It seems that one of my Gridseeds is not actually hashing. See the pic to get what I mean. This is confirmed by my pool speed of barely 3,000 khs.

I rebooted the raspberry several times to no avail. The only difference is that the #Gridseed changes (here is #3, before a reboot was #4).
I got this batch a few days ago and in the first days all 10 were mining.
Now I don't even know how to find the culprit: can i disconnect one by one while they are operating without risking to damage others?
Any advice? tia
@darkfriend77: it was a batch2 from you. Is there a warranty?
it's running just han;t gotten any shares to work on.
give it some time or join a larger pool
