qemu usb storage emulation
--------------------------
QEMU has two emulations for usb storage devices.
QEMU has three devices for usb storage emulation.
Number one emulates the classic bulk-only transport protocol which is

Number three emulates the classic bulk-only transport protocol too.
It's called "usb-bot". It shares most code with "usb-storage", and
the guest will not be able to see the difference. The qemu command
line interface is simliar to usb-uas though, i.e. no automatic scsi
disk creation. It also features support for up to 16 LUNs. The LUN
numbers must be continous, i.e. for three devices you must use 0+1+2.
The 0+1+5 numbering from the "usb-uas" example isn't going to work
with "usb-bot".
