I recently got a brand new Latitude 5320 2-in-1 and it worked fine. After first Windows Updates, my Touchscreen is not working anymore.
Device Manager shows I2C HID Device issues.
Usual steps trying to fix it did not help:
- (Yes, I tried a reboot ) - Checked that Touchscreen is enabled in BIOS - Dell Command update used, all latest updates installed, incl. BIOS - Uninstalled device and re-installed - Windows updates installed - Hardware troubleshooter executed (can't fix the problem)
