The problem is that Ubuntu 12.04 seems to carry 1.0.9 around, so this seems strange.
I'm a bit conflicted -- the missing symbol looks like it should belong to libudev and not libusb-versionhell.
This might indicate that you're bound to update libudev, which is rather system central, and which might be a bit of a hassle; I'd personally recommend updating to Ubuntu 14.04 LTS or the brand new 14.10 [1].
It feels like the module should link against libudev, as it includes libudev.h and uses symbols from that library, but I can't find a single reference to udev in the cmake files of gr-fcdproplus.
this is but a shot in the dark, but could you delete the contents of your build folder, and rund cmake with "-DCMAKE_CXX_FLAGS=-ludev"

I use ubuntu 12.04 and libusb-1.0-0-dev
Do you what version of libusb is compatible?
I think that 1.0.9 and newer are compatible.
