[Kde-hardware-devel] Re: udisks ignores blank media by default?

[Jacopo De Simoi]

After some investigation I found out that the issue is given by the following check in isDeviceBlacklisted():


    return property("DevicePresentationHide").toBool() || property("DevicePresentationNopolicy").toBool() ||
            property("DeviceMountPaths").toStringList().contains("/boot") ||
            property("IdLabel").toString() == "System Reserved" ||
            property("IdUsage").toString().isEmpty();

Apparently IdUsage is empty for a blank cd, so this blacklisting rule is a bit too strict.
