DisplayPort USB-C monitor not detected

Rumengol · 2025-06-02 07:38:45

Hello,

I am trying to connect my laptop (MSI Katana 15 B13VGK) to two HP monitors with a USB-C cable and they are not detected.

- It works fine on a Windows laptop.
- The monitor also works as a hub, the keyboard and mouse connected to it are detected and function correctly.
- KDE Plasma Wayland

udevadm cycle through this:

I guess something fails with the USB connection, even though it is working fine for other peripherals? I don't know where else to look.

(sorry I'm kinda new to linux so I may not be of too much help)
My first thing that I saw was the errors noted in dmesg:

xhci_hcd 0000:00:14.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state.

(abbreviated for Transfer Ring dequeue Pointer command failed due to incorrect slot or endpoint state)

This could be linked to some firmware issues, though your lspci results do show the correct drivers/kernel modules under the USB Controller

USB controller: Intel Corporation Alder Lake PCH USB 3.2 xHCI Host Controller (rev 01)
        Kernel driver in use: xhci_hcd
        Kernel modules: xhci_pci

Just to check though, you could run

lsmod | grep xhci

and check the results (and then if not obviously enable it with sudo modprobe xhci_pci)

I feel like all I've done so far is just state the obvious... anyway

One potential issue (although since your laptop is from 2023 or later, it might be on by default) could be the XHCI hand-off setting in BIOS, which when disabled essentially hands USB 3.0 control to BIOS rather than the OS (used for legacy compatibility, and therefore decreases data transfer rate)

I do notice your laptop uses an RTX 4070, so maybe this answer could be a fix (ik it's ubuntu, but...) - https://askubuntu.com/questions/1105332 … 79#1134579

Perhaps I could do with more info (like xrandr and lsusb output) but I'll keep it simple (for my benefit )
Lmk if anything helps

Thank you for your answer!

I have some additional information : when I connected the laptop to a single monitor using the same kind of cable everything worked fine, but today I tried on a duo again (different than the first one) and it failed like last time. The two monitors are connected to each other by a DisplayPort cable, and somehow even when the DP cable is unplugged I have no output. Additionally, the main monitor (to which the USB-c cable is plugged to) is the one connected to the keyboard and mouse (both work) as well as ethernet (which doesn't work either). Could it have something to do with the monitor configuration when there are two of them, somehow?

Either way, here are the outputs you asked for:

> lsmod | grep xhci
xhci_pci               24576  0
xhci_pci_renesas       24576  1 xhci_pci

I believe it means it is on, I also check the BIOS and it is enabled there too. The nvidia approach didn't seem to work unfortunately,

Thanks for the response!

This is kinda puzzling for my little knowledge, and it does seem so for most people regarding some USB stuff (despite similar issues being somewhat populated):

I just decided to try and have a look into what the error code -71 meant that was listed in the dmesg log

usb 2-3.1: Failed to suspend device, error -71

After having a search for around 15 minutes I found few and varying results (as these codes do not seem to be documented).

One to try might be this, which does seem logical to me, as it has to do with endpoints, which were warned about in

xhci_hcd 0000:00:14.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or *ep* state.

as previously discussed: https://www.spinics.net/lists/usb/msg02644.html, which I then found similar results for in https://forum.manjaro.org/t/how-to-get- … work/46927.

The thing here being to add the line

options usbcore use_both_schemes=y

to the file /etc/modprobe.d/modprobe.conf

The initial descriptor under the USB controller interface of lspci did throw me off any firmware issues, as I couldn't find anything about that, but the new lsmod output did contain the module

xhci_pci_renesas

which is interesting as I was reading a forums post about such issues with a Renesas USB controller here, where the possible fix would be to install the upd72020x-fw package (which is, however, AUR rather than a core package).

So if you suspect that might be the actual USB controller then give it a go, but for now I can't really think of or find anything else...

I would have zero idea as to why a single monitor setup worked over the dual though, but perhaps you could check the monitor setup, maybe in its settings or the physical connection.

Again, sorry if I'm unable to help

Well now I am very confused...

Today I wanted to try another dual monitor before trying your suggestions, and to my surprise it worked on the first try! So at first I thought it may be because it is the same model of monitors (we have 2 different models, so I thought maybe the issue occurs if it's a dual monitor of 2 different model), but it's not that. It seems I was just unlucky with my first few attempts.

I will keep experimenting with the not functioning monitors and keep you updated if I find out the problem.

Thank you for your help!

airbus777neo · 2025-06-06 16:37:27

Very interesting...

Well I suppose I can leave it for now then, until you potentially face any more issues/find the cause?

Anyways, glad to help
