Strange, because the driver seems to be loaded. Have you recompiled the
Plustek backend ?
Have you called the make install in the sane source directory ?
It looks like scanimage uses an old backend !

You're right this is not the problem. This occurs for the new GCC 2.95
and didn't
when using the older GCC 2.72 (I use !)
But I will remove the warnings next time.

This should be done by MakeKernel in backend/plustek_driver when
calling make load !
