WacomOpenTablet: Invalid argument

[Tom_greig]

Hi,

I've been trying to get the touch screen to work on my Fujitsu Lifebook P1610 using the method on http://blogs.fsfe.org/alge/?p=111 but when running the perl script I get the following results


Initializing... (please don't touch the screen)
WacomOpenTablet: Invalid argument
Ready!


The touch screen the continues to not work.
I thing the "Ready!" bit is just a printed out statement and means nothing.

Any ideas about how I could fix this and get the screen working would be appreciated.

Thanks in advance,
Tom.
