Hello all, I already posted this in the newbie section though to get the proper exposure I'm posting it here..

A co-worker and myself recently picked up two of the Satechi 10 port hubs to test out some of the ASICMiner USB Block Erupters and seem to be having nothing but issues so I was wondering if anyone else out there has used them with success?

Basically the situation goes like so:

With one block erupter it will run for a little over an hour and then I'll get the solid green light and CGMiner spams Comms Error.

With two or more block erupters they run for maybe 30 seconds if that and then I get solid green lights on random units, sometimes they will come back online and then just go back offline, same deal with CGMiner spamming Comms Error.

I then took my D-Link DUB-H7 hub and connected it to the Satechi 10 port with one erupter in the D-Link hub and now it has been running for days without issue.


I have the same behavior from pluging 8 Eruptors on a black Anker 10 ports hub. Maybe software could workaround the situation as:

1. if you wait a couple of minutes, the miner exit that state.
2. Restart cgminer does the trick as well
3. Unplug/plug the faulty miner fix it also.
