I don't understand how to just "report" the device as "high speed". Doesn't the device specify which speed? Moreover, it seems the device doesn't compromise on speed - when I inserted it into a USB 2.0 port, it doesn't work. > Also, there is code within Intel for the USB-over-IP standard > implementation that should work for this type of device.

So far, my dig hasn't found anything, but I'll keep looking for/asking...
