You need to detach the kernel HID driver and the use "lsusb -vvv" to do that. Once you detach the kernel HID driver you will lose the function of the mouse. But you can re-attach the driver by unplug it and then re-plug it in. It would be nice that usbutils to be changed to automatically detach and attach the kernel HID driver for HID descriptor dumping. -- Xiaofan -- 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
