A while ago, I tried to fire up my old Dmx Fire6 usb soundcard to do some recording. It didn't work. There appears to be some blue LEDs shining, but appart from them it does nothing, and neither my PC nor my mac can find when connected through the usb port. It's just been lying in a cupboard the last couple of years. I've disassembled the unit to look for any signs of fried components, but everthing looks clean. Any suggestions for where to go from here? I guess I could always just gut it for parts, but it would be nice to actually repair it my self.
