When we first plugged it in, the standard MS driver got installed, the message is
#I121 Device install of "USB\VID_0930&PID_A000\0010101640000514W" finished successfully.
the USB icon appears in the system tray, the mouse works but nothing else does. Not Explorer, not task manager, not the Start menu. NOTHING.
The only way to regain control is to unplug the computer.
We tried three times with the same tragic result.
This was my guest's drive. I have an identical drive, same class ID, same driver, and no problems ever.
She's using her drive on a Mac computer and it holds data just fine, but does require a powered hub, which I also tried here.
