xorg.0.log with dissapearing/reappearing wacom devices

Just found out something strange:

Steps to reproduce: kernel-
1) turn on computer+login: wacom devices are ok
2) suspend to ram then wake-up: Wacom devices are gone.
3) restart Xorg : wacoms are still not found
4) re-suspend then wake up: wacom devices are detected.
5) Suspend+wake-up again: Wacoms are gone again...

the Xorg.0.log following these step is attached: Xorg.0.log-

dmesg with several suspend/resume events.

dmesg with several suspend/resume events. 
usb 7-2, where wacoms are apparently connected, get properly detected only every second wake-up.

Comment 3 Bug Zapper 2010-11-03 14:17:58 UTC
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
