Hi, I have a HP EliteBook Revolve 810 (which is a hybrid laptop/tablet) with the HP active pen that goes with it. I have installed fedora 20 (kernel 3.15.6-200.fc20.x86_64) on this, and the pen does not work out of the box. Playing with evtest, it appears that the kernel reports the X coordinate in ABS_X and in ABS_Y, while the Y coordinate goes into ABS_Z and ABS_RX; here are a few lines of output: Event: time 1406153996.865044, -------------- SYN_REPORT ------------ Event: time 1406153996.873047, type 3 (EV_ABS), code 0 (ABS_X), value 1087 Event: time 1406153996.873047, type 3 (EV_ABS), code 1 (ABS_Y), value 1087 Event: time 1406153996.873047, type 3 (EV_ABS), code 2 (ABS_Z), value 1599 Event: time 1406153996.873047, type 3 (EV_ABS), code 3 (ABS_RX), value 1599 Of course, XOrg's evdev driver is confused and the pointer is stuck on the diagonal X=Y. I guess this hardware needs a new quirk to usbhid, unless there is already a way to correct it ? Here is the content of /sys/class/input/event8/device/uevent: PRODUCT=3/3eb/840b/111 NAME="Atmel Atmel maXTouch Digitizer Pen" PHYS="usb-0000:00:1a.0-1.1/input0" UNIQ="" PROP=0 EV=1b KEY=c01 1 0 0 0 0 ABS=100000f MSC=10 MODALIAS=input:b0003v03EBp840Be0111- e0,1,3,4,k100,140,14A,14B,ra0,1,2,3,18,m4,lsfw I hope I gave enough information on this.
