CGminer not detecting antminer U2

[n1ght5had3]

so im a hobby miner ive got a redfury which ive been using for ages and decided id get a u2
i used ZADIG to install the drivers for the redfury and U2.
cgminer detects and uses my redfury but the u2 doesnt show up at all

its driving me nuts
does anyone know what could be wrong?

Have you tried hot plugging it? Fire up cgminer and then plug the U3 in and see if it finds it.
