I have a Anker 7 port USB 3 hub connected to my iMac. After the latest OS 10.11.3 update it has completely stopped working.
Thinking it's got a 95% chance of being related to this update, rather than just a fluke of timing. Has anyone else experienced a similar problem with this update? Is there a fix for the problem? Thanks!
iMac, OS X El Capitan (10.11.3), 27" 3T Fusion drive
Did you download and install the firmware updates available from Anker to see if one might be applicable to El Capitan?
Yes I did. There appears to be no updates available for this product.
Then, you might ask Anker if they plan to release a firmware update for El Capitan. They had a 7-8 month head start with Beta software for El Capitan, so they can't claim that they did not know that it was coming.
I had this problem as well, and eventually stumbled into a fix. The Anker hub worked with Windows, didn't work with any Mac with OS X El Capitan recently installed on it, and when handed to an independent electrical engineer, everything internally looked fine.
It involves resetting the PROM and SMC. On my MacBook Pro for instance it involved holding down the four-chord Command-Option-P-R during boot and keeping it down for at least three chimes. Then I powered off the Mac again, and then booted with Shift-Command-Option-POWERBUTTON. The Mac took a moment more to boot, but then the Anker hub worked like it used to (which was excellent, by the way).
I'm sad to report that as of 10.11.4, the problem resurfaced and that the above fix no longer works.
It appears as if the Hackintosh community has figured out what's going on -- read the text at https://github.com/RehabMan/OS-X-USB-Inject-All
