Reverting to libusb-0 (even statically linked) is a quick
fix. Debugging of libusb-compat, fixing it and sending patch upstream
is a correct way.

Up to now it worked in all cases except gnuradio, which uses internal
functions of libusb-0. All other applications should work with
libusb-compat and no static linking should be needed.

Maybe few years from now on we can drop libusb-0 recipes completely (and
keep gnuradio with statically linked old library maybe forever)
altogether with the virtual. Now it is useful for quick fixing and for
debugging of problems of libusb-compat.
