I've accumulated a variety of USB cords from various purchased devices. MP3 players, external drives, PDAs, etc etc. Some have thick gauge wiring, some have thin. Some are straight, some have cylindrical pieces midway (looking like a snake that swallowed a mouse) that I presume do something.

I've long since lost track of which wire goes to which device. Does it matter?

Thanks

I would say no, but some here might know more.

The "swallowed mouse" is a ferrite bead. It stops high frequencies
exiting electronic devices which might interfere with other sensitive
devices such as TVs or radios. It rounds off the corners of digital
signals. Will it effect data? Probably not. Most of the time,
electronics is a trade off.

The wikipedia knows all:

I hope not because I interchange USB cables all the time. Never had a problem except one time using a cheap multi-tip USB adapter kit--The USB connection on my Harmony remote died and I was no longer able to update it with any USB cord. The remote was under warranty and Logitech replaced it. No way of knowing whether the fault was with the adapter or the remote, but I avoid using that adapter anymore.
