[simpits-tech] More on USB

[Matt Bailey]

Just ran across this article while researching USB interference via
inductive loads (relays, motors, etc), very interesting:

http://www.controlanything.com/i.htm

Basically, they are saying to avoid USB for ANYTHING that involves any
sort of inductive load. I knew USB was finicky, but I had no idea there
is exactly ZERO ERROR CHECKING/HANDLING for the USB spec! No wonder we
have so much grief with USB-based devices!

Amusingly, they recommend going to good ol' RS-232 as one option for
controlling inductive loads.
