If your Type-C Pro Hub with Ethernet isn’t detected, try these steps:

• Make sure both USB-C connectors are fully seated in the two side-by-side USB-C ports on your MacBook. The hub does not work with MacBooks that have a single USB-C port.
• Open System Information > USB to see if it appears.
• Test on another compatible MacBook to see whether the issue is the adapter or your computer.

If the problem continues after these steps, submit a support request.
