Rewrote the program to use poll instead of select (which does fit libusb better even if I like select better generally) nothing else changed only poll instead of select. => Works like a charm So to sum it up: select + libusb seems not to work, poll + libusb works however. So is this a general FreeBSD select vs. poll issue or just with the USB stack? How can I help debug this further? Regards Peer Stritzinger
