Hi Juan,
Thanks for the reply! I started with the config used for the ubuntu 
system running on my system and ran make oldconfig. Currently under USB 
support I have the following included:


Support for Host-side USB
    USB verbose debug messages
    USB announce new devices
   *** Miscellaneous USB options ***
	    USB device filesystem (DEPRECATED)
       USB Monitor

*** USB Host Controller Drivers ***
	xHCI HCD (USB 3.0) support (EXPERIMENTAL)
	EHCI HCD (USB 2.0) support
	  Root Hub Transaction Translators
	  Improved Transaction Translator scheduling
	OXU210HP HCD support
	ISP 1760 HCD support
	OHCI HCD support
	UHCI HCD (most Intel and VIA) support

	*** USB Device Class drivers ***
	USB Printer support
	USB Mass Storage support
	The shared table of common (or usual) storage devices


Should I possibly not include some of this?

Martins
