RE: [PATCH 1/2] Alps HID I2C T4 device support

Show all headers | View raw

Hi, Nikolaus,

If you have a time, please try below debug method.

Download below file, copy it to your system and unpack.
https://www.filesanywhere.com/fs/v.aspx?v=8b716a8e5b6773baa799

Procedure ex:
#cd Desktop/LinuxModDebug
#sudo chmod 755 linux_kr_rebuild_tool_hid.sh
#sudo ./linux_kr_rebuild_tool_hid.sh /init linux-4.10.tar.gz
#sudo ./linux_kr_rebuild_tool_hid.sh /build DebugSrc

After that Touchpad all features should work.
If Touchpad does not work, something error appears on dmesg.

Best Regards,
Masaki Ota

Hi Masaki,

Well, I'd be pleasently surprised if every bug always came together with an associated error message :-). No matter if there's a dmesg entry or not, at the moment this patch will make life much worse for at least some EliteBook owners.

Is there anything I can do to help you debug this?

Best,
-Nikolaus
