USB Host for microcontrollers

It isn't a problem to create an uC-based device as an USB peripherial nowadays - there are a lot of chips with USB device capability, from FTDI to some PIC/USB, or OBDEV's USB software controller. But what to do if you need connect some USB peripherial to your device?
