USB ports not working on Thunderbolt 3 Dock Gen 2 (40AN)/ X1 Carbon 7th Gen (20QE) Win 10

2019-11-26, 23:02 PM

USB 2.4Ghz mouse doesn't work on any of the Dock 2 USB ports. Same mouse adaptor works right away when in the ThinkPad USB ports. Tried a couple of other USB devices, old an new, and none work in the Dock ports even though they work fine when in the Win 10 ThinkPad as well as in another older Win 7 laptop.

 

Checked all Win 10 drivers are latest versions, tried the disable/enable toggle, all to no avail. The Dock itself is hapilly driving two monitors and seems to otherwise work fine.  The always-on USB port on the back has power, and so does the one USB port on the front (but neither work for USB connected devices). This is a brand new setup, hoping for a trivial solution otherwise I will chuck this whole thing, at this age this should be plug and play.

 

Suggestions?

Thanks @Van_Lenovo - unfortunately no change as the latest drivers were already installed.  See screen shot when attempting to override with the driver pack from the support site.

Any other suggestions from anybody out there? Again, the docking station drives two monitors just fine, but none of the USB ports communicate with USB accessories that otherwise work fine when in the lenovo laptop USB ports.  Drivers are all up to date, according to the Lenovo utlities.

 

Right now, it looks like I'll be returning the docking station for replacement under warranty. Doesn't feel like a hardware issue to me, but I don't have time or appetite for troubleshooting a brand new product that should be plug and play.

Try the new firmware just posted, and report back. It applies to:

 

ThinkPad Thunderbolt 3 Dock Gen2
ThinkPad Thunderbolt 3 Workstation Dock
ThinkPad Thunderbolt 3 Workstation Dock Gen 2

I don't work for Lenovo. I'm a crazy volunteer!

Thanks @bananaman - unfortunately I punted to Lenovo and sent the thing back, waiting for replacement. I'll report on that when I get it.

Hi there,

 

I am having the same problem (for my mouse, keyboard, and headphones). I am going to try the firmware update (although I just purchased my dock a couple days ago so it probably already has the latest software)

Just wanted to check to see if you have an update on the status of your dock.

Hi,

 

I had the same issue, i.e. none of the USB ports or Audio output worked. I have a T480 which has 2 USB-C/Thunderbolt type ports. I was confused which one to use, but the correct one had the lightening bolt symbol. The display(s) worked but not USBB/Audio. Then, eventually, I saw this in the User Guide(Page 6).

 

 

After I changed this, it all worked perfectly! It's fair to say that it is documented but I found the 'Quick Setup' pamphlet pretty confusing, nothing said which laptop port to use and I had to get into the User Guide before finally finding the solution.

 

Best regards,

Richard

Wow!

This solved my USB problem.

 

Hi Richard,

Sometimes, it is good reading the user guide, which I didn't.

 

Thank you so much

Gideon

Hi,  I am experiencing this issue.  After reading the thread I don't see what was exactly seen on the manual that solved the problem.

 

I tried upgrading the firmware without results, and I plugged the wireless mouse usb adaptor to the port on top of the VGA port without success.

My usb ports are not recognizing my wireless mouse or keyboard, when I plug my headset to the usb ports it doesn't recognize it either

 

Any guidance would be appreciated,

 

Thanks
