i believe the dmaxl zeus is built with only Gridseed orb and Zeusminer drivers enabled, you would have to rebuild the miner with other drivers enabled to make it work.
(Its been built that way due to issues enabling all drivers at once)

At one point I was running my Antminer U1 on the SHA instance with my orbs, so had to rebuild dmaxl zeus with Icarus drivers enabled otherwise it wouldnt detect.
