USB Host (HID-Keyboard) on LPC2362

Hello,
I want to make a USB-Host work on the LPC2362. Therefore, I found Sample Code for the LPC2388(in the MCB2300-folder, refer to www.keil.com/.../rlarm_usb_host_hid_kbd.htm) that provides a Host for a HID (Keyboard). I sligthly adapted it to the LPC2362: Pinsel for USB_D+1, USB_D-1 and USB_OVRCR1. I provided 5V-Power and adapted serial interface configuration. I also let USBPortSel at reset value (to select Port1).
But trying the Project in Hardware does not work. Do you know where I could start debugging? The function usbh_hid_status(0, 0) always returns zero to me.
I hope that Hardware is correct, since it only has 2 wires.
Is there other configuration, that I must adapt? I am not to sure what to do with clock settings, for example.
Thanks for any help!

Sincerly yours, Stefan
