https://bugzilla.kernel.org/show_bug.cgi?id=220181 Bug ID: 220181 Summary: Users across distributions see “config failed, hub doesn’t have any ports! (err -19)” from xhci_hcd at boot. Product: Drivers Version: 2.5 Hardware: AMD OS: Linux Status: NEW Severity: low Priority: P3 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: 6svcyk03@xxxxxxxxxxxxxxxxxxxxxxxxxx Regression: No At boot, I see the undermentioned in red in `dmesg`: > ~~~log > config failed, hub doesn't have any ports! (err -19) > ~~~ I've one entry for each boot in `journalctl`. Using the first section of the error: > ~~~YAML > hub 12-0:1.0 > ~~~ ...I believe that I've ascertained what the cause is. Using `lsusb -t`, I find: > ~~~YAML > /: Bus 012.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/0p, 5000M > ~~~ `Driver=xhci_hcd/0p` means it has 0 ports, which is invalid, hence the error. I tried to `readlink /sys/class/usb_host/usb12` it to ascertain what the cause is, but that fails, because the device unsuccessfully enumerated. Consequently, I used `readlink /sys/bus/usb/devices/usb12` to verify the device ID: > ~~~log > ../../../devices/pci0000:00/0000:00:08.3/0000:5a:00.0/usb12 > ~~~ When known, I used `5a:00.0` to locate the cause with `lspci -s 5a:00.0`: > ~~~YAML > 5a:00.0 USB controller: Advanced Micro Devices, Inc. [AMD] Raphael/Granite Ridge USB 2.0 xHCI > ~~~ It's the virtual "Advanced Micro Devices, Inc. [AMD] Raphael/Granite Ridge USB 2.0 xHCI" USB controller, not exposing any ports despite the driver purportedly requiring it. However, there obviously aren't ports on a virtual device. At https://discussion.fedoraproject.org/t/what-does-config-failed-hub-doesnt-have-any-ports-err-19-mean/153954, I cite corroborations from Kali Linux, Ubuntu, Debian and Fedora. However, I've also received a personal e-mail from an interested party who claims to reproduce this on openSUSE. -- You may reply to this email to add a comment.
