[Xen-users] USB devices in dom0 failing to accept address

[Andy Hawkins <andy@xxxxxxxxxxxxx>]

Hi all,

Have a Debian Wheezy system with the Xen and XCP packages installed. When I
first installed Debian, the USB keyboard and mouse all worked Ok.

After installing Xen, the USB devices stopped working. Now, even with
nothing plugged in to the USB ports, I still get the following errors during
boot:

[   39.193178] usb 3-1: device not accepting address 3, error -110
[   39.305178] usb 3-1: new high-speed USB device number 4 using ehci_hcd

[  112.730619] hub 4-0:1.0: unable to enumerate USB device on port 1

It's not the end of the world at the moment, as I have no USB devices
plugged in. However, I might want to connect USB hardware in the future, and
it would appear that this won't work.

This is a 32 bit dom0, with all 64 bit guests (I saw recommendations to
install this way).

Linux xcp 3.2.0-4-686-pae #1 SMP Debian 3.2.46-1 i686 GNU/Linux

The xen hypervisor is 64 bit, v4.1.

Any suggestions?

Andy
