[Xen-users] passthrough issue resulting in device not accepting address 4, error -110

[mikkel@xxxxxxxxxx]

I am trying to passthrough 2 identical pcie cards to domu. Individually it they both work fine, but passing them both through at the same time results in one card not working

Currently xen 4.3.2 (kernel 3.2.0-4)

The cards are 2 dvb tuner cards but act as if they are usb hubs.

from dmesg from domU (debian wheezy 7.8):

[ 60.168106] ehci_hcd 0000:00:10.0: Unlink after no-IRQ? Controller is probably using the wrong IRQ.

[ 107.480174] hub 6-0:1.0: unable to enumerate USB device on port 1
[ 107.492146] usb 1-1: USB disconnect, device number 2

I have found a few similar issues but without any solutions.

Hope some can help.

Cheers

Mik
