I’m able to read and write to my SD card both when it’s inserted in the machine and my computer (Mac), respectively. But when connecting a USB cable between the machine and computer and trying to enter “USB MSC Mode” the following occurs:
My computer can’t recognize the machine as a USB device
When hitting “USB MSC Mode” a first time nothing happens, a second time it says “No SD card inserted”. I then have to reboot the machine to be able to read and write to the card again
I have re-formatted the card several times and been trying different cards (SanDisk, Samsung, …) and different cables with the same results.
