They have a new beta 10.11.2 where a requested area of focus is USB.
I have my own problems with USB and El Capitan - see my own thread. For the moment I have given up and am using airplay.
It's really frustrating. I've tried everything I can think of, reinstalled Yosemite, reset pram and smc, changed USB cables, but it still happens. There's no way to repeat it reliably--it just happens out of the blue.
