Re: Can you use the USB HID interface within a driver?

Or perhaps someone could point me in the direction of a USB HID driver that does things "properly" already?

Please post "lsusb -v" for your device.

Here's the output. I don't think any of the "class" drivers are suitable, except as templates for interfacing with the main HID code...I think...
