I'm experiencing a problem with my new UFX.
The control leds for TRS and phantom power stay on in ch. 9-12. I can't switch on or off the TRS nor the phantom power.
Update of firmware/drivers doesn't help.
I tried it on an iMac 10,1 Snow leoprad 10.6.6. and under Windows Vista Quad Core.
The problem is the same via USB and Firewire.

Sometimes after a while I get a signal on one of the channels, it buzzes and all of a sudden only the TRS for ch. 9 is on, the leds for phantom power and TRS of the other channels are out and I can then switch on and off TRS/phantom power.

Any ideas/help?
