This got broken again in 5.4.0-90 (Ubuntu 20.04). USB2 ports work but USB-C don't. Reattaching USB plug doesn't help, but after suspending and resuming USB starts working again, until the next time I restart the computer. The reason seems to be that the temporary fix was reverted:
* 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""
And if some proper fix was made, it doesn't work in my case.
