I finally got minera up and running after days of trying (the SD card i was using was corrupted). WISH I HAD DONE THIS EARLIER!

Now I am running into a problem which I don't know is actually a problem or me just being a n00b pl3b, but as the subject line reads, my gekko's are not being recognized by minera.

My current set-up is Raspberry Pi 3 (B), 12-port usb hub, 3 Antminer U2's (all running as expected) and 2 Gekkoscience rev2.
I'm currently using cgminer with options "--anu-freq 250 --compaq-freq 150 --retries=1"
The 2 Gekko's don't even show under the devices. There was 1 instance where ONE of the Gekko's showed up (I'm assuming it was the Gekko with device # AMU0 (as opposed to Antminer ANU#)) but it was running at around ~220 MH/s...
I unplugged and plugged back in the both of them, and then it was back to square one with none of them showing up. I've tried using every possible usb slot I have as well. Both devices light up green when plugged in but that's it. Any suggestions??

I wanted to install cgminer-gekko but I'm not too comfortable with the custom stuff yet.

Any help would be greatly appreciated. In the meantime I luckily bought an extra RPi for sand box testing so I'll just install Raspbian on that for now for my Gekko's.
