Heya, I'm pretty certain that's already been discussed, but can't seem to find the thread in question, or whether somebody sent patches for the issue. The problem I see is that the input device is advertised really early in its creation, and seems to be missing information when udev (and layers above it in the stack) probes it. Using Linux 3.1.0 rc6 Turning on a Bluetooth Wacom tablet I see the following udev events: UDEV [1890.604848] add /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/bluetooth/hci0/hci0:42/input10 (input) UDEV_LOG=3 ACTION=add DEVPATH=/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/bluetooth/hci0/hci0:42/input10 SUBSYSTEM=input PRODUCT=5/56a/81/100 NAME="WACOM Pen Tablet" PHYS="00:13:EF:F1:42:B7" UNIQ="00:13:C2:03:3D:D6" PROP=0 EV=17 KEY=70000 0 0 0 0 REL=103 MSC=10 MODALIAS=input:b0005v056Ap0081e0100-e0,1,2,4,k110,111,112,r0,1,8,am4,lsfw SEQNUM=2391 ID_INPUT=1 ID_INPUT_MOUSE=1 ID_PATH=pci-0000:00:1a.0-usb-0:1.1:1.0 ID_PATH_TAG=pci-0000_00_1a_0-usb-0_1_1_1_0 ID_FOR_SEAT=input-pci-0000_00_1a_0-usb-0_1_1_1_0 TAGS=:seat: If I do a udev database dump I see: P: /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/bluetooth/hci0/hci0:42/input10 E: UDEV_LOG=3 E: DEVPATH=/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/bluetooth/hci0/hci0:42/input10 E: PRODUCT=5/56a/81/100 E: NAME="WACOM Pen Tablet" E: PHYS="00:13:EF:F1:42:B7" E: UNIQ="00:13:C2:03:3D:D6" E: PROP=0 E: EV=1f E: KEY=1c63 70003 0 0 0 0 E: REL=103 E: ABS=3000003 E: MSC=11 E: MODALIAS=input:b0005v056Ap0081e0100-e0,1,2,3,4,k100,101,110,111,112,140,141,145,146,14A,14B,14C,r0,1,8,a0,1,18,19,m0,4,lsfw E: SUBSYSTEM=input E: ID_INPUT=1 E: ID_INPUT_MOUSE=1 E: ID_PATH=pci-0000:00:1a.0-usb-0:1.1:1.0 E: ID_PATH_TAG=pci-0000_00_1a_0-usb-0_1_1_1_0 E: ID_FOR_SEAT=input-pci-0000_00_1a_0-usb-0_1_1_1_0 E: TAGS=:seat: See the different KEY= value, and the presence of the ABS= key. If the tablet was probed at this point it would have the ID_INPUT_TABLET=1 property (as running input_id by hand shows).
