USB not recognizing after install

Has anyone else had issues of USB devices not recognizing after the installation of El Capitan? If so, have you found a fix for the situation?


My issues have been specific to a Neat desktop scanner and a Fitbit sync dongle. Both have been uninstalled and reinstalled but do not recognize in the updated OS.

I have run into a similar problem with Canon MX860 after El Capitan install. I am no longer able to use the scanner.


When I attempt to reconfigure, the Canon IJ Network tool does not see the printer connected via USB, although I am able to print to the MX860

Update: FIXED.


Others may not be so lucky with this but I was able to find a fix.


Luckily I have a dual boot on my Mac, so I rebooted into my old OSX 10.9. Using the old config I was able to access the MX860 configuration and updating settings. I then tried a PRAM reset (power down, press power on and immediately hold Option, Command (⌘), P, and R – don't let go of the keys until you hear the boot chime twice).


When I booted back into El Capitan all is now working fine with the MX860 (printer and scanner).


Note it is possible that the PRAM reset alone solved the problem, it may not have been necessary to boot back into the old OS but since it is now working I have no way to confirm that.


Hope this helps someone!

My situation was an unrecognized photo SD card on a mid-2011 iMac 27. Unrecognized and could not be found using disc utility,

The computer had been sleeping before I woke it up and inserted the SD card.

A Restart solved the problem.

I zapped my PRAM after reading your post, Scott, and it made no difference. I see two immediate issues that I never had pre-Capitan:


my iPhone stops getting charged when the system sleeps. I'm used to syncing my iPhone every night, and charging it. I'm disappointed to see it start at 100% charge and see 70% by morning (no apps running).


my FitBit dongle needs to be removed and reinserted to make connectivity each time after the iMac sleeps w/El Capitan, not on prior O/Ss.
