Hello, Thank you for your feedback. With that information we know this is probably a regression introduced on 5.4.0-56 and that it is fixed on mainline kernel.
The current linux version in focal-updates is 5.4.0-65.73, could you please try it? If this version is still broken, it would be also be good to test the version in focal-proposed (5.4.0-66.74). Both of these version have several bug fixes. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Please also double check if you have the linux-modules-extra package installed for all of the tested versions. Thank you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1908779 Title: Usb doens't work with kernel 5.4.0-56 -58 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1908779/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
