Can we get the HID layer to support duplicating the last usage for controls w/o a explicitly specified usage.
Not having this breaks some devices, most notably Phidget controllers.
I've been using this simple 2 line patch to make them work (though I'm sure it breaks other devices)
It is against 2.4.22 directly, but applies to 2.6.0-test10 (haven't tried against 2.6.0)
Please CC me for I am not subscribed.
