I have Mint Linux installed on my computer and I just started playing around with the gridseed ASIC device. I have everything setup fine but I keep getting the end result that I didn't want. I installed cpuminer in this manner

I downloaded the gridseed version of it, then I downloaded all the necessary dependencies and ran these commands in the directory containing the cpuminer program source files.

The program compiled and installed fine, the minerd command is available and I can use it. This is where I started running into problems. I ran the following command

The program starts to run and I leave it alone for 15 minutes. When I returned I see that I can only see yellow lines of output. I am supposed to be seeing green lines of output which would indicate to me that it is hashing away and is mining coins. Instead there are no green lines showing in the terminal and I am assuming this means that it hasn't been doing anything. to top it off the site of the pool shows my worker doesn't have a hashrate next to it. What am I doing wrong here. I know for sure it isn't the device since I got this all working in windows 7 earlier. I want it to work in Linux but it doesn't seem to be working for me in Mint. Is there a different Linux distro that you would reccomend or is Mint good enough?
