[Xen-devel] Problem passing a HP-DAT (USB) device to domU

[Matthias Wolf <matthias.wolf@xxxxxx>]

Hi specialists, 

I'm trying to pass a HP Surestore USB-drive to a domU. I'm hiding the
pci-device in the dom0, capturing it in the domU, and rceive the
following lines in /var/log/syslog of the dom0 after a reboot: 

=======================================================================
Aug  8 00:04:49 localhost kernel: pciback 0000:00:1d.7: Driver tried to
write to a read-only configuration space field at offset 0x54,
size 2. This may be harmless, but if you have problems with your device:
Aug  8 00:04:49 localhost kernel: 1) see permissive attribute in sysfs
Aug  8 00:04:49 localhost kernel: 2) report problems to the xen-devel
mailing list along with details of your device obtained from lspci.
======================================================================= 

I'm not quite sure what I'm expected to do in the /sys-tree: root has
write-permissions all the way down the branches. 

I'm using the stable version of the xen-hypervisor 3.0.3-0-2 (debian). 

I kind of *need* this functionality and would be very grateful for any
kind of help or hint. 

Thanx in advance, 

Bests from Vienna/Austria

pS.: THANKS a whole lot for such a fine piece of software!
