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