Hallo,
the device is working without problems in the dom0, found from parport_pc:
dmesg small2 snip:
parport_pc: ITE8875 found (1P)
parport0: PC-style at 0xf000 [PCSPP,TRISTATE,EPP]
parport0: Printer, Kyocera FS-1700+
parport_pc: ITE 8872 parallel port: io=0xF000
parport1: PC-style at 0x378 [PCSPP,TRISTATE]
snap
to assign this device to a domU I gave the boot-parmaters pciback.hide=(00:08.0)
dmesg found the folling lines snip::
ACPI: PCI Interrupt Link [ALKD] (IRQs *23)
Linux Plug and Play Support v0.97 (c) Adam Belay
pnp: PnP ACPI init
pnp: PnP ACPI: found 13 devices
xen_mem: Initialising balloon driver.
PCI: Using ACPI for IRQ routing
PCI: If a device doesn''t work, try "pci=routeirq". If it
helps, post a report
pnp: 00:02: ioport range 0x400-0x47f could not be reserved
pnp: 00:02: ioport range 0x500-0x50f has been reserved
pciback 0000:00:08.0: seizing device
snap
the pci-device 00:08.0 is still found by the parport_pc modul the printer is
working,
I added the parport modul to /etc/modprobe.d/blacklist
shutdown all domUs and init 6 for dom0
afterwards dmesd small2 found snip:
pciback: vpci: 0000:00:08.0: assign to virtual slot 0
snap
the device-line pci=[''00:08.0''] has been added to the domU
configuration-file
in domU with lspci snip:

snap
in domU modprobe parport_pc
dmesg in domU parport_pc: cannot find ITE8872 INTA
in domU lsmod snip:
parport_pc 33092 0
parport 34120 1 parport_pc
snap
dmesg in dom0 snip:
pciback 0000:00:08.0: Driver tried to write to a read-only configuration space
field at offset 0x60, size 4. This may be harmless, but if you have problems
with your device:
1) see permissive attribute in sysfs
2) report problems to the xen-devel mailing list along with details of your
device obtained from lspci.
