I have an application where it would be useful to provide some external data to a program via the USB mouse or keyboard.
The Teensy USB Development Board would be ideal, since it's small and has direct USB support. Unfortunately, it would require a USB drive, and I would prefer a direct plug-in, like a thumb drive.
Given that the Teensy has the USB support built in, how difficult would it be to modify the board so that there's an edge card connection (terminology?) such that the unit can be directly attached to a computer's USB port?
Can standard layout tools and board fab services make such a board? Are there any routing specs available that can be dropped in to an existing board design?
Alternatively, are there any existing designs that might already include the USB edge connection?
