablet to a pc and transfer files. I didn't have need to use this function until last night when I discovered that it will no longer recognize being attached to the pc.

Essentially nothing happens. There is no sound and notification icon on the pc that a device was attached. Nothing shows up in device manager. The tablet doesn't show the USB connection icon. To make sure the usb port was good i connected my cell phone to it, bluetooth dongle, and a thumb drive. It works fine. This system runs XP with the drivers previously installed and working. I tried my laptop that runs Vista and worked fine previously when connected. Again I get the same issue. Even their Asus sync software on the pc shows no device attached. Just now I tried hooked up the tablet to my work pc and no change. That makes 3 pc's that I've attempted.

I can only think it was the firmware update. That was the only change I made to the system. Last night I did a factory reset of stock to see if a setting got messed up somewhere but there is still no connection. I probably lost root in that process and since it won't connect to the a pc, I doubt I can get that back. That is the least of my concerns though. I fear that something physical with the connector went bad that tells the OS a pc connection is occurring. Would that even be possible to happen yet work fine for charging the tablet?

Thanks for any suggestions or comments.

I mailed the tablet in for RMA and they, well someone at the center, signed for it on Friday. I tried doing the wipes and even downloaded the firmware from Asus and reinstalled it from the sd card. Nothing happens when it's connected. I got it working originally under XP following a guide somewhere on here. You have to update windows media player or something like that to end the failed driver update error. It will install the MTP support or proper drivers that are not included in XP. But yeah, now in Vista or my XP machines nothing happens and I can only assume it's hardware with the connector not recognizing a pc signal. It was working fine with JB installed before.

When I called into support their answer was RMA anyway. I had already done everything the support person was going to ask; reboot, factory reset, try different pc, make sure the usb ports work. Aside form a little screen bleed the tablet has worked without a problem until this last firmware update. There other ways for getting media to the device and that didn't concern me. It is the inability to connect the device to the pc for actions such as rooting, unlocking, or other similar functions that bother me. I had it rooted (lost now that I kept trying different wipes etc) but feared something going wrong later if I unlocked it and lost warranty. Once warrant is up this device is fair game and going unlocked for sure.

In case anyone else encounters the same problem, apparently the connector went bad on the tablet. They replaced the part under warranty. Took about 10 days in total and so far the only issues I see with the tablet is bent metal where the connector and one of the prong holes for the dock is and the screen. I assume the bent metal is from the tools used to pry open the case. The glass over the screen seems mushy and a bit popped up now on the edges. Don't know if that is something I should worry about or just expect since it was opened.

It did come back with 10.4.4.16 firmware. I was real tempted before to unlock and really let the tablet shine but hesitant now. They may not have covered the warranty repair if I did and I don't have another $500 to drop if something else goes bad that isn't minor.
