Sorry, I thought that I send answer yesterday but it's look like I prepared the answer but 
I  forgot to send. 

In /drivers/usb/Kconfig we have: 

config USB
	tristate "Support for Host-side USB"
	depends on USB_ARCH_HAS_HCD
	select USB_COMMON

and in /drivers/usb/gadget/Kconfig we have:

menuconfig USB_GADGET
	tristate "USB Gadget Support"
	select USB_COMMON

I think that it should cover all cases. 

Am I right ?

Pawel
