Unfortunately, with perhaps a recent update of my Mac OS, it appears no USB hub devices (whether enabled with DisplayLink or not) are showing up as "detected" under the USB bus, even if the device is functioning. I will contact the manufacturer of the hub. In the meantime, any thoughts on what might be the issue?/Ĭonfirming I received the following message from support. I will share the results of my help request in here once I hear back. I sent an email to support with my question a couple days ago and have yet to hear back.

Monitor 1: LG 27" Class FHD IPS FreeSync Monitor (lg-27MK430H-B) What I notice is that the USB-C hub doesn't show up in the USB Device Tree (see attachment with screenshots), however, I do notice that *any* USB hub - whether it works or not - does not show up on the Device Tree.ĭevice: uGreen 9-in-1 USB-C Docking Station (SKU 90912) When I run the System Report and look at USB devices. I've followed all the troubleshooting suggestions. I have uninstalled - rebooted, and reinstalled/re-configured/rebooted again the DisplayLink 1.8.1 driver. I returned and purchased a replacement model of the uGreen (90912) dock, tried that one out and nothing changed. Then, after undocking (took my laptop to the office) and reconnecting my laptop to the USB-C dock, both monitors started to say "no signal detected". My uGreen 9-1 USB-C (90912) dock worked beautifully for one session (a couple days).
