T480+TB3 dock gen2 usb keyboard doesn't work after resuming from sleep

So I just got a brand new Lenovo Thunderbolt3 Dock Gen2 to use with my lovely T480.

 

The dock works ok but I have a big problem everytime I put my laptop to sleep at the end of the day. In the next day when I wake my machine (by pressing the power button on the Gen2 dock) my system wakes up fine but my external keyboard doesn't work.

I have to reboot my laptop to get the keyboard working again. Anyone have dealt with the same problem with Lenovos docks? All drivers and firmwares are installed from Lenovos site and the Thunderbolt3 software (the older app not the new UWP) sees the dock fine.

 

Tried to unplug and plug back the USB keyboard but still it doesn't recognize or work.

Tested some more. It seems once the laptop goes to sleep, all of the docks USB ports stop working. Tried to plug the keyboard to other usb-a ports on the dock and none of them make the keyboard to wake up.

 

Only way to get the ports on the dock working is a reboot of the laptop.
