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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1908779 Title: Usb doens't work with kernel 5.4.0-56 -58 Status in linux package in Ubuntu: Confirmed Status in linux source package in Focal: Confirmed Bug description: After upgrading to these kernel the usb ports are unavailable.
