USB Passthrough Seen as Root Hub in VM
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.
What you see in VM is not your device. Did you enable Passthrough for device and then attached it to VM?
@krakers I connected the device to the XenHost Physical, Enabled Passtrough for this device and attached it to the VM Guest and booted it.
@johanb7 I had the same problem in the past with FTDI-based USB device. I could see it in Xen host, but not in VM. I've spent many evenings trying to make it visible in VM, but with no luck though.
I don't know why, but seems that some USB devices won't attach to VM.
