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.
But I am not so sure if it is a libusb problem or the kernel USB driver
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.

Seems to be quite true.
