...having endless trouble trying to get my 37 DM 2.0 rig with 5 Orico ten ports running with rasp pi. I followed all steps correctly, ensured that the pi was not buggy (interchanged it with working 5 chip rig), and don't seem to have any connection happening (no lnk light) via Ethernet to ssh with putty.
Any ideas much appreciated.
Ps anyone have luck with 30 plus dms on windows dualminer software?
I had a heck of a time just getting ten goin stably....
I have 29 working and completely stable on a Raspberry Pi with the dual miner cgminer and mineninja. This sucker will run for weeks on end without any problems. My current uptime is nearly 15 days. It's much better than my GridSeed 5 chip rig which I've found to be much less stable, and a pain to set up and tune.
One thing you have to be very careful about is making sure that you don't have more than 9 DMs in an Orico.
Also, due to the underlying Orico sub-hub layout, you have to leave the slot nearest the power switch empty. This is absolutely critical. If you leave the wrong slot empty, you're going to see stability problems. So you should follow the diagram on this thread or the DM site exactly.
Regarding your connection to your Pi, that sounds like a fundamental Ethernet problem and unrelated to the DMs or any USB problem. If you don't see a link light, it could be anything from a bad Ethernet cable, to a bad switch, to a damaged Pi.
