Sure, that's as easy as enclosing lines 447-526 in an "if" test for
The reason I tested for the USB libraries unconditionally is that I
thought in the future, we may want to go the opposite route: if
neither --with-usb nor --without-usb is given, then check for the
requisite libraries and enable USB drivers by default if they are

"all" means "the user has not requested any particular specific
drivers". If you really want to build all drivers, then specify
