In a spare computer I built, I put in a random card reader I had laying around (Product ID 0x9360, vendor ID 0x058f (Alcor Micro, Corp.)), it was a USB card reader so I added this kext, set idProduct to 37728, set idVendor to 1423, added it to EFI/OC/Kexts and my config.plist, however System Information still says "This computer doesn't contain any Apple Internal Memory Card Readers.". I'm running macOS 10.12.6 Sierra (16G2136).
