Hi, would it be possible to provide the dmesg output after boot? Could you also provide the output of 'lspci -nn | grep USB' since since a lot of these issues seem to be USB card specific and I am unfamiliar with your hardware.
As Jarkko mentioned, in 5.4.0-90 there were some patches that were reverted to do with https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1945211 that might be now affecting your machines.
