Can I connect another adapter through the USB-C port on the side? Will I be able to plug in multiple external HDD/SSD drives into the ports with the USB-C and adapters? Will this work on the MacBook Air? Will this support the Apple USB SuperDrive? Does this support the 2017 MacBook Pro (13' w/o TouchBar)? Description says only 2018-19. Another reason for your Mac not recognizing external drives is a dirty or loose connection between your cable, USB-C multi-adapter, Thunderbolt 3, or other connecting ports. So check your cable, your dongle (if used), any additional adapters, and the ports on both computers and drive to ensure that they are clear, clean, snug and fit tightly to.
If the Finder preferences are set to mount external drives to the desktop we will need to determine if the USB flash drive is detected by the computer Waterfox 56.2.4 for mac.

If you see Flash Drive listed under the USB hub the USB flash drive is detected properly. You can verify is the drive is mounted by Selecting 'Go > Go to folder' from the file menu and typing /Volumes/ (Note: This is case sensitive). This will open the mount point for all drives connected to the Mac computer. You should see the drive mounted here.
If the USB flash drive is not listed under USB hub please verify other USB devices work properly and if possible test the USB flash drive using a different computer.If the USB flash drive is not detected on other computers or if other USB devices are working properly on this Mac then most likely the USB drive is not functional.
