my usb port is not recognizing my SD card reader

I have shut down my mac, restarted it, and my SD card reader is not being recognized in my usb port. However, my lighting cable works just fine. I have tried to different SD card readers, but neither of them work. I believe I have also successfully reset my usb ports.

MacBook Pro 15″, OS X 10.11

My MAC doesn't recognise my SD card reader, what can I do? My SD card reader has stopped working. It shows up as hardware in my system report but when I put any SD card in, it won't find it or read it. It worked last time I used it but that was a couple of months or so ago. I have rebooted the machine a few times and this does not work. Any advice would be appreciated. Thanks

SD Card Reader While loading pictures onto an SD card, it appears my reader has stopped working. It appears to still be recognized in my hardware, but I cannot get it to mount multiple SD cards - I have tried restarting the computer and cleaning out the port numerous times. This is for a Macbook Pro, late 2012. This issue appears to have arisen after I performed first aid on an external hard drive that was acting up - any chance these things are related? Any suggestions as to how I can get it to recognize my SD cards again? Thanks!

SD Card Reader Not Working I recently updated to Monterey 12.6.2 from 12.6.1. After the update, the SD Card Reader no longer works. Worked fine up thru 12.6.1. Have tried multiple SD cards and none will work. Tested the same cards in an external reader via USB 2.0 All test cards mounted and worked correctly in the external reader. The Mini had successfully read all the test cards via the onboard SD Card Reader before the update. Followed suggestions to "clean" the slot with a non-metal toothpick and used compressed air to blow out the slot. Neither helped. Found a suggestion to restart the USB daemon via Terminal. Did not work. I've seen this problem discussed about 12.6.1, never on 12.6.2. The solution to fixing on 12.6.1 was to update to 12.6.2. That's when mine stopped working. Any help would be appreciated. 2014 Mac Mini, 16GB Ram, 1TB Fusion Drive
