Public bug reported:

Hi,

Ubuntu 20.04 fails to discover a micro SD card inserted into the "O2
Micro, Inc. SD/MMC Card Reader Controller (rev 01)". I currently have no
other card available for testing, but the one I have tested with is a
Lexar 32 GB 633x microSDHC UHS-I, according to the packaging. It works
well in a digital camera.

I tried intstalling exfat-fuse and exfat-utils - that didn't cut it.

Thanks!
