This should definitely not happen. And it now I wonder how functional your
controller is at that point.
all worked fine until 'Jun 16 00:36:55'. Usb device was used over libusb periodicaly (1-5 minutes) all that time.

Still after all this time, this is probably genuine.
I think this was normal usb device plug/unplug.

And this. Looks like a bad cable.
I think this is of usb device failure, but the bigest problem is that blocked hang. There isn't any cable except wiretraces on motherboard :D.
That device is like: http://www.aradasystems.com/Upload/ProductImages/128835373116845000image_usb_dongle.jpg and connected dirrectly to
the usb port, which is inside server case.
