But how is that file descriptor obtained, i.e. which pathname has been provided to open() initially? You write about libusb: no, sorry, that's not the way to go for STK500v2. It *requires* a plain old serial port, be it physical (RS-232), or virtual (emulated by a driver). Just opening an USB device simply doesn't work. (It would work for other programmer types, like JTAGICEmkII, AVRISPmkII etc.) Only the underlying driver knows how to e.g. talk to the serial emulation device at the other end of the USB in order to adjust baudrates, control signals etc. -- cheers, Joerg .-.-. --... ...-- -.. .
