Touchscreen stops working if USB device is connected [Yoga 13]

2014-11-11, 12:00 PM

First year, my Yoga's touchscreen was always working correctly, regardless of connected USB devices.

 

Since some time, if I connect a device into USB 2.0 port, touchscreen gets immediately disabled, no more responding to any touch. In Device Manager, it is not showing any errors. I found a workaround that in Device Manager (HID Devices branch), touchscreen must be set Disabled, then Enabled and then it comes back online. But I know this action was never needed before.

 

Do you have any solution for this?

 

I think it began happening around the time when I started to use Yoga with barcode scanner Heron D-130. But the problem is now happening regadless of USB device, even with devices which were not impacting the touchscreen before. Perhaps not barcode scanner, but some Windows update caused this. Do you have any solution for this so touchscreen will keep working after another USB 2.0 device is connected?

At the moment it looks like disabling power saving feature at touchscreen HID device (in Device Manager) solves the issue. Touchscreen is kept enabled even if I connect other USB devices.
