my NDSL wont detect the N5

[joestoes]

a rather strange problem i have is that my N5 refuses to be detected by my NDSL.
it simply goes to the screen that usualy comes up when nothing is inserted into the slot

and to make things stranger there is nothing wrong with the card, as i have tested it on my girlfriends NDSL and its works perfectly.

does anyone have any idea how to fix this problem?

thanks in advance
