Bug ID: 202141
Summary: Alps Touchpad AUI1659 not detected as i2c_hid
Product: ACPI
Version: 2.5
Kernel Version: 4.19.13
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Config-Tables
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Everything my kernel is telling me about my touchpad is the following:
[ 9.086767] i2c i2c-14: adapter [Synopsys DesignWare I2C adapter] registered
[ 9.087140] i2c i2c-14: client [AUI1659:00] registered with bus id
i2c-AUI1659:00
i2c_hid does not even try to register with the device.
The machine is a Lenovo V130-15IGM and the ACPI dsl might well be broken, as
PNP0C50 is not even inside the DSL I extracted from the machine.
On Windows the machine is using the following device:
HID\AUI1659&COL01\5&6951D2C&1&0000
But even there the Touchpad started working only after installing the driver
provided by Lenovo.
