Forget about HID over I2C on Windows 7, since native support was introduced in Windows 8. A friend of mine also tried to get the elan touchpad to work with no avail. If you don’t want to migrate to Windows 10, then I recommend that you install Windows 8.1. It still has support up to Jan 2023 (Oct 2023 if you use Embedded 8.1 Industry Pro/Enterprise).

where do u find the i2c driver for windows 8.1?


Depends if your laptop’s mobo is based on the AMD chipset or Intel’s. Post your laptop model
