Customize Disk on Key (implement USB interface)

This project is to create a customize disk on key. All basic disk on key functionality should be implemented + few customizations. You should implement USB interface operating as a default USB MIDI device class. When the microcontroller is plugged in to a PC or Mac, the example will mean it gets recognized as a default MIDI device (recognized by the default MIDI drivers supplied with the OS), and allow the microcontroller to send and receive MIDI messages. Once the device is plugged in and recognize it will need to run an executable file ([login to view URL]). In the end of the day the device will store my exe file (+few more files) and run it once it is connected to the USB interface of the PC (with no human intervention) and when the computer is locked (not shutdown, only lock). You should include one page that describe the solution and the requirements in order to make sure we are on the same page. you can choose the board and the microcontroller (+memory) you want. you will need to purchase your own the board, so you may want to cover your cost as part of the bid). The code delivered should show the core USB MIDI functionality and enable simple further application development of something wanting to utilize USB MIDI. The example should not include any third-party USB stack code. Deliverables are full source with build, execute instructions and the board itself of course  Anything that isn't already open source licensed becomes my property.
