Hi
I want to connect two modules to Arduino DUE via SPI communication.
One module SD card and one module USB host (ch376s) .
I connect as shown below but they don't work.

Yes, i want to copy the information from usb to sd.
The data is too large and I can't store it in Arduino and disconnect the usb module.
