My gridseed miner uses ST32 Virtual COM Port, and at the moment cgminer-3.7.2 doesn't detect the device. I've updated its driver by zadig, but still no luck. What is the solution to this?
Unplug the power from your hub, start cgminer, and plug the power back in your hub. I have 20 running in cgminer 3.7.2 and that is the only way to get the to work. Chang hotplug in your bat file to 5.
Also in your bat file to start cgminer set hotplug to 5 instead of zero, then with your gridseeds unplugged, run cgminer, after it has connected to pool plug your miners in and you are good to go
