Hi All and Merry Christmas! Thanks for this good guide. I have a question about T410 NVS 3100 + Ricoh SD/MMC cardreader on El Capitan 10.11.6: Code (Text): <key>idProduct</key> <integer>59426</integer> <key>idVendor</key> <integer>4480</integer> I'm attaching my Info.plist from AppleUSBCardReader.kext with converted and replaced all vendor and dev_id strings. There is no SD reader in USB devices at all. So far no luck but maybe I am missing something? Thanks in advance!
