I think that is a better approach than your patch. Perhaps the zd1211rw
driver could know the VID/PID of the fake CD-ROM to attach to it and send
the fake eject command. The usb-storage (and probably ub) would just have
to ignore the device.
Ok, I've handled the zd1211rw side. Unless I'm mistaken, usb-storage
doesn't currently have a way of blacklisting a device.
How does this patch look?
