Add files missed in r194674.

Add libusb 1.0 support which is compatible with the latest revision on
Sourceforge. Libusb 1.0 is a portable usb api released December 2008 and
supersedes the original libusb released 10 years ago, it supports isochronous
endpoints and asynchronous I/O.  Many applications have already started using
the interfaces.

This has been developed as part of Google Summer of Code this year by Sylvestre
Gallon and has been cribbed early due to it being desirable in FreeBSD 8.0
