I've done some major whacking on the usrp host side library that
should solve your problems.

The fast usb classes fusb.{h,cc} are now abstract classes that just
define the desired interfaces.

I've created three concrete implementation classes:

  fusb_generic.{h,cc}: uses only standard libusb routines (works,
     but is slow, at least under linux)

  fusb_linux.{h,cc}: uses linux/usbdevice_fs interface (very fast)

  fusb_darwin.{h,cc}: currently equivalent to fusb_generic; it's
     intended as a starting point for any darwin magic.

I've also added all the autoconf magic to select the appropriate
concrete classes at configure time.

Have at it!
