As you'll see in these topics that firmware on MCU and device driver/ host app on PC are more tightly bound in USB development than RS232 age. It makes USB development difficult.

I agree with that KEIL provides just the compilers and libraries for MCU, they don't provide total solution throughout USB development. I think it's fair attitude for KEIL, they should focus on what they derive from. Then, I hope this forum can help members to guide them on the rest of USB development.
