If you are SSH(putty) into a raspberry pi the "Smart" power management may give problems to that connection also..
I'm logging into my RPI 3 "headless" using putty from a Win 7 CPU on my local net. Just got my new sticks running last night *yahoo* - and after my Win 7 CPU "slept" all sticks were not hashing next morning.
I'm running six Moonlander2s on two "Plugable" 7 port Charging/Data Hubs. I inspected the board in these and they DO NOT have three control chips on them. 1,2,3 are on one chip and 4,5,6,7 is on a second. I think these are a newer model where they have planned a cheaper way of making them. We had extra time waiting on shipping so I also ordered six "Y" USB cables, they are 12" long with two male ends - one is Data & power while the other is only power - they both go to a USB female socket for the Moonlander2 to plug in. Hoping I now have up to 3 Amps available for each stick. The RPI is loaded with Raspbian Stretch-Lite. I'm still running stock except for clocking to 756 and raising diff to 256. I WILL be tweaking these up over time.
Is it true that default diff of 128 is best for running one stick and we need to raise this some when running multiple moonlanders (like my example of six)?
Thanks to jstefanop for all your efforts & wish me luck with mining *red-flash* *red-flash*..
Thanks also to Astrali for the Raspberry pi guide - helped me a lot..
