[Gimp-user] strange behaviour of the input devices dialogue

[Ulrich Lauther <ulrich lauther t-online de>]

Hi,

I am using gimp  2.8.14 under Ubunto with a HUION H610PRO graphics tablet.

The good news: it works.
However, when I open the input devices dialogue, and select 
"HUION Pen Tablet Pen", this button is highlighted as expected;
but hitting the save button results in an error beep and the
dialogue is not closed as expected.
Any idea what goes wrong or what I am doing wrongly?

Thanks,
