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,
CJ

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).

A little background info for more detail.. CJ is my cousin. I was recently in Indianapolis to take care of my ill Grandfather who was on hospice. I am very experienced with these (and the original COMPACS) for those who don't know me.

While I was there, I ordered two 2PAC's from sidehack while there & set everything up for him. We ordered 2 USB Y splitter cables, used a decent powered USB hub, had a 120mm box fan that provided excessive cooling, & were running both sticks at 200MHz with no problems for several weeks.

A few weeks later, my Grandfather passed & I returned home. I left 1 of the 2PACS with my cousin (and it was running fine before I left), & took the other with me. After a few days of being home, the stick began acting up as he described. I spent over an hour on the phone with him in an attempt to help get it running, but nothing worked. Told him to order a USB multimeter so we could have a more accurate reading of the electrical specs than his old circuit tester provided us with while I was there setting them up.

He shipped the stick to me earlier today (just outside Philadelphia, PA), & I will attempt to get it working. I will update once I receive the stick, but wanted to rule out the possibility of user error (even though my cousin is in IT & a whiz with computers) before reaching out to sidehack for warranty repair.

Thanks for all of the help in the meantime (my cousin was having some trouble believing me when telling him about how willing this community is to help one another, so it's great he got to see for himself)! Wink

2017 JUNE 12 UPDATE:
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:
