But the maximum length is when it fails on you. There is no getting around the fact that one device may get 15 feet and the next fails at 3 feet. This is why folk end up with USB extenders.

Hi just a general question.
I want to get a longer USB cable like 15 feet. I looked it up on Wikipedia and it said a single cable s/b max of x feet but you can put like 5 together for 5x. Why is it ok to add more when there is a max distance on 1?
