Hi all,
I was looking through some archived posts in this forum, and noticed a few
people mentioning having to use trial and error when trying to use PCI
passthrough to get a USB root hub passed through to a HVM domU. I thought
I''d share something I noticed which made this much easier for me.
Say I wanted to pass through a root hub which has my USB Plantronics headset
connected to it. The ''lsusb'' command shows me that the device
is on the following:
Bus 011 Device 006: ID 047f:c006 Plantronics, Inc.
It also shows me the root hub for Bus 011:
Bus 011 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
You can then run the following command, either as root or via sudo:
# lsusb -s 011:001 -v | grep iSerial
iSerial 1 0000:00:16.0
And the PCI id is 0000:00:16.0
Hope this helps,
David
