Linux USB kernel drivers in userspace daemon

Webcamd is a small daemon that enables about 1500 different USB based
webcam, DVB and remote control USB devices under the FreeBSD operating
system.
The webcam daemon is basically an application which is a port of Linux USB
drivers
into userspace on FreeBSD. The daemon currently depends on
libc, pthreads, libusb and libcuse.
