I have finally consolidated my instructions for building a USB Chordite
prototype into a zipped kit anyone can download at chordite.com.

For some reason the new firmware within it, series6-Chordite.hex, which is also
available in the files section of this Yahoo group, fixes what I've been calling
the contact bounce problem in the Omron SS-01GL13-F switches. My best guess is
that this has something to do with changes in Atmel's USB code. Whatever, I
must now retract the bad things I've been saying about those switches, provided
you use the new code.
