Hi ,

We were using Linux's pci-passthrough . We are trying to make USB
controller available to domU.
Both domU and dom0 are compiled from scratch such that PCIback is
enabled in dom0 and PCIfront is enabled in domU.

1. After having hidden it from dom0 ( Late binding method )

echo -n '0000:00:1f.2' > /sys/bus/pci/drivers/uhci_hcd/unbind
echo -n '0000:00:1f.2' > /sys/bus/pci/drivers/pciback/new_slot
echo -n '0000:00:1f.2' > /sys/bus/pci/drivers/pciback/bind

2. We made it available to domU by putting
pci = [ '0000:00:1f.2' ] in its config file.

3. Now, USB controller remains listed under lspci and
/proc/bus/pci/devices in dom0

4. But /proc/bus/pci/devices is empty in domU.

I am doubtful if step4 is expected behaviour ? How do we test it?

Looking forward to hear from you ,

Shase, CM
