Re: [libvirt] [PATCH] usb: allow host devices to be specified by port
Thanks for the patch. Sorry this didn't get a timely response. Note there's an
upstream bug for this as well but it doesn't add much:
https://bugzilla.redhat.com/show_bug.cgi?id=914883
The patch is a bit difficult to review because it's mixing up some
refactorings in virhostdev.c with the functional additions. Please separate
the refactoring and submit it separately, before the functional changes.
Also missing is docs/formatdomain.html.in extension, which can go in the patch
with the functional changes. We can help with that though if you don't want to
wade into editing XML.

Previously, only VID/PID and bus/device matching were supported.
Neither
of these provide a stable and persistent way of assigning a guest a
specific host device out of several with the same VID and PID, as device
numbers change on every enumeration.
Add a third method of matching, bus/port, which allows a specific port on
the host to be specified using the dotted notation found in Linux's
"devpath" sysfs attribute.
Is there any way to determine the host port outside of checking sysfs? Some
'lsusb' switch that makes this easy to lookup?
Thanks,
Cole
