I have a raspberrypi 4 that I have connected to a powered USB hub with 7 2pac usb miners. The problem that I am having is that from what I can tell is that the pi reconises that the miners are plugged into it but it doesn't know what they are. I've tried this code
Code:
cd ~/git/vthoang/cgminer/
sudo usermod -G plugdev -a `whoami` sudo cp 01-cgminer.rules /etc/udev/rules.d/
sudo reboot
but it doesn't change anything all keep getting is
Code:
pi@raspberrypi:~/mining/2pac/cgminer $ ./cgminer -n

If anyone knows something to fix this either updating the miners themselves or whatever but any help or lead would be appreciated.
