Carbon X1 - different problems on USB 2.0 & 3.0 since windows 8.1 OS update last wk

Thanks James.

I did but same somewhat unpredictable issue. After reboot 2.0 works for 30 minutes before monitors are dropped (device mgr screen shot uploaded).

Switching to 3.0 hub have to use a wired mouse in the 2.0 hub - my scanner & disk drive peripherals drop and reload intermittently - monitors may drop then have to reboot and start all over.

Again, the only change i recall was the Windows 8.1 OS update over a week ago and it's been problems ever since.

Would the alpha version of the Displaylink software be worth trying?
