You haven't given any information about your distribution. Assuming it is 
RPM-based and your libusb is installed as an RPM instead of source, you may 
be missing the development package for libusb. Depending on your distro, the 
package may be named something like "libusb-devel" .

Also make sure you don't have any part of an older version of hpoj installed.
