Re: GekkoScience 2Pac BM1384 Stickminer Official Support Thread

I'm having some issues with a 2Pac, wondering if anyone has any ideas...

Was working fine; PC rebooted unexpectedly, and now I cannot get cgminer to recognize it. (have tried multiple PCs, fresh installs, etc.)
-Green light stays illuminated
-Windows recognizes device - shows in devices and printers
-when i run cgminer.exe -n, it finds device, and lists as GekkoScience 2PAC Bitcoin Miner
-when cgminer.exe is run either via batch or just launching the executable - always states 'No devices found' (cgminer build is confirmed working with other 2Pacs)
-have verified and re-installed winUSB driver via zadig 2.3
-checked with mutimeter - pulling 0.02a, 5v, 0.217w

any ideas or assistance would be greatly appreciated.

Thanks,
CJ

Hi, just to clarify! You have 3 Sticks, 2 are working in the same Computer and with the same Cgminer (VH's) version, but 1 stick is not working? is that so?

There were 2 devices running on this machine at one point, one of those devices is no longer being used. The single stick that I have currently was running on this PC without issue prior.
Thanks,

For some reason sounds like the chip is not getting enough power to run anymore.
Move around the PC and try a port on a different controller or use a powered hub (recommended).

I received the 2PAC from my cousin in the mail today. Using a USB 'Y' cable to supply sufficient power, a regular/standard USB multi-meter, & a 35W powered USB multi-meter (to add or decrease power). Along with several other things I tried to get it hashing, I used different versions of CGMiner. Here are some of the results:
