Reminds me of when I couldn't charge the my battery the other day no matter what OS. Had to do an EC reset by cutting off all power from the machine and holding down the power button for like 20-30 seconds. Happened like 2-3 times now.Yes but you also need the boot-arg.
Keep in mind that if some of you can't seem to make the Card Reader work at all on macOS, there are some cases where it may go into a bad state, an EC reset could fix it or sometimes for me just booting Linux/Windows and plugging an SD Card in will fix it, then either reboot or shutdown and boot into macOS.
I just recently had a case like that where it wouldn't work anymore at all, the driver appears loaded just fine but it won't mount or detect any SD Card at all.
What i did is: i booted into Linux, plugged an SD Card, it loaded fine, Shut Down the system, boot it into macOS and as soon as i plugged the SD Card, the icon appeared.
