this feature should be available as soon as 3.0.2 gets released, otherwise you 
could try xen-unstable (but don't know if unstable is stable enough for 
serious work right now) or even xen 2.0.7.

what kind of usb device do you want to have available in your domU? if it's 
"just" a block device you should be able to use the "disk = 
[ 'phy:<device>,<targetdevice>' ]" statement as for any other block device, 
at least in theory ;-P.
