Hello, Frank I have the same identical problem with my ibook and Roland SCD70. I thought that it was related to the fact SCD70 has separate power supply, but now I suspect it's like Ivica pointed out (the charging circuit for the battery). BTW, are you able to run jackd with the UA-20? I get a message saying "your device either doesn't support one of the two sample format jack can use" or something similar...
