I was trying to figure out another problem I ran into while upgrading (https://bugs.launchpad.net/ubuntu/+source/samba/+bug/2092836), which involved booting between Ubuntu 20.04 and Ubuntu 22.04 a lot. Sometimes, when booting back to Ubuntu 20.04, the USB Ethernet was not working (same symptoms as reported - not visible in lsusb) and it needed to be unplugged. This was always when going from 22.04 -> 20.04, never the other way around.
My system has been running 20.04 for a few years now. When I initially said the USB Ethernet worked in 22.04, it's because doing a do-release- upgrade to 22.04 did not immediately stop it from working. That was the extent of my 22.04 experience. Also possibly relevant, I have a USB SATA adapter with a hard disk attached normally (for backup purposes) and according to lsusb, this port is attached to the same hub as the type-C port the USB Ethernet is attached to. The booting between Ubuntu versions I was doing involved a similar USB SATA adapter with a SSD (hosting Ubuntu 22.04). The hard disk was not connected at this time. My system is currently back on 20.04, but since I figured out the other issue I had, I may try getting it on 22.04 and leaving it there for a while, assuming that the USB Ethernet proves to be reliable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2092711 Title: USB Ethernet adapter does not show up on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2092711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
