LPC54608 DUAL USB and Device Mode question

LPC54608 USB question's (2).

 

1st USB question:

Can i have both HS Device and a HS Controller stacks running. I think the documentation states it supports both

running ? Can anyone confirm ?

 

I have single instances of Device or Controller demo's that run - both not both.

I have a design that requires both. Is there any Demo code that exercises both stacks running.

I suppose i could combine 2 separate Demo's and try it.

 

2nd USB question : For USB Device mode i need to implement the internal FS DP pullup.

How is this done ? 

I have tried enabling USB_DEVICE_CONFIG_REMOTE_WAKEUP - thinking this would assert the D+ pullup for host attachment. I desparately need the D+ signalling for device attachment as the host doesn't assert VBUS.

Please advise.

 

I'm using the OM13095 devel kit.
