Having Problems with SD card and USB shield Host Compatibility

Hello,

when I use the sd card on the mega or the arduino uno it works. Everything is fine. However, when I use it in combination with the USB shield host it doesnt work. I know the usb shield host works because the LCD display works and the barcode reader works in it. It is not the sd card because the sd card works with the boards alone. It is only when I add the shield that there is a connection issue.

I get the error: Initialisation failed in the serial monitor. I tried writing it high but that didn't work.

Any ideas?

WIRING: CS = 10 (I already tried digital 4) VCC to 5v

MOSI to 11 MISO to 12 and SCk to 13

board, wiring?

Uno?

Host Shield uses pin 10 as CS. use pin 4 for SD module. what SD module. some cheap SD modules disturb the SPI bus

I have a cheap arduino (not the real one) and also the shield :/.
