At this point, however, usb_modeswitch is the correct place to put eject
code for all devices.  I wouldn't put this code into udev; I'd put it
into usb_modeswitch instead, since usb_modeswitch is (a) the de-facto
standard, (b) has the most users, and (c) has the most devices.  Yes, it
has problems, but at this point we should fix those problems instead of
creating 5 different eject tools.
