Thanks! That got me thinking... I've got an Asus PC701SD sitting in my
backpack. I use it during my commute (by bus) every day. So, I plugged the
Microchip PIC32 USB Starter Board USB cable in to it. When I plugged it
in, a new directory showed up in /dev named usb. If I then do cat
/dev/usb/tts/ttyACM0 and hit SW1 on the Microchip board, I get the Hello
message from the board. That's pretty neat!
