Re: T480 Does not recognize USB ports on Pro Docking Station

2018-12-24, 18:57 PM
I can confirm that I get my T480 working with Linux Mint 18.3. After installing a Win10 machine where I installed Lenovo System Update 5.0 which installed 2 updates for the Pro Dock (USB and DP). Then I activated Thunderbold in the BIOS without Assistant Mode in order to get it working on Windows 10. After applying the Thunderbold FW update (I first installed the Lenovo Thunderbold Software with their driver) I booted into Linux Mint. I didn't change the BIOS setting to Assistang Mode. Everthing is working like a charm.

Thank you for your suggestions. I tried the update and it didn't correct the issue. After some more trial and error, I found that my issue was caused by the Lenovo external monitor audio device: LEN LT2323pwA.  I disabled the device in the Playback Devices tab after right clicking the speaker icon in the Notification Area of the Windows Taskbar. Once the device was disabled, my laptop speakers work again.

Weve been having this problem with several to many of our T480s with the "pro" dock. USB keyboards specifically are extremely problematic. we have run every single update available, made the bios changes, nothing seems to stick. The problem seems worst if the machine is removed from the dock and re-docked hot. 

 

We never had this problem with the previous iterations of the pro dock. Very frustrating and disappointing.

AHHH, experiencing this issue now and glad I am not the only one.  I was going crazy the other day.  I was using a wireless keyboard and mouse so kept thinking it was batteries or something!  Then tried wired K&M and nothing.  Both/all worked when plugged directly into my T480, but the dock, no way.  Display and ethernet ports worked fine.  Tried updating everything and trying the same, but no go.

 

Think I am just going to send the dock back in.  Of course the day after I throw the box away...

In my experience, we've swapped multiple docks out, and the problem persists. I'm beginning to think the problem is with the laptops themselves.

Well...I am currently typing from my wireless keyboard with the dongle plugged INTO THE DOCK AND ITS WORKING!  I just ran updates for my system for about 45 mins.  After multiple updates, reboots, and completion, it works again!!  I used the Lenovo System update program from the supprt section of this website.

Nice! We could get ours to work, for about a half hour. Then they stopped. or if you undocked, it wouldn't work. We've had enough, it's time for Lenovo to fix this.

It looks like this isn’t just problem of one dock type. It looks like this problem occurs across multiple types of ThinkPad Thunderbolt docks: Pro Dock,USB-C with USB-A HYBRID DOCK, Basic Dock and laptops as well: T480, T480s, T580.
