Re: [Xen-users] Re: use usb isdn modem in guest

What you'd need to do is use pciback.hide on dom0 kernel line to hide the
pci card from dom0, and add a pci = [ <pcicard id> ] section in your xen
domU config. You can use lspci to find out the pcicard id.
I overlooked that you are using usb, in which case you'd probably be
best off
to dedicate an entire usb card to the domU since usb front/back drivers
have
not been implemented for recent Xen versions.
Due to my own tests, usb is possible if you pciback.hide a complete controller
chip.
It might also work with only one controller, but I never had success in
functional usb communication
and system stability by doing so.
As an example, my desktop's lspci shows

i would pciback.hide=(00:1d.0)(00:1d.1)(00:1d.2)(00:1d.3)(00:1d.7)
additionally, i would also blacklist the usb modules (or at least usbcore) in
dom0
by e.g.
echo "blacklist usbcore" >>/etc/modprobe.d/blacklist
