It is the error code the kernel returns when there is a short packet

a completion status, not as a submission error code.
I think the important thing is that it is unique so that we can detect
the condition easily.
Is this sufficiently unique?
Yes, sounds that way.
I like David's suggestion of preserving the old meaning of
USBDEVFS_URB_SHORT_NOT_OK.
I seriously doubt that any user programs employ it. Certainly nothing
using libusb does.
OK, either way works..
