DisplayLink Forum - How do I know if I am using DisplayLink?

Hello everyone, sorry for what might sound like a stupid question, but how do I know if I am using DisplayLink? I have a 15" TouchBar MacBook Pro running High Sierra 10.13.3 connected to:

Two LG 4K panels via a USB-C to DisplayPort adapter for each monitor.
One HP LP3065 panel via a USB-C to Thunderbolt adapter to an Apple Dual-Link DVI adapter to the Dual-Link DVI interface on the monitor.
One Sun Microsystems 24.1" panel via a USB-C to HDMI (in a hub) adapter to an HDMI switch to an HDMI to single-link DVI adapter to the panel.

I have the following DisplayLink driver installed:

Code:

$ kextstat | grep -v apple

although I don't know if I need it installed. How do I know if I'm using it, and if I'm not, how can I safely remove it from my system? I am experiencing Watchdog resets during sleep and I want to rule out this driver being the cause.

Also, should I hold off updating to 10.13.4 because of all the kernel panics I am seeing on this forum?

Thanks for any help!
