There is some progress.  I've sent PR usb/103418 containing a patch to
usbhidctl(1).
You can test the patch if you have a hid with a known output descriptor:

# usbhidctl -f /dev/uhid0 -w name=value

should do the trick.

When I test the patch with my Xbox 360 controller which contains a
reverse-engineered output descriptor it crashes when calling
hid_set_data() from libusbhid.  I guess I'm not initializing the
variable *buf correctly (it contains 0x800).

Alternatively you can import usbhidctl(1) from OpenBSD/NetBSD (some
trivial patches are needed, like s/hid_start()/hid_init() ) which has
hopefully a working -w option.

Regards,
Rene
