Does this work for you?  I tried it out but my kernel hangs in early boot if I 
enable the generic PCI controller.  This is my WIP kernel so the problem is 
probably on my end.

I'm trying to boot with

   -device usb-ehci
   -drive id=my_usb_disk,file=usbdisk.img,if=none,format=raw
   -device usb-storage,drive=my_usb_dis
