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.
