I'm running debian 4.19.0-10-amd64 on a NUC10i7FNH1 and what I need works except for the card reader. I get:
mmc0: Unknown controller version (5). You may experience problems.
mmc0: SDHCI controller on PCI [0000:02:00.0] using ADMA 64-bit
mmc0: 1.8V regulator output did not became stable
I've installed all the latest BIOS and added firmware-iwlwifi and firmware-misc-nonfree but can't find which package has Genesys drivers.
To add to my confusion, It was intalled on a NUC10i7FNK2 here, and the reader was recognized. I thought that was the same hardware.
