USB Peripherals Not Working

Whenever I switch to my MBP, the peripherals connected to my dock stop working. This just started happening last night, and I didn’t update MacOS last night. I have used DisplayLink Cleaner to uninstall and then reinstall the driver. It’s still not working. Any advice?

Hello @NullVessel,

Thank you for posting on the Startech.com Community, I am sorry to hear about the difficulty you are having with our 129N-USBC-KVM-DOCK.

To help determine our next steps could I please ask:
- What is the year of your Macbook Pro?
- What version of MacOS are you using?

Something I would suggest doing in the meantime would be connecting the Macbook to the other host port on the dock to see if it works in the other port. I.e If the Mac is in port 1 and your other computer is in port 2, connect the Mac to port 2 to see if it behaves the same or not.

If it continues to act the same in the other port, try swapping the cables each computer is using to see if the behavior follows the cable or is still isolated to the Mac.

I would also welcome you to reach out to our support team via phone or live chat: StarTech.com Support. Live interactions through phone or live chat allow us to better understand what is happening, allowing us to provide the best support and can often have a quicker turnaround to a resolution. We can then update this post with the solution once troubleshooting has been completed.

We look forward to hearing back from you!

Thank you for the troubleshooting suggestions. I switched ports and switched cables per computer. I also tried one of the other 2 ports on my MBP to see if it happened to be the port I was using on the MBP. It continues to act the same.

One additional detail I left out of the initial post - the webcam connected to USB-A port on the dock has a flashing LED. The manufacturer troubleshooting indicates this is a connectivity issue.

I will call as you suggested but was hoping someone here on the forum had the same issue or resolution steps. The last time I called StarTech support they provided outdated instructions so it made troubleshooting that other issue more challenging, but I eventually got it to work on my own.

Thanks again!

Hi,
DId you find a solution to the above described issue. I am having the same issue with a latest MacBook Pro with Sequoia 15.5

My ultimate solution was to no longer use the product. I followed instructions from the support responses and even engaged over the phone. I found the Mac support was outdated and the technicians assisting seemed to be unfamiliar with the OS altogether.

I have the exact same issue: 129N-USBC-KVM-DOCK intermittently loses USB peripherals when switching hosts. When this occurs, devices connected to the dedicated USB 2.0 ports are not powered. Moving the keyboard to a 10-Gbps USB port causes it to receive power, but it is still not functional/enumerated. Both Macs remain running. Completely depowering the 129N for ~10 seconds and restarting the dock may restore USB functionality. Therefore the failure state persists within the dock and is cleared by resetting the dock, not the hosts.

Please let me know of any fix, the advertised functionalities don’t work, and it’s hurting my productivity.

Hello @LittleWheel,

Thank you for adding to the post and I do apologize that you are seeing a similar issue.

Would you be able to confirm what USB devices you are using with the dock (other then the keyboard, if any) and if all of them are showing the same issue when connected to the USB 2.0 ports? Does it occur in both directions or specifically when going from PC1 to PC2/PC2 to PC1?

I would also recommend contacting our Support team for a live troubleshooting session while you have the equipment available. This allows for more in-depth troubleshooting and can often lead to a quicker resolution. Once resolved, we can then post the solution here.
