Yeah, cable is fine now.

But another issue I have with Rpi4.

I have Rpi4 Umbrel LN running with BTC ssd full node connected to RPi usb3 port.

When I connect to the second usb3 port BTC miner,

I am getting:ls: cannot access '/dev/ttyACM*': No such file or directory

But when I disconnect BTC ssd usb3 and keep just BTC miner

umbrel@umbrel:~ $ ls /dev/ttyACM*
/dev/ttyACM0

Somehow when I use rpi4  with 2 usb ports. one for ssd full node and another it does not work.

I have another Rpi running LTC moon 2, but its 32 bit. It would be nice if ver for 32 bit will be available.

Thank you

Check your power adapter.   Many times with RPi's there is not enough power to power all of the IO ports.   

I use the Canakit RPi  3.5Amp adapter on mine that is running two USB ports with LTC Moonlanders and Gekko hubs on each. 

Also you should disable with Wifi power management if you are using Wifi - I have seen issues with some mining apps with Wifi that goes into different power states.



Yep, second this! Especially with the RPi4, power is VERY important. Make sure it's got a power adapter with enough amps to supply it or you'll run into all sorts of issues

With new adapter for  3000Amp designed for RPi4 does not work, just tried.
