[libvirt] Can't Pass Through USB Device To Ubuntu 9.05 Guest OS
Greetings!
I created Bug 504444
<https://bugzilla.redhat.com/show_bug.cgi?id=504444> which is partially
quoted in this post:
----------------------------------------------------------------
Coding this xml:
<hostdev mode='subsystem' type='usb'>
<source>
<vendor id='0x0403'/>
<product id='0x6001'/>
</source>
</hostdev>
should let my Ubuntu 9.04 guest have access to the device, which in this case
is a USB-to-Serial UART (based on an FTDI FT232RL chip.) However the guest does
not "see" the device or recognize it in any way. It does not show up in the
guest's /var/log/messages or in the output of lsusb. I would like the guest to
have access to this device.
This is what virsh seems to be seeing:

Version-Release number of selected component (if applicable):

Any suggestions for fixing this problem? Is there a clear procedure for
getting a Fedora virtualization guest to recognize a USB device?
Thanks for your help!
