libusb provides functions to find what driver is attached to an interface (usb_get_driver_np) and to detach the driver (usb_detach_kernel_driver_np). Using those functions you can detach the default driver (probably usbhid in your case) and then control the device through libusb calls. > In the process of doing this, I updated a couple of perl scripts that > parse sniffusb 1.8 and snoopypro 0.22 plain text logs.
