I can't speak about other distributions, but what I can say is that on 
my system, an installation of Debian testing with both versions of 
libusb installed, hp-check complains that it can't find libusb. My 
system indeed does not have /usr/include/usb.h

So, either:

  * libusb is missing usb.h
  * hp-check is not checking for libusb correctly

Thanks. I suggest to make -r default then.
