Hey guys, the Touchpad of my Acer VN7-571G doesn't work under the upstream mainline Kernel anymore. Im running Ubuntu 15.04. I: Bus=0018 Vendor=06cb Product=2970 Version=0100 N: Name="SYN1B7F:00 06CB:2970 UNKNOWN" P: Phys= S: Sysfs=/devices/pci0000:00/INT3433:00/i2c-0/i2c-SYN1B7F:00/0018:06CB:2970.0001/input/input7 U: Uniq= H: Handlers=mouse0 event7 There were always some errors in dmesg, but the touchpad worked nice. Booting with the new mainline Kernels, it crashes. Here you can find some reports of a self written test for a variety of Kernels: https://www.dropbox.com/sh/fpc809htqzx3hfk/AABDjGPT0I67L-jFqe-8RUSFa?dl=0 The test contains the output of: dmesg | grep i2c dmesg | grep hid xinput On the self compiled kernel 4.2.0-rc3-wl-ath from the ath tree, i reverted the only commit from for-4.2/i2c branch: diff --git a/drivers/hid/i2c-hid/i2c-hid.c b/drivers/hid/i2c-hid/i2c-hid.c index 92d6cdf..0dfb5d1 100644 --- a/drivers/hid/i2c-hid/i2c-hid.c +++ b/drivers/hid/i2c-hid/i2c-hid.c @@ -1019,7 +1019,6 @@ static int i2c_hid_probe(struct i2c_client *client, hid->driver_data = client; hid->ll_driver = &i2c_hid_ll_driver; hid->dev.parent = &client->dev; - ACPI_COMPANION_SET(&hid->dev, ACPI_COMPANION(&client->dev)); hid->bus = BUS_I2C; hid->version = le16_to_cpu(ihid->hdesc.bcdVersion); hid->vendor = le16_to_cpu(ihid->hdesc.wVendorID); But the Touchpad still doesnt work.
