8 in 1 dongle USB 3 ports not working

I recently bought an 8 in 1 USB-C dongle for use on my Asus C302A chromebook. The unit looks nice and is well built.

Both SD card slots work fine, but the USB 3 ports are not working. I plug in the dongle to my USB-C port on the chromebook, and insert a USB stick. The stick is not detected, no matter which port I use. Using a dongle from a different manufacturer, the stick is detected properly on all USB 3 ports.

Looking at the manual it ambiguously describes that a driver may be needed. I’m wondering how this works on a chromebook, if at all. I’ve not yet tested the HDMI, ethernet, or PD ports.

Anyone else have this problem? And if so, was it fixable, or just a bad unit? Or does this dongle just not work on chromebooks?

TIA

The USB 3 ports on the 8 in 1 USB-C dongle are working OK on my Win 10 laptop. So are both SD card ports. It just doesn’t work on my Chromebook. I’ll keep the unit because I have another one that works on my Chromebook. I’ll use the 8in1 on the Win 10 laptop.
