D6000 - Supports only two displays when connected to USB type C with alternate mode.

[Nethval]

I bought D6000 recently and out of the box it worked correctly (two monitors over USB A and three monitors over USB C). I'm using it with two laptops (Asus Zenbook Pro Duo and Lenovo P50, both support alternate mode). Had no problems with first one but on P50 i encountered issue with mouse and keyboard lagging. This made me to update firmware on D6000 to:

D6000 controller: 0019
TI PD controller: 01020109
PR converter: 0B7D

GL HUB1: 8816
GL HUB2: 8817

This update broke three monitor support on the Asus Zenbook Pro Duo and right now only two monitors works on both USB A and USB C. Issue with mouse and keyboard still exists on P50. I used second D6000 from my work and it exibits the same issues. Is there anything that i can do? Everything is updated to the latest. I'd like to downgrade firmware but i don't see a possibility. I had no single problem with D3100 and i'm pretty disappointed with this implementation. It was pretty obvious that this will cause nothing but issues compared to displaylink only outputs.

Hello,

Thank you for contacting us on the forum.

Could you please gather the log files by following the third link in my signature?
I will need them to run the proper analysis. May you please confirm that right now the two working monitors are connected by DP and the one not working is the HDMI? Is there a possibility for you to plug in the present not working third monitor into a DP port to verify if it will work there?

Thank you for your actions,

Best regards,
Jakub
