I was getting link errors...nothing referenced symbols in the libusb library at the time it was linked in, so it was ignored. The fix is simply to rearrange the order of the libraries and source code on the GCC command line.

My OS is Linux Mint 13 Maya, my toolchain is Linaro GCC 4.6-2011.10 installed using the summon-arm-toolchain script. The following was the output of make:
