Sony XQD reader not working with 2019 MacBook Pro 16"

I have a Sony XQD/SD reader (model MRW-E90) that has the USB 3.0 Micro B connector on the back. If I use a USB-Micro B to USB-C cable to connect it to my 2019 MacBook Pro 16", it is not recognized. If I use any kind of USB hub in between, like Hyper Drive's USB-C hub, it works even if I use the same USB-Micro B to USB-C cable to plug it into a USB-C port on the hub. I don't understand why I can not connect this reader directly to my MacBook with the appropriate cable. I've tried all 4 USB-C ports on my MacBook and even tried flipping the cable (because sometimes that seems to matter). I've also tried multiple different cables as well as one with a USB-A end and a USB-A to USB-C connector in between.
