Is the FlexBay Drive USB 10 pin header connection the same as a IEEE1394 USB 10 pin header?
I would like to install a 3.5 internal Multi Card Reader In my 9150/XPS400.
...Just had to look around & found the right postby ChesterMark on another thread.

As promised, here's what I got from Dell Tech Support:-
It was a rather vague .bmp diagram with no annotation. Turning into a non-graphic gives ...
Pin 01 - Port 2 Power +5v (Red)
Pin 02 - Port 1 Power +5v (Red)
Pin 03 - Port 2 Data Negative D- (White)
Pin 04 - Port 1 Data Negative D- (White)
Pin 05 - Port 2 Data Positive D+ (Green)
Pin 06 - Port 1 Data Positive D+ (Green)
Pin 07 - Port 2 GND (Black)
Pin 08 - Port 1 GND (Black)
Pin 09 - absent
Pin 10 - present but they didn't label it! I assume it's the extra Shield/Ground.
The header on the mobo is a 5 row x 2 column header and is labelled on the circuit board with Pin 1 being top left, Pin 2 top right, Pin 9 bottom left & Pin 10 bottom right.
The above pin-outs therefore mean that the USB2 connections take the left hand column of pins, and those for USB1 the right hand column.
This is the standard Intel USB header layout, except on the actual header Pin 9 is ACTUALLY physically present.
The pins are spaced at an unusual pitch which took a lot of research to source. They are at 2.0mm rather than the more usual 2.54mm.
When I queried Dell Tech Support about the fact that their diagram showed Pin 9 missing while my mobo definitely had a Pin 9, I got nowhere. I even sent them photos of the header!
WRT the BIOS, and m888's question: yep, that's what I thought. Dell leave it disabled unless they fit a device when they initially build the machine at the factory. If I get anywhere with this as a solution, I'll post an update. I'm sure the User Manual entry is a typo
WRT eBuyer's reviews: yep, I read them too - that's where I got the Mitsumi in the first place
As before PLEASE post if you're the wizard who's solved this problem!!!
Cheers,
