To start my bitcoin mining experience I have purchased the bitcoin merchant 3x Gekko Compac F combo with Raspberry Pi 4 preinstalled with cgminer.  I want to set each mining stick as a different worker on slushpool.  I enter the following terminal commands:

cd git/vthoang/cgminer
sudo  ./cgminer -o stratum+tcp://us-east.stratum.slushpool.com:3333 u myacctname.palermo1

Terminal responds showing 3 chips ramping up to 200-300 h/s each

Switching to slushpool shows one Worker named palermo1, status OK ramping up to 302.8 GH/s scoring hashrate.

This appears to be only one chip working???  All three sticks are blinking and working minimal heat.  How do I change my code to get three workers running around 300 GH/s each?

Help appreciated as I am having difficulty learning to do this.
