I forgot one important thing. Your program (or libhid) detaches the kernel hid driver, but it is better to re-attach the driver back one the program exits. By doing this, you will lose your USB HID mouse or keyboard (or need to unplug and plug) if using your program. I am not so sure about libhid. But libusb-1.0 has such function. http://libusb.sourceforge.net/api-1.0/group__dev.html int libusb_detach_kernel_driver (libusb_device_handle *dev, int interface) int libusb_attach_kernel_driver (libusb_device_handle *dev, int interface) -- Xiaofan http://mcuee.blogspot.com -- 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
