Hi, Feel free to post patches here. Some choices you have: Use libusb v1.0 or v0.1 if you need portability. Else use libusb v2.0. All three versions are contained in -lusb on FreeBSD 8+. Sylvestre Gallon had some libusb examples in his USB P4 repositorium. Else if you have questions regarding libusb you can ask either here or at: libusb-de...@lists.sourceforge.net --HPS _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
