20" ADC (acrylic) cinema shows up but I can't control brightness on it

[Joseph Cranmer]

Hi, I have both a 23" and a 20" adc cinema display (acrylic) and the 23" works terrific with Brightness Controller, thank you! However I've noticed even with the latest 1.4.4 the 20" is detected, but doesn't respond to changes in brightness.

Instead, brightness controller lags for about 10 seconds attempting to do things, generally resulting in no change. Both are connected to my computer through Apple DVI to ADC adapters, and I did try switching the adapters to make sure that wasn't the problem, but the 20" still won't work with it. I also tried using the 20" by itself and it still wasn't able to adjust brightness that way.

If there's any way I could help, please let me know. I'd be happy to try :)

Thanks!

Here's the info from the HID tool (just used the xml tool to make it easier to read :)) :
