auto hardware detection not working

[Pascal de Bruijn]

Hi,

I enabled hardware detection in my builds of GNOME Color Manager.
However it's not working, the "Calibrate" button is enabled, no matter
if a colorimeter is attached or not.

Assuming gcm-prefs isn't the problem, I'm guessing this would be a
udev issue? Or better a udev rules issue?

Is anybody willing to give me some pointers on how to debug this issue?

Regards,
