Severe screen flashing on 7.4M0

Hi,

The support files tell us that there are usb connection errors which will cause the ethernet connection to drop.

Can you check if you have the latest hub firmware programmed?

Open up device manager, open up Universal Serial Bus controllers and right click on the entry called “Generic SuperSpeed USB Hub”.
Select “Properties”, select “Details”, change “Property” to “Hardware Ids” and the REV_xxxx value will tell you what version of firmware is programmed on the hub.

Let me know what revision is reported.

I'd also suggest trying another USB cable & other USB ports.

It's also worth trying the "System Compatibility Check" option in the DisplayLink debug tool to see if anything is flagged up.

Thanks,
James
