Steps to get your adapter working if you just upgraded to Mac OS 10.11 El Capitan.

Reboot. As soon as the screen goes black, hold down 'Command' and 'R' until you see a black screen with an Apple logo and a white progress bar. Let go, and wait for your computer to boot into recovery mode.
From the top bar, select 'Utilities' and then 'Terminal'
In the terminal, run csrutil disable.
From the top bar, select '', then 'Restart'
When you boot back up, you'll have a working adapter!
Definitely take a read down below to see what's changed in El Capitan, and if disabling SIP makes sense for your setup.

Steps to get your adapter working if you've never used the adapter before in Mac OS 10.11 El Capitan.

Unplug your USB adapter, and reboot and give yourself a clean slate.

Once you're booted back up, download and install the drivers from the CD, kindly uploaded by this fine human being.
Reboot.
Open your terminal, and run sudo kextload /System/Library/Extensions/USBCDCEthernet.kext
Reboot.
Plug in your USB Adapter, with a live ethernet cable.
Open System Preferences, and go to the Network Pane.

You're all set! Your adapter works!
Apologize to the people you care about for the things you've said over the past few hours. They won't understand, but they will forgive you.

What's going on. (Yosemite Version).

The old drivers still work, no problem, but are being blocked in Yosemite because they aren't 'signed' properly, since they weren't re-issued for Yosemite. As 'unsigned' drivers, Mac OS refuses to load them, saying they constitute a security hazard.

What step 5 does is instructs your computer to set itself to 'developer mode', which allows you to load unsigned kexts. This is a mild security risk, but it should be fine for most people. If you're in doubt, please make the decision that makes the most sense for your security concerns. You might be better off just buying legit Apple hardware so you don't have to disable the security. That's your call.

If you ever do go legit and want to undo it, just run sudo nvram boot-args='kext-dev-mode=0, and things will be back where you left them.

What's going on. (El Capitan Version).

In short, it's the same scenario as Yosemite, just stricter. Apple has a new security mode, called 'System Integrity Protection' (SIP) that prevents anyone - even you with your password - from modifying system files.

The old drivers still work, no problem, but are being blocked in El Capitan because they aren't 'signed' properly, since they weren't re-issued for El Capitan. As 'unsigned' drivers, Mac OS refuses to load them, saying they constitute a security hazard.

The csrutil disable step turns off SIP for your entire system, which allows you to load and use the drivers. This also disables malware protection for your machine, and given that we've started to see genuine malware for OS X in the wild, it's a slightly larger security risk than it was in Yosemite.

If you're in doubt, please make the decision that makes the most sense for your security concerns. You might be better off just buying legit Apple hardware so you don't have to disable the security. That's your call.

If you ever do go legit and want to undo it, just reboot into recovery mode and run csrutil enable, and things will be back where you left them.

Anyhow, after hours of searching and pulling out my own hair, I thought it'd be worth sharing the solution! Enjoy!

psst. Yeah, you, with the working ethernet adapter. :)

It's really, really good. Thanks!-Steven
