Computer Troubleshooting

[thomasdunaj]

I have installed all of the latest BIOS watches cheap and all drivers, including USB 3.0 updates.  I have turned off power management for USB in Device Manager and I have disabled USB selective suspend in the Power Plan.  However, the USB 3.0 port continues to randomly turn off.  The only way to restore it's functionality is to reboot.  I have continued to have this problem since I bought the computer in April.  I have a Logitech mouse nano receiver (latest drivers installed) plugged into the port most of the time, but once it stops working, no matter what I plug into the port (HD, USB modem, Thumb Drive) it does not work.  There is no issue with the 2 USB 2.0 ports.  I like to use this port for my mouse receiver because it is out of the way being that's it on the back of the right side.  Anyone else having this problem.  Sure seems like a driver/software problem, but I'm starting to wonder if it's a hardware problem since I don't see other posts about it.

While I have had a few BSOD's and this USB 3.0 problem, I absolutely love this computer.  The form factor and battery life is the best!  Running Windows 7 Home Premium 64 bit SP1.

I have solved this problem using the latest firmware and drivers for the Renesas USB 3.0 Host controller. To see all the details, visit the other thread in Toshiba forums:

Maybe you got bit by this bug.

   Binary files in some USB drivers are not updated after you install Windows 7 SP1 or Windows Server 2...
