Could you be a bit more specific? I know there are some missing calls in FreeBSD. And I have problems with libusb interrupt write with the default kernel (hangs). It is documented here. http://lists.freebsd.org/pipermail/freebsd-usb/2007-November/004128.html But I am not so sure if it is a libusb problem or the kernel USB driver problem. The HPS stack seems to be better in this aspect and I got some libusb application ported from Linux/Windows to FreeBSD thanks to the help from Hans. > The current stable version of libusb certainly makes a lot to wish for > on FreeBSD. > Seems to be quite true.
