I use an ADC212/50 with a USB adapter. I can't get ETS to work with the USB (although it does work with the parallel when available). I reported this problem 2 years ago (Problem 8657) and was told it was a problem with the USB driver and 'The problem has been documented in both our bug list and Problem report system.' Is this ever going to be fixed? I have tried the latest software, bit still have the problem.
