But here's a link to the source directory on one of my 10.0-CURRENT machines, https://dx.burplex.com/src/sys/dev/usb/controller/ Also I've noticed a book on bn.com about FreeBSD drivers, it *might* be good, it's on my 'to buy and see if it's any good' list. Might check it out. -- Waitman Gobble San Jose California USA --bound1363293918--
