Connecting minisd io pins directly to the usb io pins?

to me, that definitely looks like the way to go, but i am no hardware guy.
you could get two of these, break one open and have a look if there's some kind of chip inside or just wiring.

it seems there is no chip inside
my pal got one of those reader
i'll see tomorrow

hm? i thought the USB port of the N900 is not able to handle even this kind of USB devices?

edit: woops.. please ignore. haven't recognised that it is a N810 you are talking about.

Re: Connecting minisd io pins directly to the usb io pins?
 

it is a solution ONLY mechanical. SD card signals are incompatible with usb without controller.
if you bought usb to sd reader ( have an controller inside !! ) you need also this adapter ( standard usb a female to microusb a male ) for your N810
