@krakers I connected the device to the XenHost Physical, Enabled Passtrough for this device and attached it to the VM Guest and booted it.

Hi,

I'm trying to connect a Serial to USB device to my Debian VM in Xen.
The Xen Host sees the USB correct:
Bus 002 Device 006: ID 05d1:1011 Brainboxes, Ltd

but in the VM it shows as van HUB:
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

it doesn't seems to connect to a device path like /dev/ttyusb0.
I couldn't find any solution to get this working.
