Q: Unable to detect CF card in El Capitan
Hej! I just installed El Capitan yesterday. Today I was trying to mount a CF card using a Lexar card reader but it did not show up in Finder. This is how I normally import my photos, however, this time it did not work. I tried the reader + card in an older machine which has not been upgraded and it worked there. I checked the USB port on the first machine by plugging in a harddisk and it also worked. So pretty sure it has to do with the upgrade to El Capitan.
Has anyone else had CF card mounting issues with El Capitan?
MacBook Pro with Retina display, OS X El Capitan (10.11), Lexar CF card reader

I contacted the Lexar online chat support: http://www.lexar.com/contact-us
They recommended that I use my old machine that still was able to see the card reader and upgrade the firmware on the reader to get UDMA7 support. You can get the download from their server:
After following the instructions in the zip file and upgrading the firmware the reader worked again on my new mac with El Capitan.
