USB Drivers unstable with Lenovo Yoga 3 Core M machine

This remains an annoying problem. Is there no one from DisplayLink who monitors this forum who might like to help make their drivers work with the next generation of Intel processors?

This does not sound like a driver problem, but something unstable on the USB bus. When the problem occurs does everything disconnect from the USB bus or is it just the DisplayLink adapters? Does the problem still occur if you connect directly to the Yoga?

Also try connecting the hub using a USB 2.0 cable to see if it is a problem with USB 3.0. This will help diagnose where the USB instability is.

As far as I can tell, because all the displays are flickering, the USB 2.0 devices (mouse and keyboard) continue to function during the problem times. I do not understand the question "does the problem still occur if you connect directly to the Yoga"? If the question is what happens when I connect a single external display to the USB 3.0 port, I have not tried this and cannot afford to operate in this fashion for hours to diagnose a highly intermittent problem. As for connecting with a USB 2.0 cable, that cable cannot drive three displays, so I am not sure why I would try that.

This problem is not fixed with the latest DisplayLink software, and continues to be an annoyance. It may be more of a Lenovo problem, but it's still a problem I can't seem to fix.
