Why is this good? because there is nothing preventing you from using that usb stack to implement all sorts of faster/better/different usb protocols on maple! You could do fast isochronous pipes, for audio/video, or be an HID device (accelerometer mouse!) or whatever. The only catch is that the ide uses the virtual com port to pulse DTR/RTS and engage the auto-reset into bootloader mode when you hit program. This is just like how arduino does it. So if you strip out the virtual com port in favor of whatever hotness you come up with, youll need to either manually reset the board for programming or add some hooks to the IDE/your code to engage a reset. We'd love to see some advanced usb stuff happen on this platform! in the new library setup (libmaple + wirish, now in our github repo) the usb stack has been stripped out of the bootloader as a runtime library and is now statically compiled in to user sketches.

How straight-forward it is to write software for your computer that can access the USB port/virtual COM port at full and high speed USB data rates? Good question.

Do you have a particular application in mind? We certainly seem to get a lot of through put over the USB serial port though I can’t say i’ve calculated or tested the speed.
