Public bug reported:
I have an ethernet adapter (ASIX Electronics Corp. AX88179 Gigabit
Ethernet) attached to a USB-C port of my laptop. After update to kernel
5.4.0-90-generic it stopped working again. Same problem with
5.4.0-91-generic. Detaching and reattaching the adapter doesn't help,
but after suspend and resume it starts working again, until the next
boot. I had the same problem earlier and it was fixed here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939638 , but the
bug got reintroduced in kernel 5.4.0-90-generic most likely due to this
patch:
* Fix cold plugged USB device on certain PCIe USB cards (LP: #1945211)
- Revert "UBUNTU: SAUCE: Revert "usb: core: reduce power-on-good delay time of
root hub""
I'm running Ubuntu 20.04. USB2 ports work without problems.
