Glad to hear it. It's unfortunate that we're stuck with all of the HID  
layers of abstraction just to make it easier to talk to USB devices on  
older versions of Windows (without a custom driver).

I probably should have mentioned this earlier, but Jan Axelson's "USB  
Complete" is a great desk reference, covering everything from high- 
level USB APIs down to the electrical signalling. And the USB and HID  
Class specifications are not nearly as inaccessible as you might  
imagine (the PDFs are easy to search).
