FreeBSD Port: libusb-0.1.7_1

[ShredZ]

I was trying this logitech applet to get my mouse working in 800 dpi, but 
libusb doesn't seem to find the device. It works flawlessly on linux and I 
was wondering if an easy port couldn't be made of this to freeBSD or 
something alike. I do know programming, but not as much on usb in freebsd.

I got this compiled, but it doesn't seem to notice the correct usb device. 
Since I don't have usb fs I don't know where to look for the device ID the 
mouse gets on bsd.
