libusb is the cause of the problem.

I should have thought of this sooner.

The best and final (I think) solution is to add --disable-libusb to the
configuration options in cups-base/Makefile and rebuild.

I tested this on 8.0 rather than 7, and didn't try printing, but I
verified that the USB backend sees the traditional /dev/ulptx
device rather than using libusb, so I think it will work for you.
