If I was forced to make a wild guess I'd probably assume it uses some USB-HID
interface for configuration, and udev for hotplug detection.
I think I'll have the libery of including Mr. Schroer in this discussion :)

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.
Hmm, I wonder why it cares about udev? When I saw "enumerate" I thought this
was a libusb thing, but clearly not.
I thought that FCD devices just "manifested" as audio anyway--no direct libusb
required?
