[Bug 1307674] Re: Broadcom BCM57765/57785 SDXC/MMC Card Reader doesn't work for Ultra High Speed SD cards

 

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.

Bug description:
  I have a Broadcom BCM57765/57785 SDXC/MMC Card Reader internally in my
  MacBook Pro Retina 13", and it does not work.

  WORKAROUND:
