Totally the same issue, do you have any solution?
It seems to be the same problem with all dedede-Board devices. See: Chromebook CX1500CKA Issue with Touchpad and Audio Driver

no, it’s not. It’s a problem with all the GALTIC boards (GALLOP, GALITH, GALNAT).
the issue is that there are two touchpad options which use the same i2c bus/address, so there is no way to know which one is present at boot time. This leads both of them to be marked active, and Windows doesn’t know how to deal with that. I have a workaround but waiting for Google to ok the change on their end before I make it widespead

Hi, I have the similar problem on my Acer Spin 11 (R751T), but it is related to I2C device and to EC sensor hub, as seen below.
Could I ask for help on how to solve this issue?
Many thanks in advance and best regards.

Hello Mr Chromebox,
Could you please help and write how to fix the yellow exclamation marks on the two devices seen below? My device is Acer R751T.
Thank you in advance for your support and best regards.
I’m still not able to DM since I’m not “basic user”, I’ve done the discobot tutorial but couldn’t find any info about how to gain that status

@frosty @chromi I have just added a new function to the Firmware Utility Script, which will allow you to set the touchpad type in SSFC (secondary storage firmware cache) so that it will work properly under Windows. Simply boot Linux, run the script, set the touchpad type using the menu option, then reboot into Windows. LMK if any issues
