I’ve been using the tbt3-udz dock with a few different laptops:
- 2018 13" macbook pro (previous work machine)
- 2021 m1 macbook pro (current work machine)
- Framework laptop 1165g7 configuration running elementary OS (based on ubuntu 20.04) (personal machine)
For the most part, the dock works as great. Even with the m1 macbook, I’m able to output 4K30fps to two monitors, which is not something I would have expected based on the marketing page for this product. One issue I am having is when running the dock with my framework under linux, the second monitor (connected via HDMI) will lose connection for about 1 second every couple minutes or so. I understand that linux is not a supported platform, and so I’m not asking for help debugging or fixing this, however I would like to request that Plugable considers supporting firmware updates to the dock via the Linux Vendor Firmware Service.
I have looked through Plugable’s support articles and some topics in this forum for information about updating firmware, and the only reference I can find to updating firmware for this product anywhere is in this topic, where support linked to a zip file containing a windows application for updating the firmware: https://support.plugable.com/t/tbt3-udz-msi-gs66-11uh-no-displays-detected-hdmi/22055/5
This leads me to believe that it’s not really intended for users to update the firmware for this device, even though there are updates (as evidenced by the linked thread). Is this really the case?
If it is possible to update the firmware on the dock through macOS, I have been unable to find any information on that. I would prefer being able to update through Linux anyway since my personal devices all run some form of Linux, but I do have access to an m1 macOS machine that I could use to update the firmware if needed.
To further my case for supporting LVFS, the firmware update manager on my linux machine can already identify the TBT3-UDZ as a device capable of receiving firmware updates, here’s the output of
Additionally, supporting LVFS doesn’t mean that Plugable will need to verify that any particular Linux distribution will work well with the dock, just that LVFS is capable of updating the firmware.
- I want to update the firmware
- I want to be able to do it from Linux in the future
- I can do it from a mac immediately if that is possible
- I do not have access to a windows machine to perform updates
Thanks for reading!
