[Discuss-gnuradio] griffin powermate on NetBSD

[Greg Troxel]

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:

uhidev0 at uhub0 port 2 configuration 1 interface 0
uhidev0: Griffin Technology, Inc. Griffin PowerMate, rev 1.00/4.00, addr 2, 
iclass 3/0
uhid0 at uhidev0: input=6, output=1, feature=8

poblano gdt 37 ~ > usbhidctl -f 0 -r

poblano gdt 26 ~ > usbhidctl -f uhid0 -a
Consumer_Control.Button_1=0
Consumer_Control.Rx=0
Consumer_Control.Consumer_Control=0
Consumer_Control.Consumer_Control=79
Consumer_Control.Consumer_Control=16
Consumer_Control.Consumer_Control=0
Consumer_Control.Consumer_Control=0
usbhidctl: USB_GET_REPORT(feature) [probably not supported by device]: 
Input/output error

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?
