Hello,
I'm using FreeBSD 10.1 and FreeBSD use webcamd witch contain linux
wacom driver to provide wacom tablets support. More info here:
http://www.selasky.org/hans_petter/video4bsd/ or
http://www.freshports.org/multimedia/webcamd/
I've got latest version of webcamd and Wacom device CTH680, but
device isn't working correct.
Have you tried the device with Linux instead of FreeBSD? If it works in
Linux that means that the port of linux drivers to BSD is to blame and
you need to contact its authors, otherwise we need to adjust wacom
driver in kernel for this device.
Thanks.
Hello, Dmitry.
I've tried tablet in Ubuntu 14.04.1. All functions that work in Windows
7 (in Krita) work under Ubuntu's Krita.
Thank you for your attention.
Hi,
The problem appears to be that webcamd launches two instances for each
interface, so the shared data is not the same like with Linux. Actually
the shared data is NULL.
I think however it would be clever that the Linux Wacom code would check
"wacom->shared->touch_input" for NULL before using it, because it is not
always set. This can be an easy way to crash the kernel when plugging a
USB devices.
drivers/hid/wacom_wac.c:1395
and some more places.
