I got a brand new laptop, and for some reason my old USB-C hub doesn't connect.
It seems like it does get detected and recognized, as some outputs show the manufacturer etc. but it keeps connecting/disconnecting multiple times per sec, with these errors:
device not accepting address 13, error -71'hub_ext_port_status failed (err = -71)device descriptor read/64, error -71unable to read config index 0 descriptor/allcan't read configurations, error -71config failed, can't get hub status (err -5)Failed to suspend device, error -19
This is the USB-C Hub in question: Ugreen 5-in-1 USB C HDMI Hub
Laptop: IdeaPad 5 Pro 14ACN6 (psref)
I suppose what's happening here is that, the port on this device is a USB-C 3.2 Gen 1, and not Thunderbolt port. It supports DisplayPort, but not HDMI, so what happens is that the device detects a hub with a HDMI and disconnects it, is that a possibility?
Ironically the device has a separate HDMI port.
I was under the impression that USB-C 3.2 will support USB Hubs with any display output - whether HDMI or DP. Or am I wrong, are HDMI USB Hubs only supported on Thunderbolt ports?
Additionally scanning through similar issues, some users reported that their USB Hubs with HDMI work on this exact device. Maybe it's only certain hubs/HDMI versions that USB-C 3.2 supports?
I tested this out on both a fresh Windows Home installation as well as Ubuntu.

When doing lsusb
I had to actually "catch" the above line, as it mostly hangs and often doesn't output the Genesys hub that is (not) connected.
I also looked into /sys/bus/usb/devices

It seems again the USB3.1 Hub is detected, but the above cat
hangs and I had to run it multiple times in order to catch the output.
