Hi all. I have a fresh install of Kubuntu 20.04. Secure boot off, machine is dual boot with Windows & Kubuntu on their own drives.

System info:
Operating System: Kubuntu 20.04
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8
Kernel Version: 5.8.0-59-generic
OS Type: 64-bit
Processors: 12 × Intel® Core™ i7-10750H CPU @ 2.60GHz
Memory: 15.5 GiB of RAM

I have followed all the howto's and when I run lsusb -d 17e9: I get no results, however if I run lsusb I get the following:
Bus 002 Device 004: ID 0711:5601 Magic Control Technology Corp. USB3.1 Hub
Bus 002 Device 003: ID 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet
Bus 002 Device 002: ID 05e3:0620 Genesys Logic, Inc. USB3.1 Hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 0951:1718 Kingston Technology
Bus 001 Device 004: ID 0c45:7663 Microdia
Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 005: ID 8087:0026 Intel Corp.
Bus 001 Device 003: ID 5986:211b Acer, Inc HD Webcam
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The USB ports (And I would wager the LAN port) on this device works without issue. The device also works flawlessly on Windows 10 so its not a damaged device. The VGA & HDMI ports work on Windows but nothing on Kubuntu. If it means anything, I tried this on the same machine under a Ubuntu Budgie install as well with no luck.

Here is the link to the device in question:

Any help or advice?
