[RWP] Questions about long USB cables and keyboards

[Patrick Perdue]

If you have to run your keyboard in such a situation, I'd definitely 
avoid USB. I had problems even at 16 feet with those active USB cable 
things, though I had better success with some chip sets than others. 
Absolutely no good with Via and Nvidia chip sets, slightly better with 
Intel.

I have a set of 25 foot midi cables, and I've seen 50, so I'm sure 
something in the middle exists.
