[Bug 494291] [NEW] kvm: xp won't talk to USB device with host linux-image-2.6.31-16-generic

Binary package hint: kvm

Trying to get a Ross-Tech pc->car interface working under Ubuntu's
generic kernel image.

Works fine with the kvm-88 image I've compiled myself on my machine, I
have issues with the generic ubuntu image.

I start my windows XP VM image:
sudo qemu-system-x86_64 \
    -m 1024 \
    -drive file=/mnt/images/xp-base.qcow2,if=virtio,boot=on \
    -net nic,macaddr=e0:91:a6:33:28:02,model=virtio \
    -net user \
    -vnc 127.0.0.1:1 \
    -usb \
    -usbdevice tablet \
    -monitor stdio

then i add my USB device:
(qemu) usb_add host:0403:fa24

XP realizes the device is there, but when I try to use my car
application in XP, it times out trying to communicate with the device.


Now, if I boot Ubuntu and specify my KVM-88 kernel in grub2, *everything works great*.
I've attached a diff between Ubuntu's kernel config and the KVM-88 config that actually works.


Any ideas on what this could be???
