After BIOS update this AM, Dell wireless kb/mouse KM636 stopped working plugged into dock.   Works fine when plugged in direct.  Was working fine before.  I will wait before reverting back to see what support does so I can test.

Same problem here, I'm flashing back 1.6.3.

thanks for feedback. Downgraded to 1.6.3 and the problems seemed to go away, even though downgrade was unsuccessful (according to the messages)

@Dell-Alan D:

I'm running Ubuntu "Budgie" 18.10 alone on my XPS 13.

Actually I was having issues with all the USB devices that were connected to the TB16 (mouse, keyboard, USB headset). The mouse & keyboard would just stop working while I'd be having constant disconnects while using the headset (with constant kernel errors being shown).

Sorry, I cannot test it anymore since I've gone back to 1.6.3 (as this is my daily working unit). Everything works just fine now.

BTW I've seen 1.7.3 download has been removed.

Hi @VasylK / @vpont 

Thanks for advising. Can you both help me with more details about your setups so I can investigate this further please

a) Is this only present on Ubuntu 18.10 or does it also occur on other revisions?
b) What model of keyboard are you connecting to the docking station?
c) If you connect the external keyboard directly to the system, do you still have the same problem with external keyboard functionality?
d) Do either of you run Windows systems and can confirm if the issue is also present on that?

I run only Ubuntu 18.10 on this laptop

> b) What model of keyboard are you connecting to the docking station?

Quite plain classic HP keyboard KU-0316 (USB cable), Mouse Logitech M510

> c) If you connect the external keyboard directly to the system, do you still have the same problem with external keyboard functionality?

I cannot test it anymore - downgraded to BIOS 1.6.3

> d) Do either of you run Windows systems and can confirm if the issue is also present on that?

No Windows :)

@vpont / @VasylK 

Thanks for the prompt replies. As BIOS 1.7.3 has been removed from the driver and downloads site, it's more than likely due to issues found in testing.

With regards to Ubuntu, Canonical hasn't yet certified Ubuntu 18.10 on the 9370. At present, issues with the BIOS update aside, that flavour of Ubuntu isn't yet supported.

Your options are to return to 1.6.3 BIOS revision or run Ubuntu 18.01 in order for us to support the system.

@ Dell- Allen D: I have the same exact problem with Windows 10 pro 64 bit.  I already posted about this a couple of days ago.  See my post here: https://www.dell.com/community/XPS/XPS-13-9370-BIOS-1-7-3-Upgrade-Causes-TB16-Dock-Issues/m-p/7196542#M24148
