#259 Add support to Intuos PT series to xf86-input-wacom
Hello.
I'm using FreeBSD and I've recently bought this: http://www.wacom.com/en/de/creative/intuos-m device, but find out that device is not supported yet by xf86-input-wacom driver.
FreeBSD ports contain driver version: xf86-input-wacom-0.26.1
Here is some output from device:
ugen1.3: <Intuos PTM="" Wacom="" Co.,Ltd.=""> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (498mA)
bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0000
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0040
idVendor = 0x056a
idProduct = 0x0303
bcdDevice = 0x0100
iManufacturer = 0x0001 <Wacom Co.,Ltd.="">
iProduct = 0x0002 <Intuos PTM="">
iSerialNumber = 0x0000 <no string="">
bNumConfigurations = 0x0001
If you need more info from me, ask.
Thank you.
I haven't tried the driver with FreeBSD, but on Linux at least there is no need for xf86-input-wacom to have explicit support for this tablet. All the necessary information is queried from the kernel device and the internal structures that exist are for compatibility with old kernels that don't provide the necessary interfaces.
Are you sure an input device node is being created for the Intuos by your kernel? A lack of support in the kernel driver is what usually causes tablets to not work on Linux.
Hello, Jason. I find out that device was defined by HAL only after user session restarting. But only touch by fingers are working. Pen is not working.
So, the problem, as you say, not in xf86-input-wacom, but in kernel driver.
Thank you for your time.
Hello again,
I have additional information about the problem I faced. I found out that the FreeBSD has no its own Wacom driver. It uses port webcamd http://www.selasky.org/hans_petter/video4bsd/
This webcamd contains input-wacom Linux driver.
I've compared files from your git repo and from latest sources of webcamd and it's almost similar with your ./3.17/ files. Difference in a few lines in wacom_wac.c and wacom_sys.c. Developer of webcamd tells me that he is using Linux kernel drivers which maintained by linux-input@vger.kernel.org. I've created a report in there mailing-list, but no luck with answer.
So, I took files from your repo (wacom_sys.c, wacom_wac.c, wacom_wac.h, wacom.h) and overwtote files from webcamd, then I reinstall port and here that I have:
I'm starting webcam processes manually to create input devices.
First process creates stylus/eraser device(/dev/input/event0) as I understand. It seems so to me because when I trying to execute: cat /dev/input/event0 the abracadabra appears when I start driving by pen.
Second process creates three devices (event1, event2 and js0) event1 react (when “cat /dev/...”) on fingers moving, event2 and js0 on pushing buttons on tablet.
The first process often crushes. It crushes when I trying to execute “cat /dev/...” everytime. Here is the result of core debugging:
Core was generated by `webcamd'.

I must say that this output is the same irrespective of using files from your repo or from webcamd.
Also, here is some outputs from utilities:

Pressing of buttons works not every time. If I press one button, it works ~ once from three.
In attachment I've put xorg log. As I can see first process crashes after xorg asking it in first time [ 89.832], [ 89.843]. In second time in [ 105.374] first process (event0) has already crushed.
Closing the original issue. Second issue (crash when using the tablet under FreeBSD) should be resolved by the patch at: http://www.spinics.net/lists/linux-input/msg34362.html
