Well there's your problem. You're trying to pull a full amp through the port and the Pi doesn't like it. That's why basically everyone uses a powered hub.

It's odd that it has worked for a month, but is getting flakey now.
I down-speed to 100 and it's working much better.
Thanks

Your issue will likely go away if you use a powered hub. I had similar problems using a cheap POS "powered" hub until I did some troubleshooting and found it was actually pulling the majority of power from my Pi. Up until then it would randomly crash... Now that I have an actual powered hub the problem has gone away. It's not expensive to get a Plugable hub off amazon, like $30.

Agreed - this is a great little USB hub - can easily handle 3 overclocked sticks.

It's not odd, it's lucky. You might have caused some damage to the circuit or it might have cause a fire. USB ports are designed for 0.5A max.

Just kinda wondering why the cgminer compile for windows and specifically the gekko compiled one has a virus attached, i had to disable windows defender multiple times, plus add exclusions to avoid it being deleted. Being new to using the 2pac, I even had to use Firefox to download it as chrome flagged it as well.

windows defender has its head up its ass .

make a folder named mining go to windows defender and exclude the folder named mining

put the cgminer folder in that folder named mining\

problem fixed

My 2Pac has been running well for several months. However, lately it has started to mis-behave.
It will run for 1-2 minutes, and then disappear. It requires me to unplug the USB port and re-plug it back into a different port in order for it to get recognized again.
Plugging into the same port does not cause the 2Pac to be seen, it must be into a different port.

If one port is unusable, how do you make it usable again? I assume it´s a hub? Do you power it off? Or restart the system?

Im running on a RPI3, so it has 4 USB ports.
All I do is stop cgminer with a ^C, unplug and replug into a different port and restart cgminer.
No reboot or power cycle needed.

Hello, my name is Himmbler, I bought two USB recently, today an error appeared and now they do not work. CGminer says failed usb_init (1:40) failed to initialise. I have tested them individually in diferent OS and HUBS and they do not work at all. Any recommendation?
Thank you very much.

I certainly hope you're keeping them cool.

I'm just going to give up and ask ya, sorry Sidehack, I know your busy. What is a good upper threshold temp you like to see on the front board and heat-sink of these gekkos. I'm trying to both avoid damage, and at the same time like all of us I'm guessing trying to provide peak performance with optimal cooling.

Is there a solution for that issue? I get it from time to time, too.

Do you get any HW errors on the zombie going stick? At 200 MHz the voltage pot is at a good position when it´s set to 3 or 4 o`clock.
Did you measure the voltage on the stick?
Did you try this stick alone, without another stick on the hub? I also thought I had a hub with enough power. My power supply is 30 W and I run two sticks on 250 MHz on it. So it should bring 6 A (3 A per stick). But when I turn up my voltage a little higher, there is not enough power.
Maybe turning down the voltage is the answer.
