This is interesting, because with my pci passthrough i only get USB1.1
speed which is about 1,5MB/s max (i actually get 0,9MB/s).. so this is
a huge difference your results..

May i ask what kernel and xen you are using and if you are doing
something unusual or different to the common way?

I actually have a usb3 controller too, but i would like to keep it to
the dom0 because i'm doing my server backups through it..

I have a Asus Crosshair IV and there are no actuall USB2 drivers for it.. :(
