I'm having trouble getting kvm/qemu (I honestly don't know where one starts
and the other ends) to pass USB devices through to a win2k guest.
I'm running Ubuntu Gutsy, and have tried with both the Feisty kernel I
usually run (long story, SLUB is causing me other issues) and the stock
Gutsy kernels (2.6.20-16-generic and 2.6.22-14-generic respectively). I
used module-assistant to build the kvm modules for each. I then made sure
the usb proc fs was mounted.
On 2.6.22-14-generic I have kvm and kvm-intel loaded and start with:
$ sudo kvm -no-acpi -usb -usbdevice host:1390:0001 -m 750 -cdrom /dev/cdrom
win2k.img
I get the following message repeated in the syslog:
Jan 5 16:36:16 Aeon kernel: [ 4872.440000] usb 5-1: usbfs: USBDEVFS_CONTROL
failed cmd kvm rqt 128 rq 6 len 64 ret -110
Windows boots to the desktop and I am able to see the TomTom via the qemu
monitor:
(qemu) info usb
Device 0.0, Speed 480 Mb/s, Product TomTom GO 720
>From within win2k, the device manager shows 1 "USB Device" without a
driver. When I try to reinstall the driver I get an error that the
installation failed, and the USBDEVFS_CONTROL messages reappear in the
syslog. Can anyone shed some light on what the problem might be? Does
anyone have any kind of a usb device working on a win2k guest?
Thanks!
