That should work as well and probably even better.  I'm not up-to-date
on the (in)compatibility of pkg-config and pkgconfig.

I know *nothing* about how homebrew works, but that formula seems to use
libusb-1.0.21 so that should be fine.

With those two changes to the homebrew formula for sane-backends you
should be all set to build with USB support.

Hope this helps,
