t480s/dock:40ah - USB HID devices not found with docking station

2018-03-21, 10:34 AM

Title says all I guess. Mouse and keyboard are not working though the dock (the new mechanical/thunderbolt kind) under the pre-installed windows as well as with ubuntu 18.04 alpha.

The windows/Intel thunderbolt software does not show devices as well.

I heard that I should've seen dialogs asking for permission to use the dock as  a trusted device of somekind. I haven't seen this.

Strangely network and screens work fine.

 

I've looked at driver updates etc, but I seem to be up-to-date.

 

Any ideas?

 

/update

Problems seem to be limited with usb 2.0 devices. However usb 2.0 devices also do not work on the usb3.0 ports on the dock

Hi guys,

I did a review of a Pro Dock for my T480s after CES 2018. The unit that I received for testing prior to CES was a pre-production model so it arrived without final detailed specs. I recall updating firmware and an audio driver, but at this point I see no model numbers on it as it was for review and labeled "Not for Sale". Therefore, I cannot be sure that it is the exact model that you are interested in.
When I was testing it, it performed satisfactorily and all the ports worked. Other than that, I wish I could be more helpful. If I find anyone who also did testing and has more information to add I'll let you know.

Called Lenovo, and they supplied another  dock. It worked for 10 minutes. So I called Lenovo again; a third dock would be sent at that point. Next day, 1 hour before  the third dock would arrive, the second dock started working. At that point I thought it could be laptop which is malfunctioning, so I tried the first dock again.. no game. The third dock didn't have any issues at all.

 

Quality assurance seems to be bad on these docks.

Note: this not a Thunderbolt dock, this is USB C.

Then what purpose is it hooking into the thunderbolt port on the computer? 

 

The dock connects in via USB-C for power, then another USB-C port and the thunderbolt port

There is no such thing as a Thunderbolt port. It's a USB C port capable of Thunderbolt Alternate Mode and this dock is using DisplayPort alternate mode instead apparently. I have no idea why didn't design just a single USB C dock with the other USB C port still open.
