Sending generic USB messages?



I have a device which shows up as a generic HID, but where the actual
protocol defined is just to poll it with queries and get responses.

None of the IOHidDeviceInterface functions seem to offer a way to
just send requests to and from the device.  I don't need to monitor queues,
or extract x and y values; none of those are applicable.  Is the HID driver
even going to allow this?  If not, how do I prevent the OS from attaching
the HID driver?

(On NetBSD, I'd do this with ioctls on /dev/uhid0 or /dev/ugen0.)
