GekkoScience Newpac and 2Pac together on Slush Pool

[JohnPainter]

Still learning about mining, for fun. So everything here is posted with a sense of humor and WTF. 

I am running a GekkoScience NewPac miner successfully on my Apple Macbook with OS 12.0.1 and am using a powered Atolla USB 3.0 HUB. I'm using Slush Pool.  My miner is running 100MHz and on my Mac's terminal I see I'm doing about 22.19Gh/s. I'm using Slush Pool and things look good there.  This all seems fine.

However, I'm not sure why, but when I put my 2Pac miner on the same HUB as the Newpac, they are on the same HUB at the same time, the 2Pac is recognized in Terminal on my Macbook, but the 2pac miner is not recognized by Slush Pool.

If I remove the Newpac from the HUB, the 2Pac is recognized in Terminal and by Slush Pool.

I'm stumped why this is happening.

There must be something totally obvious I'm missing as a noob.  Any suggestions what to look at?

TY

Are both miners connected to the same USB in the computer?

If that's the case, probably the USB connector is not able to supply enough energy to both miners at the same time.

Try connecting them to different USB connectors (although they might be connected internally).

Best thing you can do is to connect the miners to a powered USB hub, and then connect the USB hub to the computer.

They are both on the same powered USB HUB (Atolla), there are no USB ports on a MacBook Air, everything goes through one USB C port.  I have a powered dongle with several different types of ports that plugs into the MackBook. The USB HUB is also powered.
 
Thanks anyway, it's a bit confusing with my Mac, I might pick up a PC with Windows 10 and try that as it looks like it that's more common.
