In the DisplayLink logs this is shown as transfer errors and device unavailable. In the system log you can see transfer and wake errors in both USB2 and USB3 devices and then only the USB2 part of the hub is reset while the USB 3.0 part of the hub is longer there, together with the DisplayLink device.

USB 3 is difficult hardware-wise because of both higher speed and more advanced power management so looks like something is borderline in your use case and fails.
I'd think about the USB-C adapter as the first thing to try and replace, but you may also want to try with a different, shorter, USB cable between the Targus and the adapter.

A separate issue is with the monitor. I'm seeing 8 different monitor description files so unless you are trying eight different monitors it is likely that there is a problem connecting to the monitor. Most likely the connection, I'd check the DVI cable.

Bes regards,

Hey Carlo thanks for the quick and detailed reply,

Just as a bit of context, I work in an office environment with hotdesks - some desks have two monitors and some have one. But all desks have the same peripherals and LAN connection. A colleague of mine has recently started using a Macbook Pro 13" (older model) and she hasn't had any of the issues I'm having which is why I thought it's either a problem with drivers or the USB-C adapter.

I'm sure you understand that these adapters aren't cheap, so I'm a bit reluctant to go out and buy another one just for testing. I might have to wait until I come across someone else with a different adapter to try.

EDIT: Unless I get something like this?
EDIT2: Bought an Apple USB-C to USB adapter this morning and it doesn't work either (see attachment + link below)

Out of interest, do you know if others are having problems with their adapters? Any of which using the newest Macbooks?

Thanks,
Curtis
