I recently purchased a laptop, The Asus Laptop 15 X515JA. I needed the extra ports provided when using a usb-c hub with the laptop.
Upon trying to use a usb-c hub. It showed up with error that the device is not recognized.
The usb-c hub's ports behaved as followed
The usb 3.1 ports only ran at usb 2 .
The HDMI port just didn't work at all.
The ethernet worked.
I tested with another hub and got the same results.
I updated the drivers in device manager and that still did no solve my issue.
