SD card failed with SME

Hello, I have a problem with connecting sd card with SmartEverything. I am using SD.h library and it writes me

if (!SD.begin(4)) {
    SerialUSB.println("initialization failed!");

any suggestions? Sme has same Mosi,Miso,SLK pinouts.

any suggestions?

Pretty dumb not to post a link to whatever the SmartAnything is. I suggest that you also post a link to the SD reader/writer you are using AND a schematic showing how you connected it.
