23" Acrylic ACD Not Detected

[Julien G]

Hi Jens,

I have a 23" acrylic ACD connected as a second monitor to a Radeon HD7700, and Brightness Controller isn't detecting it. Windows 7 picks it up just fine, listing it properly under Devices and Printers. (The USB cable is connected, of course.) Iv'e attached the HID log output.

Any insight? Thanks for being so responsive.
