I've been toying with about 10 moonlander2's for the past few weeks and have noticed a trend.
several have declining hash rates, that is a device will start at say 4.68 Mh/s and with every refresh the hash rate declines a little until the device is hashing a a few hundred Kh/s or in some cases 0.0Mh/s.
im using two systems to test a RasPi3 with a 49 port block eruptor USB hub and a win 10 Pc with A 13 port Anker hub.
I don't think I have a USB power issue.
HW error rate is under 2.5%
Also I never get the ASIC has stopped hashing message, just a slow decline.
Thoughts or ideas?
