ProMaster External Card Reader

My external card reader (ProMaster 6 in 1 USB) is not recognized by my MacBook Pro since I installed Mojave. It worked with High Sierra only a few months ago, so I know it's not the card reader or the card.

It could still be the card reader or the card but try resetting the SMC.
