> wsp IDS should be blacklisted in usbhid quirk table

hmm right now quirks can only exclude a whole device, not just an interface.
That would prevent usbhid from attaching to the keyboard interface.

> Try updated patch.

Looks like it didn't help.

hmm does the usb_fifo_alloc_buffer stuff matter?

(also looks like closing moused would always kill evdev events - 
wsp_fifo_stop_read doesn't check for evdev)

> Some debug info is required

Oops, actually, there are events on evemu as soon as moused is up. They're just
not accepted by libinput.

Looks like the missing thing is the initial MT_SLOT 0 (for the first events,
before any extra fingers arrive).
