We are working hard on Linux version software. And hope to release it some time in next week.
We have a Linux version software now actually. It works in most case when do a single device mining. It has some issues on multiple device mining, especially on beaglebone black board. Because a issue in USB to serial driver, Only 5 devices can mine together on beaglebone black board. The good news is we have resolved this issue yesterday. We changed the communication API from COM to pure USB api. This change requires a cgminer upgrade and code merge. It takes time. The latest development progress: Today, we have confirmed that on beaglebone, more than 64 devices can mine overnight stably.

In summary, we will release a cgminer in next week. It is based on cgminer 3.7. Please stay in tune!
