            Bug ID: 218118
           Summary: USB3 port does not work on Chromebook XE303C12 with
                    Linux kernel 6.5.11
           Product: Drivers
           Version: 2.5
          Hardware: ARM
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: quark@disroot.org
        Regression: No

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 from Mathias Nyman (mathias.nyman@linux.intel.com) ---
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.

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.

I applied configpatch and rebuilt the kernel. With debugging enabled usb3 port
works fine. That was unexpected for me.

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:
