Comment (by ithamar):

Yes, could you attach the output of "listusb -v", giving us a little more
detail on the actual usb devices attached?

I suspect we still have a race somewhere, there's an awful lot of errors
(due to retries) coming out of the usb_hid driver when you switch, and
that also delays the removal notification. At the very least, I think we
could simply give up on the device when trying to unstall it fails (See
the "usb_hid: Unable to unstall device: Device stalled" messages in the
syslog).
