Griffin powermate on NetBSD

I got a Griffin Powermate for testing, as Berndt reports it isn’t
found by the examples on NetBSD. I suspect we need to abstract out
the OS-dependent access and also knob types - this should really be
support of generic usbhidev on all systems. I’ll see what it takes;
NetBSD reads it ok:

usbhidctl: USB_GET_REPORT(feature) [probably not supported by device]:

and the rx and button_1 change with turn/push

poblano gdt 28 ~ > usbhidctl -f uhid0 -a
Consumer_Control.Button_1=1
Consumer_Control.Rx=10
Consumer_Control.Consumer_Control=0
Consumer_Control.Consumer_Control=79
Consumer_Control.Consumer_Control=16
Consumer_Control.Consumer_Control=0
Consumer_Control.Consumer_Control=1

and looping to find changes works:

poblano gdt 38 ~ > usbhidctl -f 0 -l -a
Consumer_Control.Button_1=0
Consumer_Control.Rx=1
Consumer_Control.Consumer_Control=0
Consumer_Control.Consumer_Control=79

Do these devices work on other than Linux with the GNU Radio examples?

Sounds good!

I don’t know. I doubt it, since we open a very linux depending file
to get access to them.

On GNU/Linux I’ve tested with the PowerMate and three kinds of Contour
Shuttle gadgets. The button mapping varies between them, but they
work pretty much the same way. The Contours have what I consider a
bug in their firmware, but our code works around it.
