Hi Scott,
we are getting closer. Just a few nitpicks:

We try to keep the list alphabetically sorted. So it should go just
before USB_VENDOR_ID_ELECOM.
Also, the device you sent to me has the PID 0x0732 and is behaving the
same way (need to call the mt_reset command).
Is 0x000a a mistake or do all of your product behave like this?
If it's the latter, then we may purely remove the PID test.
Jiri, any ideas?

As we are on it, this line is more than 80 characters. Tabs are 8
characters length.

spaces instead of tabs.

idem, spaces instead of tabs.
Anyway, I really appreciate your efforts Scott.
