My USB powered, Edirol UA-1D Audiocapture device no longer works. (digital I/O with both coax and optical) I noticed it when trying to record from a minidisc Using Bias Peak 4.02. I tested it with just the OS and it doesn't even output anymore. I was using it in Mac OS 10.3.3 just before updating to OS 10.3.4 and that's when it died. I tried all combinations of plugging and unplugging the USB device. Still doesn't work.
