Wired mouse and keyboard not working with USB 3.0 Hub

I am trying to use a wired mouse and wired keyboard with my 13" Dell XPS running Ubuntu (kernel @ Linux 5.19.0-38-generic), which has only two USB-C ports, via a USB docking station.

The wired mouse and keyboard are not working with USB hub when connecting to my Ubuntu device. The same setup works in the same hardware if using Windows instead.

More than one wired mouse was tested (they all work in a different computer). Wireless mouses with USB adapters are also not working.

My hub recognizes the DP connection for the external display, and also recognizes external HDs, but does not recognize smaller flashdrives.

When testing the same wired components on an HP Zbook running the same Ubuntu version, via regular USB port (not through the hub), all devices work.

The hub powers whatever wired mouses I connect there.

# Shows no diff when using or not using the USB hub with wired mouse and keyboard

If I try sudo dmesg -Hw with the hub connected and later plug in the mouse or keyboard, nothing shows up.

Commenting out any usb lines within the only file at mambaforge/lib/udev/rules.d, which was 90-pulseaudio.rules, according to a similar topic.

Furthermore, I have also made a probe on the PC usikng, with which I couldn't really get anywhere, but can provide here if it's any help.

There seems to be a related bug described here, but... when I have navigated to my own /lib/modules/5.19.0-38-generic/kernel/drivers/usb, the only file here is ledtrig-usbport.ko, instead of the multitude of files shown in any of the related releases (e.g., https://github.com/torvalds/linux/tree/v5.19/drivers/usb/core). Wonder if this is somehow pointing to missing files on my end, even after having a clean Ubuntu install and sudo apt-get update frequently.

Thanks in advance!!

What is the version of Ubuntu that kernel could be on a number of different versions.

My bad - it's a fresh Ubuntu install with the latest Ubuntu 22.04.2 LTS.

This might sound like a stupid suggestion but did you try flipping the USB-C connection over to see if that resolves the issue? One guess I have is that the internal MUX that directs the USB-C signals about is not working as it should. By flipping the connector over that moves which wires are carrying the USB 3.x and DisplayPort signals. By working with Windows and not Ubuntu my guess is the dock is simply poorly designed and is in violation of the published specification, and there's not likely a driver fix for that.

@David I did include the kernel on the post, just not the Ubuntu version! Kernel is Linux 5.19.0-38-generic which is not as recent as could be, but would require a manual kernel update.

@MacGuffin no such thing as a stupid suggestion. I just tried doing that and trying 4x on both ports, and the issue still persists. Hmmm I understand your argument, but seeing other places such as [here](https://bugzilla.kernel.org/show_bug.cgi?id=213839) I am nearly convinced there is a small issue. My laptop not having the proper files on `/kernel/drivers/usb/core` might be part of the issue? And I don't know how to properly setup these files there, which seem to be part of the kernel itself.

Turns out I had an extension cable (USB-C to USB-C) which was the culprit. It worked fine in Windows, but apparently made part of the hub (the USB-B ports) incompatible in Linux.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
