Dear Log,

So is there an actually good reason for the fact that I can't plug a USB cable into my laptop and into my PC and have them both magically notice the other's existence, and do something useful like allow file-swapping?

    • Remember, the S is for "serial." When you want to plug two computers together with a serial port, you can't just use a serial cable, you need a null-modem cable. In the same way, I think you need a crossover USB cable to handle this. Not to mention some special software. (I hope you're using an open OS, or you're probably out of luck! :) )

      I've heard that people have burned their USB controllers trying this. Wouldn't know personally; the only USB controller I ever burned was hooked up to sonars and a
