USB-C hub with HDMI output not working
By Sophia Bowman
I recently bought a USB-C hub (QGeeM USB C Hub Multiport Adapter, 7 in 1) that has a HDMI port so I can use two monitors with my Thinkpad E15.
For some reason it's not being auto-detected and I can't turn the monitor on.

[ 287.589764] usb 1-1.4.4: Manufacturer: USB C
[ 287.589767] usb 1-1.4.4: SerialNumber: 000000000001According to thinkpad they do support HDMI through USB-C hub. So I am not sure why it's not being detected.
Thanks, Jon
