Description grants 2008-09-02 23:00:43 UTC 
Description of problem:
udevinfo shows correct information but when tablet is connected it does not propergate a KERNEL=="event*" type event to udev.


Version-Release number of selected component (if applicable):
5.2 x86_64 
kernel-2.6.18-92.1.6.el5
linuxwacom-0.7.4.3-2.el5

How reproducible:
always

Steps to Reproduce:
1. Install 64bit version 5.2
2. Plug in wacom Intuos 3 tablet
3. /dev/input/wacom does not get created
  
Actual results:
input and event devices get created under /dev/input only

Expected results:
wacom device/link should be created in /dev/input

Additional info:
-----------------------
 udevinfo -a -p /sys/class/input/event3

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Comment 1 Aristeu Rozanski 2008-09-03 17:11:30 UTC 
this is fixed on the next package version:
http://people.redhat.com/arozansk/wacom_rhel5/linuxwacom-0.7.8.3-3.el5.src.rpm
please give it a try and let me know how it goes. there're binary versions of
this package on that URL too.
Comment 2 grants 2008-09-04 00:13:30 UTC 
yep that seems to work. Thanks for that.
Comment 3 Aristeu Rozanski 2008-09-04 14:18:26 UTC 
Ok, I'll close this bug. If you have further problems, please feel free to reopen.
