    Looking at your comments on the bug report, seems like you suspect snap as a possible cause. This seems doubtful, since hardware compatibility is provided by the Linux kernel, not by snapd. The description resembles a typical kernel *reversion*. Nevertheless, feel free to test your card-reader with a non-snap browser and see it it works any better, so you can confirm or rule out snapd as the culprit. Who knows? Maybe you are right. – user535733 Aug 13 '22 at 23:52

Run these two commands:

sudo systemctl start pcscd
sudo systemctl enable pcscd

The first starts a service that is necessary for the card to work, the other one ensures it will be running on startup next boot. Source comment #14 here: https://answers.launchpad.net/ubuntu/+question/701636#12

    Thanks! This saved me on Ubuntu Unity 22.10. I really need this, so I was about to change distro, when I saw your answer here and decided to give it a shot first -- and it works. No need to change distro for this, any more. The only difference is that I used "start pcscd.service" and "enable pcscd.socket", as suggested by autofinish in my terminal. Works the same. – Franko Nov 16 '22 at 14:11

I've just experienced this as well. My temporary solution was to remove the snap package and force Ubuntu to use the ppa/deb package. Note: I wasn't the one that came up with this, I found it here: https://www.omgubuntu.co.uk/2022/04/how-to-install-firefox-deb-apt-ubuntu-22-04

sudo add-apt-repository ppa:mozillateam/ppa

followed by this all in one block

echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox

then

sudo snap remove firefox && sudo apt install firefox

and this is to try to keep the snap from overwriting the deb

echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox
