So you are out of luck with HID. >From the following webpage, you will know that from pbr333 onwards HID support is removed. http://www.libusb.org/wiki/windows_backend The reason is rather because of the current admin's strong opposition even though may of us do not agree. http://www.libusb.org/wiki/FAQ#CanIcreateadriverlessdeviceusingHIDclass If you want to use libusb-1.0 now, then you will have to use WinUSB driver. Since your device is simple, please use the custom device and not HID device. Renesas provide the libusb example and you can start there. -- Xiaofan ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
