Hello,
I have two gekkoscience miners. One I bought a while ago and another I recently bought. I was able to successfully run the first miner I got, but I'm having trouble with the second one.
I'm using the version of cgminer that is posted on this thread (the one that is modified for this miner). As soon as I start cgminer, I get an error saying that the miner hasn't submitted a hash for more than 10 seconds. Then I get another error saying that cgminer has tried to restart the miner, but it was unsucesfful due to the error: libusb_sucess. And this error keeps on repeating.
I've tried reinstalling the zadig drivers and have played around with the voltage dial on the miner as well as changing the .bat file configurations. This is my configuration:
cgminer.exe -o the pool I'm using -u my username -p mypassword --compac-freq 170
As I've mentioned I've played around with different clock speeds.
I'm using a powered usb hub (the same hub I used to power the first gekkominer I got). I am not plugging in the two at the same time, so I know it's not some kind of a conflict error or power issue. This miner simply won't mine even when nothing else is connected.
What can I do to fix this error? I'm literally using the exact same conditions as I did for the first gekkominer.
In addition, I noticed that on the back of the gekkominer (where the chip would be on the front side) is a brown spot, almost like a burn mark....like the chip might have been fried. I've included a picture for you guys to see. The bottom one is my original miner for comparison and the one on top is what I recently bought. Should I be concerned with this brown spot?
Here is the link:

I would love some help!
