Problems with sd card reader in a wrt54g ver.2

[Duff]

Hello,

i have put an sd card reader into my wrt54g ver.2

But i got this error message

mc Hardware init
mmc Card init
mmc Card init
mmc: error in mmc_card_init (1)
mmc: error in mmc_init (-1)

I used the following pins:

PIN 1 --> CS
PIN 2 --> DI
PIN 3 --> VSS
PIN 4 --> VDD
PIN 5 --> CLK
PIN 6 --> VSS2
PIN 7 --> DO

I also changed the PIN 5 (CLK) and PIN 7 (DO) but i got the same error message.

Here's what i have done

Thanks for any help!
I don't know what i can do.
