Here is my udev-rule that unbinds the hid-driver when it matches the (my) vendor, product and interface1 ( $id:1.1). If you device has more than one interface, I guess you have to create a rule for each of your interfaces. -------------------------------------------------------------- ATTRS{idVendor}=="07c0", ATTRS{idProduct}=="1114", PROGRAM="/bin/sh -c 'echo -n $id:1.1 >/sys/bus/usb/drivers/usbhid/unbind'" --------------------------------------------------------------- Eberhard -- 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
