Hi Matt,

Two comments come to mind:

(1) Is it correct that changing this would involve no more than:

* Linux 2.4.? kernel updates:
    - drivers/usb/usb.c ... usb_match_id()
    - drivers/usb/ibmcam.c ... uses range matching
    - drivers/usb/storage/unusual_devs.h ... lots of ranges
* Hotplug scripts
* "usbmodules"
* No spec/documentation (yet)

Distributions would need to get all those updates at once;
I don't know how much of a problem that'd be, except
that if there's no coordination then it'll be painful.  If it
happens, this should all be ready at the same time.  (Not
like the original match_flags patch ... though goofing this
up would break less, since "modutils" will still work.)

(2) For some reason my preference in this area would
be to use "low <= value < high" range specs rather the
current "low < value < high" or "low <= value <= high".

That's just a better match to how I normally think about
such ranges -- not a huge deal, but it seems like Jeff
Ozvold had a similar thought.  So maybe I'm not alone
in thinking about those bcd version codes that way.
