PRESENTATION

Eric Wilhelm -- Stupid USB Keyboard Tricks: Reading magstripes, barcodes, 10-key pads, and keyboards with libusb.

An overview of libusb, how usb keyboards (and keyboard-like devices) are handled by Linux and X, and how they can be disconnected from the main input driver for use and abuse by user-space code.

This technology has useful applications such as connecting USB credit-card and barcode readers to point-of-sale software independently from the keyboard focus or keymap. It also allows silly things like multi-player text editors or a 105-command program launcher. Or you could just use it to change songs in xmms.

Code will shown in small doses of Perl and C. Hands-on demonstrations will be included as time allows.

Caution: presentation may result in a desire to attach one or more additional devices to your computer.
