Issues with U46 series and OS X 10.10 - Yosemite
In order to make sure that an interface of our U46 series (U46DJ,
U46 SE and U46
XL) works under OS X 10.10 (Yosemite), it is important that you are using
our control panel with Version 1.3 or higher. If any previous or older version
is installed, the hardware cannot be controlled properly.
