You have understood correctly. The mentioned patch did not change anything, whether or not I engaged the workaround.
That said, to my eyes, the patch looks like it might be related. There are some mentions of broadcom quirks and UHS mode in there. But the bottom line is that I didn't experience any difference with the patch. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1307674 Title: Broadcom BCM57765/57785 SDXC/MMC Card Reader doesn't work for Ultra High Speed SD cards Status in “linux” package in Ubuntu: Triaged Bug description: I have a Broadcom BCM57765/57785 SDXC/MMC Card Reader internally in my MacBook Pro Retina 13", and it does not work.
