[Help] Displaylink not showing any life

[D4rryl]

Hello,

I recently bought a USB 3.0 to 4K Adapter (USB32HD4K) and installed 2.4b1, but when I connect the device, it doesn't show up or anything.

I tried the command:

sudo mkdir /Library/PrivilegedHelperTools

And received:

mkdir: /Library/PrivilegedHelperTools: File exists

Then I tried:

ls -al /Library | grep PrivilegedHelperTools

And received:

drwxr-xr-t 11 root wheel 374 28 apr 14:39 PrivilegedHelperTools

I'm running OS X Yosemite version 10.10.2 on a 13-inch MacBook Pro Retina.
