I hadn't tried it yet since I wasn't sure if that was the intended way to start it up within the HID framework since none of the other drivers submitted the urb. Also, submitting the urb requires the usbhid_device structure. Since the usbhid_device structure is defined in usbhid.h, and usbhid.h isn't installed with the kernel headers I wasn't sure if there was a better way to do it (raw events, input mapping or something along those lines). --- Rick -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
