Confirmed to be not working on upstream kernel v4.15!
My ethernet adapter also stops working on upstream kernel v4.15, but I guess that's another issue.

Thank you for putting in the good work kind sir :)

My mistake, it does' work on upstream kernel 4.15, although the ethernet adapter does break.

I am using 4.15.0-65-generic x86_64 and the reader is not working. I am getting

mmc0: error -110 whilst initialising SD card

message in dmesg. Which 4.15 kernel was working for anyone?

Please follow instructions in comment #2 to try mainline kernel builds at https://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ .

On bionic, you may also want to try linux-oem-osp1 package, which has kernel driver rtl841l identical to current mainline kernel.

[Vladimir Makhnychev (makhnich)]

I'm still experiencing this issue on kernel 5.4.0-51-generic. The driver is missing, and the reader fails to recognize some types of SD cards.

I tried installing linux-oem-osp1, nothing has improved.
