That makes sense however one would think USB 2.0 support would be a
good feature to have. There's quite a bit of people looking to utilize
pci passthrough and I'd imagine USB passthrough would be similarly
useful

Whocould shed more light on why?Well if it talks to the device in '1.1 mode' then the limit will still apply.At a guess, maybe the 1.1 hardware interface is a bit simpler? I suspect that they already implemented USB 1.1 to support the mouse and tablet interface, and passthrough was not much harder, but 2.0/3.0 implementation would have been a lot more work.James _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
