Title: GekkoScience 2Pac & failed usb_init Post by: johannesfritz on October 26, 2017, 04:32:41 AM Hello Ladies and Gentlemen,
so I got that 2Pac thumb ASIC miner and tried to set it up. I use the special cgminer build by VH. I learned how to enter the correct stratum/pool address and I installed WinUSB with Zadiq, which works correctly. The device is not listed as a COM device, but as a USB device. I run the .exe as an administrator. My batch file is in a folder called cgmine and that's where the .exe is located, too. The batch file is called "start mining.bat.txt" and it contains the following: "Start /D "C:\cgmine" cgminer.exe -o stratum+tcp://stratum.slushpool.com:3333 -u sohnes.worker1 -p anything" . The device is listed in cgminer, but not accessible, I always get "failed usb_init". [EDIT] I deleted the .txt file extension, now it's only .bat, but that did not change anything. As you can see, I tried to give you as many details as possible. If you need any more info, feel free to tell me. Thanks in advance for any advice whatsoever. :) Title: Re: GekkoScience 2Pac & failed usb_init Post by: veeref on October 28, 2017, 02:14:51 AM I had the same issue a couple of days ago after an overnight failure. I rebooted the machine, inserted the 2Pac, ran Zadiq as Administrator and had it reinstall the driver. Upon completion I unplugged the stick, replugged it, and ran cgminer. It detected and initialised it and began hashing.

failed usb_init Waiting for USB hotplug devices or press q to quit Need to specify at least one pool server (Which I did afterwards, but still failed usb_init). Now, when go to USB options and want to detect/hotplug devices, it asks me for a number. Which would be a correct range of values to enter? Or does this not have anything to do with my present problem? Title: Re: GekkoScience 2Pac & failed usb_init Post by: johannesfritz on October 29, 2017, 07:52:35 AM btw it the device shows up when I check the list of devices.
[EDIT] I also found the "write config" option. Obviously I had none before, so I tried it. Cgminer then generated a config, but it was empty, of course resulting in an error. Might this have to do with the prob? Title: Re: GekkoScience 2Pac & failed usb_init Post by: NotFuzzyWarm on October 29, 2017, 04:29:23 PM Folks, you DO know that there is an official 2PAC support thread (https://bitcointalk.org/index.php?topic=1764803.0)right? All questions like this have been asked and answered numerous time there already.
Try using SEARCH perhaps? Title: Re: GekkoScience 2Pac & failed usb_init Post by: johannesfritz on October 29, 2017, 09:40:44 PM Well, thanks.
