I have attached an output of domU dmesg and "pcictl pci0 list". I noted
one suspicious line in domU dmesg:

    xen_alloc_contig: XENMEM_decrease_reservation failed!

which comes from _xen_alloc_contig() in xen_bus_dma.c file, line 102.
Maybe this is related to the issue I have after shuting down of the
domU...


Did the USB controller work after this ?


I had to hide also 00:1d.7 (ehci thing) on dom0 boot line. Otherwise,
dom0 would take the control over USB key I tried to connect to USB port
regardless of the booted domU (Linux/NetBSD).

When I booted NetBSD domU (only 000:00:1d.0 imported), this is what I
got on screen:

umas0 at uhub0 port 1 configuration 1 interface 0
umass0: USB 2.0 USB Flash Drive, rev. 2.00/1.00, addr 2
xen_alloc_config: XENMEM_decrease_reservation failed!
umass0: no buffer memory

and domU didn't see connected USB key. Linux domU worked fine under the
same conditions.

Can you try xen-debug.gz, please? Xen should print some information
on dom0 console what is happening.
Maybe if I allow some special logging, it writes something. But if I use "loglvl=all", I won't get anything interesting in "xm dmesg", nor on dom0 console even if I use xen-debug.gz hypervisor. I've attached output of "xm dmesg" command which was run after the NetBSD domU was started, USB key was inserted, then removed and afterwards domU was shut down. It wasn't different from dmesg listing displayed right after booting dom0.
However, I had to rebuild domU NetBSD, because I was surprised a bit when I didn't get XENMEM_decrease_reservation-failed error, but instead, I got some message regarding missing scsibus. I compiled new kernel which contained also "acsibus* at scsi?" and "sd* at scsibus? target ? lun ?" lines.
After booting this domU kernel, I got working USB key in NetBSD domU, see attached dmesg output. The attachment contains the state when insertion of key triggered the XENMEM_decrease_reservation-failed error first time, but not the other times. I also had a one boot of domU when there was no XENMEM_decrease_reservation-failed error at all and key worked immediately (I was able to list directory content on it).
