hardware side. The software side would need to be beefier, but I prefer to make all the complicated stuff done software side. hardware is hard to change when you find a boo-boo. Software updates are nice!
So once in, this chip will not need any USB specific drivers. You will not need to find the unit ID and map it to configure the device and send every signal like with a standard USB bus chip. This chip is awesome, and hence the price. Of course the price goes down when you buy over 100 of them... You want any?
