Touchscreen not recognised

[Harleybiker]

Due to the hinge support breaking behind the screen I have had to replace both the hinges and the lid cover containing the screen. Prior to this change, the touch screen was working perfectly. On rebuilding the lid housing the screen everything worked fine other than the touch screen. I can confirm all connectors are attached to the motherboard as they should be.

In regard to hardware, I have replaced the digitizer which made no difference.

On the software side, I have checked settings - system - about - pen and touch where it states 'No Pen or Touch input is available for this display'.

In device manager under Universal Bus Controllers,  one controller states 'UnknownUSB Device (Device Descriptor Request Failed). On opening properties for this device the Device Status switches between 2 messages, they are:

1.Windows has stopped this device because it has reported problems (code 43) A request for the USB device descriptor failed.

and

2. Currently, this hardware device is not connected to the computer (code 45). To fix this problem, reconnect the hardware device to the computer. A request for the USB device descriptor failed.

To clarify there is no listing for the touch screen under Human Interface Devices even with 'show hidden devices' selected. I have also replaced the original hard drive with another which only contained a freshly installed version of Windows 10. This displayed exactly the same results in device manager etc so I think it would be safe to eliminate registry errors.

Does anybody have any suggestions as to how I might proceed before making the investment of replacing the touch screen itself? Any feedback would be gratefully received.
