Good Evenight
I try to do working usb's into domU xen guest, SO of xen server is Debian
Squenze 6.0, into HVM guest usb works and can make use but with
ParaVirtual guest PV can find this devices with lsusb or into /dev/
directory.
Kernel load into xend and guest is the same and is the kernel provided by
this package:
ii linux-image-2.6.32-5-xen-amd64 2.6.32-35
Linux 2.6.32 for 64-bit PCs, Xen dom0 support
ii linux-image-xen-amd64 2.6.32+29
Linux for 64-bit PCs (meta-package), Xen dom0 support
this is the version of kernel:
Linux version 2.6.32-5-xen-amd64 (Debian 2.6.32-35) (dannf@xxxxxxxxxx)
(gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Tue Jun 14 12:46:30 UTC 2011
Configuration of PV guest domain is:
bootloader = '/usr/lib/xen-default/bin/pygrub'
vcpus = '2'
memory = '512'
root = '/dev/xvda2 ro'
disk = [
'file:/disco/xen/maquinas/domains/debian-prueba/disk.img,xvda2,w',
'file:/disco/xen/maquinas/domains/debian-prueba/swap.img,xvda1,w',
]
name = 'debian-prueba'
vif = [ 'ip=192.168.0.200,mac=00:16:3E:D2:D7:46' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
usb=1
vusb = ['usbver=2, numports=10,port_1=1-3,port_2=1-2'
oput get in XEN whi xm about usb is the next info:
root@xen-servidor:/etc/grub.d# xm usb-list debian-prueba
Idx BE state usb-ver BE-path
0 0 1 USB2.0 /local/domain/0/backend/vusb/17/0

root@xen-servidor:/etc/grub.d# xm usb-list-assignable-devices
1-2 : ID 0402:5661 ALi Corp. Audio Player
root@xen-servidor:/etc/grub.d#
kernel of this PV domain "debian-prueba" is next:
root@debian-prueba:~# cat /proc/version
Linux version 2.6.32-5-xen-amd64 (Debian 2.6.32-35) (dannf@xxxxxxxxxx)
(gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Tue Jun 14 12:46:30 UTC 2011
root@debian-prueba:~#
but into this guest domain "debian-prueba" when exec lsusb command get
nothing, see below:
root@debian-prueba:~# lsusb
root@debian-prueba:~#
at dmesg of this PV domain, can watch only this info about usb and xen:

Anyone have the same situation with PV guest domain working with usb throw
PVUSB techonology, can anyone guide me to make run usb at this domain,
need connect four devices 2.0 (printer, disc, scanner and modem with
serial port throw usb-serial converter)
If any one can help me, because i read something about PVUSB but can't
make work usb at PV domains or not know steps to do this devices work.
Thanks and Best Regards.
Nacho Alegre.
