My MacBook Air won't recognize my USB hub
Hi, I've been trying to get my MacBook Air to recognize my USB hub and can't seem to get it to work. Actually, I tried one hub and now I've bought another (thinking the first one may be defective), but still nothing is happening. I'm wanting to plug in a mouse and insert an SD card (has slots for both) to open the pictures taken on my camera, but I don't see a way to do it. I admit I'm a PC user, but shouldn't the memory card pop up somewhere in Finder for me to access the files just like it would on a PC? I'm running Catalina and have the USB hub plugged into the USB-C port.
Thanks for any help!
