Long story short. Win 10 free upgrade was available on pendo pad. After upgrade touch screen was messed up, touch left and it would show right and scroll up would show down.

Device and drivers for Windows 10. Didn't detect the audio or touch device either and windows. KMDF HID Minidriver for Touch I2C Device'. DriverHive Database Details for KMDF HID Minidriver for Touch I2C Device Driver.

This tablet has just one micro USB port and to revert back I had to have the power connected but couldn't select the rollback option. A reset made it worse as it removed windows. Hp Cd Dvd Driver Windows 10. old and the recovery partition could not give me much as the reset replaced it with win 10 files. A few weeks, calls to MS tech support and manufacturer gave little or no result. Qualcomm Atheros Ar9485 Driver Windows 10 Asus. Manufacturer says return the device if under warranty which it isn't.

Device manufacturers website is hopeless (sileadinc) is in some Asian language cant really get anything out of it. MS tech support told me there is no way of installing win 8.1 as the ISO from media creation tool is not with 'bing' and it refused the OEM key which I had. I managed to find the OEM ISO and installed it and activated without MS help but the touch screen refuses to work.

The device driver doesn't show the device either. My audio device also having the same problem. There are 5 Intel I2C and 2 UART in the device manager list with yellow triangle and a '!' Update driver option says up to date but properties show error code 37. I don't want to use the USB hub al the time, it defeats the purpose of having a tablet.
