Dont know if this is on topic, I have 5xlancelots, But 2 of them are not recognized by the computer?

to cover the basics, I am using xp with bitminter client (yes I am a noob) I have swopped around all cables power adapters, Its the same two boards not being picked up, When I scan for all FPGA's on com ports the 2 in question have a different light cycle to the others, The 3 detected quickly show a orange and blue light together, The other two don't. (but all flash together at first)

I have no idea what the 6 push buttons do (have not pushed them) 4 on one side 2 on other.

Any suggestions?
