I decided to have the Sony WalkMan reformat itself. MTP over USB working much better now.
Very odd that I could play MP3 recordings with the player without issues... only issues was removing files, copying new files to it. The thing that tipped me off to try reformatting the device with itself is I was seeing traces of recordings I had deleted yet in the playlist. Some of the letters in the listings were missing, but the content would still play properly. That told me deletes were not being completed properly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938645 Title: Ubuntu 20.04.2 getting kernel I/O errors connecting to Sony Walkman over USB using MTP protocol To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
