[Acer c720] No touchpad since last upgrade

Hello,

Since I've last upgraded I've lost support of my touchpad. Touching it has no effect whatsoever. My USB wireless mouse works perfectly.

I've been using the modified kernel "3.15.5-1-chromebook" since the beginning. I tried upgrading this kernel with the aur/linux-chromebook package, but it hangs at some point during the kernel compilation.

At boot time, I now see this error : "usb 1-4: string descriptor 0 malformed (err = -61), defaulting to 0x0409"

When I list /dev/input/by-id, I don't think my touchpad appears, though the webcam and USB wireless mouse do.

Any ideas ?

Thanks !
