Some of the kids at my son's school use a device called an
AlphaSmart to upload their homework and answers to tests
into the teacher's computer.
This device is a keyboard with a 10x40char LCD display and
editor and enough memory to store a few pages of ascii text
files. It appears as a USB keyboard to the host computer.
The kid plugs in the USB cable, fires up the editor on the
host computer and hits "send" on the device, whereupon text
starts filling up the screen on the host computer. You can
also just use the device as a USB keyboard.
Since these devices are about $400, they're more expensive
than a used laptop. Is it possible to use a laptop as a USB
keyboard? I assume I'd need a USB bridge cable as the
transport level. However at some higher level (don't know
what it's called) the laptop thinks it's managing a USB host
controller, rather than being a USB keyboard.
Is it possible to have the laptop function as a USB
keyboard?
Thanks Joe
