There are a number of different SD card readers, each of their drivers have unique issues. With one specific card I had my laptop reader failed to read the card at all, but when put on a different linux machine it worked fine. That was an issue because the specific SD card lied about voltages it could use and one driver trusted its info and the one that worked did not This specific bug I did find details specific to exactly my card and my read in the kernel. My card is a sandisk extreme uhs-3 sdxc. So google for your card (lsusb and/or lspci should show the reader, dmesg should also.
The usb bus probably stays powered across a reboot, so if the device fully locks up and won't accept a reset during boot it will stay locked up and continue to mess up the usb port. .
