USB Serial Adaptor Schematic

I just found an interesting site with schematics for RS232 to usb converter cable(keyspan). Amongst other things, pinout. I was actually looking for something to assist me with one of my usb stick soldering projects. I guess I'll have to keep looking. This is pretty interesting stuff though and I couldn't refrain myself from posting it here. I hope you enjoy it as I have. It is no doubt useful to someone. Thanks dudes at pinouts.ru
