i already came so far in knowing what rivers to load

io-usb -duhci
waitfor /dev/io-usb/io-usb
io-hid -dusb

hidview -R

?
Is there a HID layer library ?

Hi Johan…

Go to this web page:

http://www.ces.clemson.edu/~cvilas/projects/wingman3d/wingman.htm

and you should see something of interest. There is a to-be-published HID
DDK; please send me an email requesting information.

Regards…

Miguel.
