USB C connection issue.

Many reports of USB connection issues are related to a “bad” USB cable and replacement cables have resolved the issue.

At other times, these failures have been seen when using USB extenders or incompatible USB hubs, such as reported with a Sabrent USB 3 hub. It has also been reported that some touchscreens failed with USB 3.1 Gen 2 hubs but were okay with a standard USB 3 hub.

Directly connecting the USB device with a standard short USB cable normally resolves the issue and/or when connected directly via two USB-A/C adapters. Also when going through Apple’s own USB-C Digital AV Multiport Adapter (which is reported as USB 2 according to “ioreg -p IOUSB”).

If a USB extender is in use and failing, it’s possible that:

  1. There is not enough power going to the extender.
  2. The extender is not fully USB compliant.
  3. The extender is trying to handle HID and making incorrect assumptions.
  4. The extender is not compatible with the Operating System’s USB stack.
