I'm trying to use Stepmania in Ubuntu because windows 7 won't recognize my dance pads. I couldn't get Stepmania 5.0 to play sound so I installed the previous version. Now the program only detects one of the pads. Ubuntu detects two seperate pads when I check. But Stepmania only sees the newer pad. Oh, if it matters these are two different models of Red Octane dance pads. One is slighly older than the other. Anyone have any advice on how to correct this problem?
