Hello everyone, newbie here.

I was wondering if anyone else was having issues with cgminer looping the "GSD X failure, disabling!" indefinitely when you try to run more than one 2Pac. I have been able to get up to 2 running simultaneously by plugging them in sequentially while cgminer is running, but any more than that and it ZOMBIEs the last one I plugged in and gives me the "failure" message over and over as it tries to find successive sticks.

Anyone seen this and/or figured out a cure? I would like to get more than one stick running at time!

Just for reference:
- I followed the instructions in this post to compile my own build (Windows) so it's current (and works just fine with the single stick)
- My USB hub is externally powered and I have tried multiple hubs and configurations - I don't think it's a power issue
- I've tried running each stick individually, so it's not a bad stick

Any help would be appreciated!


What is the hub you are using?

I've tried on an Anker 10-port 60W 3.0 hub (https://www.amazon.com/gp/product/B00VDVCQ84/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) and on an Anker 7-port 2.0 hub (https://www.amazon.com/gp/product/B00R5ZA20G/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1).

But I've also tried just plugging two into my computer directly and I have the same issue.

Check out this note by NotFuzzyWarm on the hub thread:

Perhaps the hub internal layout are similar?
