The current CUPS 1.4 USB backend only supports libusb-0.x - the 1.0 APIs are incompatible.

You can try configuring CUPS to use the older kernel USB printer driver:

    ./configure ... --disable-libusb

which uses the older USB backend code for printing on Linux (but is incompatible with HP's software...)
