USB device (webcam) in XP under KVM

[ss08]

Is it possible to get XP installed with KVM-QEMU to see connected USB devices? There is an option -usbdevice which seems like it will do something of the sort.
I'm specifically trying to get my webcam detected. It works in Ubuntu (Camorama).
My lsusb looks like this:
Bus 006 Device 001: ID 0000:0000
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 003: ID 046d:08f0 Logitech, Inc. QuickCam Messenger
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 026: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader
Bus 001 Device 001: ID 0000:0000

When I give the option -usbdevice 003:046d:08f0 with kvm, I get the error:
Warning: could not add USB device 003:046d:08f0

Any pointers?
