This has nothing to do with persistent device naming, and the core of
udev can not be made device specific. It's installed on all
architectures and systems, and therefore such hardware specific
matches can not be in the default rule set.

Udev rules must not call any tools from /usr. Some packages do that,
but the main udev package should not do that. Note, that I absolutely
don't mind if people do that, because I think /usr must _never_ be on
a separate partition.

Also the main udev package can not ship hardware specific rules,
nobody will care about them, and they will no be maintained here and
just bit-rot. Maybe it can go into the usb_modeswitch package, which
does this eject thing for many other devices?

Thanks,
Kay

Thanks for your input and the rule has been integrated into usb_modeswitch 
package.
