Hi Mattia,

I have the same issue since KVM 73.

It seems to be related to USB 2.0 hardware. Set your USB Hardware or your 
host in BIOS to 1.0 or 1.1, boot again.
This will result into a max. transfer rate of ~32-64 KB/sec but your 
Hardware will work more stable.
But some USB 2.0 components will still fail if they are not fully USB 1.x 
capable.
I have an old USB HP printer that works slow but fine and a new Canon that 
crashes Windows with exactly the same driver that hooks up (usbuhci.sys).

Sometimes it just doesn't do anything and when unplugging the printer or 
shutting down the bluescreen comes up.

Also have a look on the dmesg of your host! I recognized there a massive 
connect/disconnect occurence of the given USB device when it is physically 
connected.

The reason seems to be somewhere in the KVM usb layer I tried to find it 
out but no success.

Best regards,

Erik
