CR-10S does not see the SD card

Very frustratingly my CR-10S does not see the SD card. SD card is good because my PC reads it and I have tried 2 different cards. I’ve tried in the past to connect it to my computer with the USB cable but the computer will not see the printer. So I have a printer that works well enough and now no way of getting a model into it. The printer is about 15 years old still with the original controller. I am wondering what my options are, can anyone point me in the direction of getting a new (or better) controller, or should I call it quits and scrap the printer?

Any help would be appreciated.

I have the same problem with CR-10 V2 and V2.5.2 Main board . I found that the SD card supplied by 3.3V but the signals are 5V which is wrong but I succeed to communicate by USB COM3 with diver CH340
