Trackpad not working for legacy protocols?
#1
I've been experimenting with the mainlain kernel that tsys has been working on. One thing I picked up on is that the trackpad goes pretty crazy (point movement is completely wrong and keeps jumping the mouse cursor to top left) unless CONFIG_HID_MULTITOUCH is set in the kernel config.

When CONFIG_HID_MULTITOUCH isn't set the kernel should be falling back to legacy (mouse) protocols. I haven't looked very deeply at this point I am suspicious that the trackpad firmware simply isn't implementing the fallback protocols properly... so I wanted to check if this is a known bug (or a plausible theory)?
