Comment 33 for bug 1923515

Yes, I've been working on installing Windows, and also speaking with Dell, whose support techs say a replacement touchpad should have been the exact same model as the original (except not with a hardware defect). I wanted to make sure they'd support the laptop, which came with Windows, as well as see what device Windows detects.

Interestingly, Windows 10 has basically the same issue as Linux! I sees a device called "I2C HID device" that has problems, and in that device's status are the messages "The device cannot start (Code 10)" and "A request for the HID descriptor failed." There's also a pointing device called "PS/2 compatible Mouse" that is ... definitely not a PS/2 mouse.

So, I think Windows agrees with Linux and this might not be a kernel issue after all. No amount of Dell Windows driver updates or Windows updates resolves it, and a Dell tech spent a long time remote controlling and testing with me. It looks like Dell replaced a piece of bad touchpad hardware that had good firmware, with a piece of good touchpad hardware that had bad firmware. I'm getting a *second* replacement touchpad in about a week.

I can update this bug after the new one is installed and confirmed working, and I reinstall Linux.
