Have you found a way to do this in Catalina? My MBA's card reader stops working after a few hours of uptime (it works great after a reboot). Before 10.15 I was able to fix this with these commands, but now I just get an error message (I have SIP turned off):

(kernel) Can't remove kext com.apple.driver.AppleUSBCardReader; services failed to terminate - 0xe00002c7.
Failed to unload com.apple.driver.AppleUSBCardReader - (iokit/common) unsupported function.

Sorry @ebertek unfortunately I changed my MB and not followed what happened with recent updates. I think it changed the way it manages IO under the hood but I haven't any clue or way to reproduce it
