Just to let you guys I'm still fiddling with it but so far the Raspberry Pi software needs more work. I can't get the LL to connect to anything through it but if I just connect the LL directly to my PC ( although I'm using a hub for it ) with the USB cable, like you would a jalapeno, it works just fine. So far it's chugging along without any problems and aside from the firmware not working everything is in order and of good quality. I am using the CGminer version that is available at the Hashra site and I've been solo mining to test it out but will go to a pool next in a few hours. I also appreciate the manufacturer doing "the paperclip thing" in advance with the power switch but make sure the factory people press it in all the way. It kept powering down on me until I realized that it was not pressed in all the way in.
The error with the firmware has to do with the "socket can't connect" issue I have seen online already. I also get different messages like the pool had no credentials and the GUI will hang indefinitely until I close and reopened the browser every time I save, restart, or reboot. Plus, it seems to hate Firefox. I could only get it to load once with it and the rest of the time I had to use IE to access the dashboard. So unless it's user error it needs fixing but I spent quite a few hours trying to get it to work. But in the end, so long as it hashes I could always use a third party dashboard in the meantime.
What are you using to power your Pi? Quite often lack of power to the Pi can give weird results. When I used the cable that came with it, the NIC would not power up. Just grab a micro usb phone charger that outputs at least 1A (1000mA) and that will be sufficient. Don't be concerned if the charger output's greater than 1A as the Pi will only draw what it needs. Voltage on the other hand is a different matter, micro USB phone chargers output 5v, just make sure if you decide to use any other power source that it is only 5v, and that the 5v is steady.
Also which miner do you have? As it appears from the support page that there is different firmware for the Lunar Lander and Lunar Launcher, so it's worth double checking that you are running the correct version by downloading the correct one from the support website and flashing it to a new SD card. Think you only need a 4Gb card, but I generally use 8gb ones with my Pi's.
