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.
