Description Andrew 2023-11-08 21:38:40 UTC 
With kernel 6.5.11 usb3 does not work at all. 
With kernel 6.3.8, the usb3 port works if the device was connected before powering on the laptop; after reconnecting, the usb3 port stops working. 
There are no such problems with Linux kernel 5.15

Comment 1 Mathias Nyman 2023-11-09 14:52:49 UTC 
Can you try git bisect to find the offending commit?

looks like xHC host does see something on port 3-1, but can't get
it enumerated properly.

dmesg shows some issues with phy and regulators:
samsung-usb2-phy 12130000.phy: supply vbus not found, using dummy regulator
exynos5_usb3drd_phy 12100000.phy: supply vbus-boost not found, using dummy regulator

Maybe there is an issue in turning on regulators, supplying ports with power?

Enabling dynamic debug for usbcore and xhci at boot could show more info, can be done by adding:

usbcore.dyndbg=+p xhci_hcd.dyndbg=+p

to the kernel cmdline.

Comment 4 Andrew 2023-11-09 19:10:30 UTC 
Unfortinally 'usbcore.dyndbg=+p xhci_hcd.dyndbg=+p' did not gave more information about usb3 issue. Maybe I need to add some extra option to kernel config and recompile?

I tried to plug in mouse to usb3 port instead of flash-drive, and there was no light under mouse. And 'usb usb3-port1: connect-debounce failed' appeared at dmesg.

Comment 7 Andrew 2023-11-10 09:27:08 UTC 
I applied configpatch and rebuilt the kernel. With debugging enabled usb3 port works fine. That was unexpected for me.
Comment 8 Mathias Nyman 2023-11-10 14:37:49 UTC 
The debug output causes some latency, that could be one reason.

The log for example show that usb3 bus was just about to be suspended before it detected something on the port:
