Re: GekkoScience Compac BM1384 Stickminer Official Support Thread
Trying CGMiner now. Getting a "Failed to initiate device" error. It recognizes the devices.
Using ./cgminer -o stratum+tcp://peercoin.ecoining.com:3336/ -u blackbird.2 -p 12345 --compac-freq 150

I would like to help, but I have not seen that error specifically. Can I get a little more info about your setup? What OS, How are you powering, did you rebuild cgminer,etc? Maybe get a little more cgminer output?
I posted a question for you on another thread do you know if I can run older U2's in the same instance of cgminer or can I only stick to the compacs id like to fill the rest of the hub with my older U2's and ahve only 1 pi 2 running them all 
I don't know if they will detect correctly, as the icarus driver specifically can detect anything with approximately the correct chips. You can try, you'd need top build with --enable-icarus and --enable-gekko.
Novak can you provide a diagram showing the voltage adjustment position in relation to voltage I use the flat surface as a guide and with it directly flush with USB port I have been able to get to 250 mhz or so no HW errors I dont have a volt meter handy to test what voltage that brings me up to
Here you go:

So flat edge flush with bottom would be what voltage about?
It would depend which way you turned it. Did you turn right or left and how much? Could be .8 or .55 depending on that or between.
