I've got a Wavlink WL-UMD502 usb-c docking station connected to a USB 3.2 Gen 2 port (USB-C) with an Ubuntu 22.04 5.15.0.56-generic kernel. I installed the device driver for the Wavlink docking station and followed the Readme.txt commands specific for Ubuntu which was: sudo depmod -a sudo update-initramfs -u Followed by a few reboots. Ethernet, Keyboard, and Mouse all go through the dock. I also tried to load the kernel module generated by the Makefile for the WL-UMD502 driver by doing: sudo modprobe rl8152.ko with the following output from *sudo dmesg* [ 4568.381336] usbcore: registered new interface driver r8152 I've also tried loading the *typec_displayport.ko* kernel module located in */lib/modules/5.15.0-56-generic/kernel/drivers/usb/typec/altmodes* but that's clearly for displayport support only. That being said, I have a sneaking suspicion that the type-c port on my laptop only supports DisplayPort format and not HDMI which is what the docking station and external monitors are. Although I am curious if grabbing an older kernel module for type-c might work because some threads I've found seem to show working type-c video output for Ubuntu 20.04 I don't have an alternate mode HDMI to USB-C adapter at this time so I can't test the port itself. Any thoughts? More information needed? A lot of people use Dell or HP docks lately. I haven't seen any questions related to Wavlink.
