why does plugging into a new USB port often solve USB problems?

I have 4 USB ports on the front of my computer and 6 in the back.

I suspect you are having power problems. With that many USB devices, some hubs can be overloaded and won't enumerate correctly. Moving to another port probably moves it to another hub which has sufficient power. The solution I have found when I've had these problems is to go get a powered external hub and plug into that. That has solved my enumeration problems every time so far.
