[Qemu-discuss] Patch for setting USB mass storage device (-usbdevice disk) VID, PID serial etc.

[Wicher]

Hi,

Recently I needed to sandbox some software, running it inside Qemu off
of a disk image of the USB stick it came on.
However, Qemu's USB mass storage device emulation (-usbdevice disk)
shows up as a "QEMU USB HARDDRIVE" with VID:PID of 46f4:0001.
The sandboxed software didn't like that at all, and refused to run. So
I patched Qemu to take VID, PID, serial etc. from the command line
arguments, like so:
"-usbdevice 
disk:format=raw:vid=0a6b:pid=0001:manufacturer=Whoever:product=Whatever:serial=324324:/path/to/stick.img"

I'm posting the patch here for other people to find, should they
develop the same VID-faking needs.
I've read http://wiki.qemu.org/Contribute/SubmitAPatch and decided
to not post the patch to -dev as this is a one-off single-purpose
hack, not a proper solution. For instance, with this patch, adding more than one
'-usbdevice disk' type device will lead to spectacular failures. Beware!

Cheers, Wicher Minnaard
