To those with the 2016 MacBook, you may want to hold off installing the latest El Capitan Beta if you need to access USB drives. I noticed that any drives requiring USB 3.0 power do not seem to mount with the new beta. If I revert to 10.11.4 the drives mount with no issue. Kudos to the Genius Bar rep who spend 30 minutes with my MacBook trying various tests and then encouraged me to try downgrading before sending it back (saved me the hassle of being without the MacBook for a few days).

FYI, this is still present in the current beta 4.

Must be your drive. Works fine for me.
Not my drive. I tried it with 2 different flash drives and a USB Ethernet adapter. None of them worked. All 3 work fine in 10.11.4 and for that matter in 10.11.5 on my old MacBook. Apple replied to me in less than 24 hours when they normally take weeks. Maybe it's my MacBook. I sent Apple my System Diagnosis files. I'll keep you posted.

my usb drives are working fine here in 10.11.5pb3 and now pb4...
Are you using a 2016 MacBook?

For me everything was fine in 10.11.4. I even migrated from my 2015 using Target Disk Mode over a USB 3.1 cable. But as soon as it downloaded and installed the beta the USB port stopped working correctly. If I reinstall 10.11.4 it works. Perhaps it is a software incompatibility with something I'm using, but I have a fairly simple setup.

Oh sorry, I was under the impression you were on a retina MacBook Pro. The R threw me off - I too am on an retina MacBook Pro not a retina MacBook.

Same here : 2016 retina macbook, USB 3 drives work perfectly on 10.11.4 and not on 10.11.5 beta.
USB 2 drives have no problem on either version of El Capitan.

It is my impression that USB-c peripherials can be hit and miss at the moment. Is it possible to test with another drive OP?
These aren't USB-C peripherals. We are noticing this issue plugging in USB-A 3.0 peripherals into App,e's adapters with the latest build. USB 2.0 devices seem to work. That suggests to me that the beta software is interfering with the voltage needed to mount USB 3.0 devices.

Here's what happens when i plug my usb 3 SSD on my macbook. I unfortunately couldn't find any info that i could understand :/
