Sd card detection issue (no replies)

Hello all, I have some issues with sd card detection.
I'm using motherboard which has sd card slot, and the sd detect pin is defined in Firmware marlin 1.1.9.
The issue seems like sd card status doesn't update when the detect pin status changes. When I insert sd card before connecting with pc(repeiter host), PC can read SD card, but when I insert sd card after connecting with PC I cant check the sd card on the host.
How can I solve this problem? Please help me out. Thanks in advance:)
