FRM-KL26z USB host: ID pin connection

I would like to use FRDM-KL26 board as USB host. In the user guide (FRDMKL26ZUG), it says that 

 

- Jumper J9 shall be connected to get power out of FRDM board in USB host mode

- Resister R8 shall be shorted.

 

My question is, about shorting R8. I don't see that KL26 uC has a USB0_ID pin. In the FRDM-KL26 board, I don't see that ID pin (TO_USB_ID_TP) is being connected to an USB_ID pin in uC. So, is this even required?

 

If I connect a USB memory stick on the other side, which will never act as USB host, cant i just manually set USB peripheral in USB host mode?

 

Thanks!
