Recently acquired a R606 from Eyeboot and been running fine for several days, with Pi 4 and Server PSU + breakout.
I check pool status regularly and noticed hashing stopped. Restarted Pi 4 and power cycled R606 but hashing will not start anymore.
Appear to be detecting only 9/12 chips. Is unit faulty?
