This patch enables USB UHCI global suspend/resume feature. The OS will
stop the HC once all ports are suspended. If there is activity on the

To enable autosuspend for the USB tablet on Linux guests:
echo auto> /sys/devices/pci0000:00/0000:00:01.2/usb1/1-1/power/level
Hmm, did you ever got this working sanely?
/me sees bus disconnects in the guest ...
port->ctrl&= ~(val& 0x000a);
+ port->ctrl&= ~(port->ctrl& 0x0040); /* clear port resume detected
*/
}
This chunk looks suspicious ...
I suspect the port suspend/resume emulation isn't complete.
/me goes debugging,
