Hans Petter, good day.

I can, but how to relate the device name under devfs to the descriptor
to be retrieved?  I can enumerate all HID descriptors via libusb, but I
can't currently say which device uses them.  And I don't want to torture
users with the crawl over the list of all vendor/device pairs for the
discovered HID descriptors and ask to choose one -- that's not
productive.

Why do you dislike the sysctl approach?  It is simple and reliable.
