Hi,

I am sorry to say that I mixed something. What does work now is 
2.6.31.13 kernel. The error
messages are gone now for 2.6.32.11, but it is still not functioning. 

So, with the 2.6.32.11 kernel, it will not recognize the same USB 
controller that is recognized 
by 2.6.31.13. 

When booting:

[    0.325746]   alloc irq_desc for 503 on node 0
[    0.325753]   alloc kstat_irqs on node 0

When I detach and attach from Dom0, it will log in the DomU:

[  224.237069] pcifront pci-0: Creating PCI Frontend Bus 0000:00

In Dom0 we have:

pciback: vpci: 0000:00:02.1: assign to virtual slot 0

For reference, the log entries when I detach/attach the device in 
2.6.31.13:

Did so and move to Xen 3.4.3-rc4 and latest 2.6.18.8 Dom0 kernel. It 
works now with pvops 2.6.32.10 DomU kernel!!! 

Thanks Pasi!!!

Eventually, you may put on the Wiki Page an example with more than one 
PCI device, so that hectic persons like
me see better that a) it's without parenthesis and b) a comma separated 
list ;o).

BR,
Carsten.

I thought so, too, but this doesn't work either. And: it does work in 2.6.18, as
I think it's not realy two devices. One is OHCI, the other EHCI.

BR,
Carsten.

Maybe both of these devices need to be passed through at the same time to the same guest, 
since they're part of the same device?
