 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.
