Why would it matter if his MD recorder has USB 2.0 compliance? He wouldn't be able to upload digitally through the USB unless he is using one of the new (and very expensive) Hi-MD formats. And even then, it would work up until he decided to get an external A/D (if that ever happens). Then the upload will not work; it is SCMS prohibited.
Better off just dumping the MD all together and going with a JB3 instead. And this is coming from the guy that still runs his original MD recorder next to his new(er) DAT, just for old times sake!
