...until now I didn't know what to expect - just because of that weeks of silence on this page after first great article. I'm looking forward for new articles.
And one suggestion: should it be possible to port PC USB sotware from first article to Visual C++ (or just to sketch some helpful piece of code to talk to USB device)? I'm programmning MCU's for a few years, but I have very little experience on PC programming, just a few programs in VC++; and it's always better (for beginner especially) to start with something functional than to start from zero point.
