Device shows as "USB Storage"

I recently purchased TBT3-UDZ which is working with my work PC (HP Elitebook). When I try to connect it to a Lenovo desktop via the USB-C port it is recognized only as “USB Storage”. With my work, I need to be able to swap between computers and so I will need to return this hub if I can’t resolve this. Are there any fixes?


Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

The dock does have a USB storage device in it (the front card reader slots), so it is not unexpected to see that show up. May I assume other dock functions are not working as expected?

Please note that not all systems with USB-C support docks like this. Most desktops lack required optional USB-C features such as USB-C VESA DisplayPort Alternate Mode to enable video output and may only support USB data devices (keyboard, mouse, flash drives, etc). I suspect this is the case with your Lenovo desktop, that it has a “data-only” USB-C port and will not be fully compatible.

To be sure, please let me know the full model number of your Lenovo desktop so we can check if it has the required USB-C features to support this dock. If it doesn’t, we would have other docks that may work better for use between your two systems that don’t require underlying USB-C optional features.

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!

Thank you very much for your response. Yes, you are correct - no other functions are working on the dock as it thinks it’s just an external drive. The model Lenovo is a ThinkCentre M75q Gen 2. Here are the tech specs

Thanks for the info!

Looking at the specifications on the Lenovo website, it would appear this system only supports USB data from the USB-C port. There is no mention of USB-C DisplayPort video functionality. This would certainly explain monitors not working through the dock when attached to this system. Unfortunately, based on this info you’ll likely need to use a different docking product between the two systems. Due to the limitation of the C port on the desktop, we’d need to recommend a more traditional USB 3.0 docking station that doesn’t require any special functionality from the system to support it. However, a USB 3.0 dock won’t be able to charge your laptop like the current TBT3-UDZ can.

Do you need any special features like 4K video support, or will standard 1080p video be good enough in this case?

Best wishes,
