[Linuxwacom-discuss] wacdump problem: ParseData 22 Invalid argument

[Michael F. <mic...@gm...>]

Hi,

I am trying to get my Graphire2 working on a Gentoo box with kernel 2.6.4 and 2.6.3 with linuxwacom from cvs, both with the stock kernel module and linuxwacom wacom.ko . It seems that the driver is loaded correctly, dmesg gives (with stock module):

usb 2-2: new low speed USB device using address 2
hid: probe of 2-2:1.0 failed with error -5
input: WACOM ET-0405A-UV2.0-3 on usb-0000:00:1d.1-2
drivers/usb/core/usb.c: registered new driver wacom
drivers/usb/input/wacom.c: v1.30:USB Wacom Graphire and Wacom Intuos tablet driver
devfs_mk_dev: could not append to parent for input/event0

and 
# usbmodules --device /proc/bus/usb/002/002
hid
usbmouse
wacom
 
This looks quite correct to me. But wacdump gives the following output,
after I move the pen over the tablet:
# /usr/local/bin/wacdump /dev/input/event2
wacdump v0.5.2

MODEL=Wacom Graphire2 4x5               ROM=2.0-3

ParseData:         22 Invalid argument                         (35)


It seems to react to my movements in some way, the hexdump changes when the pen moves. But there seems to be an error when wacdump parses the
raw data, because buttons etc dont work as they should, and hexdump
and RELWHEEL are the only values that change.

Has someone an idea what could be the problem here? I am a bit frustrated after 2 days without any result ...
thanks in advance,

- Michael.


BTW: I also tried using it with X (wacom_drv from linuxwacom, XFree 4.3.99.902), but when using the wacom driver the cursor doesnt even move, I only get some "wacom: rel event recv'd" in the logfile. Using /dev/psaux (a repeater in 2.6?) and protocol ps/2
I can move the cursor with the pen, but only in y-direction, and the
cursor immediately jumps to the left screen border. But I think
I have to get wacdump working first...
