LPC2388 - Can I use a GPIO instead of VBUS to detect the presence of a USB host?

Hello,


I designed a board, based on the LPC2388, with an USB device interface.



The VBUS (pin P1.30) is used as an ADC and not as a VBUS detector.



QUESTION 1
Can I use a GPIO pin to detect the status of the VBUS?



QUESTION 2
Which software corrections I have to do to Keil HID demo program?



Thanks,
Enrico Migliore
