Last night I started implementing V-USB, and as it turns out, it was much easier than expected. I soldered the remaining components required to get the USB connectivity running, and the device now enumerates as as USB HID device!

I have run into a couple of issues that require a RC3, but so far there's no reason why RC3 shouldn't end up being the final.

The DPRAM will be soldered as soon as I get some decent flux.
