DIY USB Hub anywhere to find?

Hi there!

My first posting here! :mrgreen:
Has anybody seen a page, where DIY USB Hubs are available? I wanna build some big USB Hub (about 16 Ports or something) myself. Its for some friend of mine.
Its also cool, if somebody just has some schematics about that.

Would be cool!

I noticed Maxim make a USB hub in a chip. Wasnt what I was looking for at the time, so I didnt pay much attention but I think thats what it was.
