enable two usb host on s3c2416 processor

Hi, 

I am using ARM9 based s3c2416 processor. The SoC has one USB host 
controller and one USB host/device controller. What are the 
register settings that should be done to enable both USB 
interfaces as USB host controller. ? There is a register PHYCTRL
 with address 0x4C00_0080. Its bit[0] says something on USB host
 mode and USB device mode. Is it this register which I should 
work on or any more register configurations are required ? 

Thank You
