Wacom Intuos3 makes system unstable

Recommended Posts

Hi all.

I've Leopard working without any issue on my pc (see hardware spec in signature)

I've installed it with the iAtkos r3 release, cause I'm on an nforce chipset mobo


I've just bought an Intuos3 A5 Tablet.


Here is my problem:


If I plug in the tablet and install the wacom driver, the tablet work flawless, but my network card drops the connection after few minutes and all the system becames "laggish".

If I remove the wacom kext all returns fine.


Anyone has the same issue?

Any advice?


The wacom kext for Leopard are the first release, if I'm not wrong, maybe they have to be improved?


thank you

Perhaps I've solved. ;)


Using console.app I've seen that the problem was with IOHID and not only with network: I was gettin HDI error every time that I moved my usb mouse.

So I've unistalled again Wacom driver unplugged the tablet and rebooted.

After the system has loaded I've plugged in the tablet and unplugged the usb mouse. then rebooted again.

Then I've installed Wacom driver again.


And now all seems fine even if I've to test more accurately.



Hope this help if someone get same issue.

I got again the "drop connection"/"laggish system" issue after about 8 hour the system was running.

Is there a way apart from the app. console to inspect the system to find what causes this issue?

I really can't understand why the wacom tablet can provoke this, It's only a "USB mouse".

I was neither using the pc when it happen this time.


thank you
