Well, the zd1211rw already did that, I wanted to fix that up and was
told to do it in usb-storage instead (which, looking at the diffstat,
seems like a good idea).

I was thinking that I would be able to achieve that by echoing an
appropriate quirk into /sys/module/usb-storage/parameters/quirks,
however, I could not get it to *not* eject the device.
But given that there is already an "option_zero_cd" parameter in
usb-storage, it should be easy to massage this into a general "do not
eject virtual installer media" flag so that people are still able to
get the windows driver files off their devices should they need to do
so.

I'd like them to work with one driver, not two (one in kernel and one
in userspace).

That's a fundamental difference in opinions, and I fear I'm not the one
who is going to decice how this will be handled ;)

Have fun,
