Boot pin:
Is the LPC1788 boot pin (P2_10) pulled high (to 3V3) on the G120 module or is it floating? If floating is it recommended that this pin be pulled high externally so the MCU doesn’t accidentally enter boot mode at power up?
USB Host pins:
Can the USB Host pins be used as GPIO if USB Host is not used?
USB VBUS pin (P1_30):
The LPC1788 datasheet indicates that P1_30 is the USB VBUS pin. How should this pin be connected to use USB?

There is internal resistor but it is better to add a pull up resistor on your end. This applies LDR0, LDR1 and MOD (It is easier to forget what the datasheet says as oyu are working with G120 not LPC788)

If brochure do not show the pin as GPIO, for example P4_44 then the pin is not available as GPIO. So the answer is no.

There is no “VBUS” pin on G120. If you need this then you can use any GPIO.
