Both collections get merged and, because the first one defines X and Y, the movemenent events reported by the trackpoint collection are ignored. Set the MT_CLS_WIN_8_FORCE_MULTI_INPUT class for this device to be able to receive its reports. This fix is similar to/based on commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for some devices").
