pciback.hide

[Alex Poylisher <sher%komkon.org@localhost>]

I am trying to make a USB port on an IBM T61 available to a Windows XP domU.

Is pciback.hide the right means to hide a device from dom0 with -current
and Xen 3.1.3?  If so, could someone knowledgeable please tell me what is
wrong with the following setup? If not, what is the right way to hide a 
device?

Thanks,
