I just made a short investigation about it at Intel site and I am still surprised how easy it seems to be.
This is the link to
Intel PXA270 CPU.
At
Technical Documents section we have the doc:
Intel® PXA27x Processor Developer's Kit Schematics
At page 9 (Daughter card secondary connector) is shown:
CPU pins 52 (USBH_PEN0), 54(USBH_PWR0), 58(USBH_P0) and 60(USBH_N0) witch are the CPU USB HOST 0.
CPU pins 40 (USBH_PEN1),42(USBH_PWR1), 46(USBH_P1) and 48(USBH_N1) witch are the CPU USB HOST 1.
Page 29 shows an example of motherboard where the USB circuit driver is completed:
It is labelled as
USB HOST 0 and
USB HOST 1 (second one is tagged as "do not populate").
See how it just add a couple of integrate circuirs to drive signals and take them directly to a standard USB connector.
It would be nice to know if X51V motherboard populates USB HOST circuit driver or at lest if it has the room left. But still without anything of that:
It seems peace of cake!
I am not going to do anything about that yet because I still have a couple of moths of warranty left. But maybe there is someone interested about it.
