Hopefully Wander or other Python experts can help you now that you have a detailed log. > ====================================================================== > ====================================================================== > ./mylibusb_example > with #define LIBUSB_DEBUG 3 > which doesnt gives too much info > ====================================================================== > ====================================================================== > Buscando: VID=451, PID=3410 > --> VID=451, PID=3410 > --> vendor=UTICOM Diego > --> product=USB2Serial +4GPIO > Encontrado. > Kernel driver detached. > Lectura realizada REQUEST_LINE correctamente.

Estado: 0xff > In order to have more log message from libusb-1.0, you may want to rebuild libusb-1.0. Download libusb-1.08 and then rebuild it with the following option "./configure --enable-debug-log" and then install it. Rebuild your C example and then you should be able to see more debug logs for both of your pyusb and C examples. Then you can check if they really send out the same thing on the wire. -- Xiaofan http://sourceforge.net/projects/libusb-win32/ ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
