Hi, I started Ubuntu 20.10 on a USB Key and the keyboard was working fine on kernel 5.8.0-25. I "kind of" installed the last 5.11-rc4 kernel on my Ubuntu 20.04 and the keyboard was working fine too (I were only able to test it in a terminal mode).
Since Bus and Devices values where differents in `lsusb` outputs, I thought maybe the Intel Bluetooth chipset was conflicting with other USB devices. I disabled it in the bios as well as blacklisted all bluetooth drivers throught a /etc/modprobe.d/blacklist-bluetooth.conf file, but nothing worked. So I don't know, maybe there's an USB cache somewhere and a clean reinstall would solve the issue or maybe something has been broken after 5.8.0-25 and fixed in 5.11-rc4. Anyhow I'll stick back on a 5.4 kernel for now and check if the issue will disapear by itself. Thank you for the help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912908 Title: USB keyboard not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912908/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
