choose a port you're always going to plug it in (and nothing else) and stick to it. it must always be plugged in when the comp is switched on or the comp will see nothing on the port and the driver will be disassociated with it.

hope this helps
That shouldn't matter, I don't think?

I plug my DigiCam into a different USB port each time, and it works fine.

It'c alled Universal Serial Bus for a reason... It's supposed to be totally pervasive and ubiquitous. I don't think you should have to reload the drivers each time you change a socket... (since they all run off the same bus anyway, supposedly?)

EDIT: Each time you disconnect, are you stopping the driver correctly? You shouldn't just yank out USB cables willy nilly.
