I'm running as root, so I doubt a permissions issue. Just for good measure, I did add my unprivileged account to the plugdev group and added the udev rules. Re-tested after a reboot...no change.

More testing...

Turns out I get differences from one attempt to the next, even with no change in configuration. This somewhat makes sense as was giving me TIMEOUT errors. As things stand now, I have about a 1 in 3 chance that any given attempt to run will work. If it fails, un-associating the Gekko and re-associating it to the VM has about a 50% chance to make it work again.

I'm going to chalk this up to timing sensitivity in the Gekko or the driver, combined with latency between the virtual machine and physical device. Hope it won't be an issue when I move to a Rpi instead of the VM.

Thanks for the help. I'm up and running at roughly 14 Gh/s at the moment.

I did install libusb, but apparently it was linked against a different version than was installed. Not sure why.

Updated status in debugging efforts:

I completely rebuilt the VM from scratch. It is a fresh Ubuntu 16.04 install.

I followed the build instructions from the first post exactly...with one exception. When came time to run autogen.sh, it errored complaining of a couple missing packages. I installed those and re-ran. All appeared successful. Attempting to run cgminer results in the following errors being repeated printed.


I have the Gekko attached to the VM in Vmware Fusion. I'm wondering if there is some incompatibility with using the gekko with a virtual machine. Has anyone successfully done this? If not, I'll just hold off until I get a Rpi and go straight to that solution.

Thanks

I just tried building the custom version from the first post on an ubuntu 16 VM. It errors out immediately, missing libusb-1.0.so.2.

Forgive me if this has already been answered. I've spent the last couple days searching with little luck.

I just purchased a GekkoScience 2Pac. It's up and running using cgminer (version 4.9.2 shipped with MacMiner). However, the hash rate seems to be relatively stuck around 500 Mh/s. It will peak higher, but not for long.


Right now I'm using this for a command:


I've attempted building the custom cgminer from https://github.com/wareck/cgminer-gekko on a linux VM, but had troubles getting it to recognize the Gekko 2Pac.

Is there a recommended setup to get a hash rate closer to advertised? I'm running it off a laptop for now, but will be moving to a powered hub and rpi setup soon.

Thanks for the help
