Just a comment from my playing with LIDE30.  Try different USB cables, assuming we are not talking about PP scanners?

I found out getting a short cable, like 1foot (molex brand) with conductor writing on plastic as 22awg/C2 gives better performance with no noise yet but I've still to play.  Just in case this is actually a power issue, not that I want to suggest there is nothing else wrong.  The cables I got off ebay at long lengths didn't work at all.  Unfortunately the LIDE30 does not have an external power option, perhaps others in their ranges do.
