SD card does not work if USB flash drive is not connected #112
My SD card slot on the LCD slot (mks mini12864) only works if I plug in a USB stick. Connecting SD without a USB stick, the display reports a media error. If I disable USB support in the firmware, the SD card works normally.
Hey guys,
Please am I doing something wrong? When I use:
define USB_FLASH_DRIVE_SUPPORT
define USE_OTG_USB_HOST
