As soon as I went to Sierra from Mavericks using USB external devices, in my case it's been hubs external hdd's, my DSLR, printers, etc got totally borked. Mavericks, no problems.... well maybe the odd ext hdd disconnect... but everything worked. Now its all a s**t show.
I've managed a stable situation using DAW apps (Logic, etc) by having 2 bare drives for samples in a OWC USB dock, 2 audio plugin dongles in the usb ports of one of my monitors, a keyboard controller , 2 other midi controllers and my keyboard/mouse into a USB 2.0 hub and finally an audio interface.
If I try and connect ANYTHING else USB to this config, it either doesn't mount, won't boot/freeze/crash, or if it does boot, play havoc with my system and software applications.
I may get an external hdd, camera or printer to work only after I disconnect everything else and boot up for that situation.
Now before you say I'm having conflict with another device, some devices won't play nice or work even with just that one particular peripheral connected, besides, of course, a keyboard and mouse which is a must.
I've just had just a simple hub connected and it eff's up the machine. I can't even go back to Mavericks because the bloody 'Sierra-ized' computer won't let me boot from my clone...I just get a screen with gobbledygook written on it when it tries to boot.
I even tried removing it form its case and used it a bare drive, and still won't boot.
After I installed Sierra, I couldn't even Mac format new external drives I bought. I had to do some research and use my PC laptop windows disk manager, go into windows command terminal, then delete some 'diskpart1' crap. Only the I was able to format the disks to Mac on my mini.
NONE OF THESE THINGS HAPPENED WHEN I HAD MOUNTAIN LION OR MAVERICKS!
I've done PRAMS and SMC's.. useless
I looked into this and it seems this has been an issue with Apple not playing nice with the USB protocol since EL Capitan/Yosemite
