Don't forget, there is a limit on how far USB can go. According to USB.org:
"USB specification limits the length of a cable between full speed devices to 5 meters (a little under 16 feet 5 inches). For a low speed device the limit is 3 meters (9 feet 10 inches)."

additionally, I did not know this and am glad I found out(even though I'll probably never encounter a problem like this)
" Q6: You mean I can't make a direct cable connection like a null modem?
A6: Correct. In fact, if you try this with an illegal A to A USB cable, you'll short the two PCs' power supplies together, possibly destroying one or both machines or causing a fire hazard."

That's a good thing to know - my cables are not totaling 5 meters, though, and I'm not doing A to A.
