iMac (Retina 5K, 27-inch, Late 2015)
I've seen people post with the same issue and was wondering if anyone has found a fix for this issue.
The card reader starts at boot up, but eventually stops recognizing cards when they're inserted until you reboot.
Thanks!

I had the same issue but started to work after I updated to the next OS revision.

I had the same issue. It was solved when I brought it to the Apple store and they reloaded the firmware.
That stands for milliamp or current draw although an SD card would draw very little current.
milli Amperes...
Many times it's due to drawing too many mA on the USB Bus.
Could you please explain what is mA?
