Plextor Premium - nothing active in Plextor tab

Hello.
I have Plextor CD-R Premium device. As far as I read it should be supported by your software. But when i run QPxTool all controls in Plextor tab are inactive. This is what I get from terminal:

This all happens on 0.6.0.9 version on Gentoo.
Thx for any help

qpxtool needs root privilegs. (same with pxcontrol).

# chmod u+s /usr/local/bin/qpxtool
 

Probably you have to adapt the path.

There is already an ebuild for 0.6.1rc2 available, which is setting the permissions automaticly:
