USB Composite Device Can't Suspend

Hi All:
Our device is an USB Composite Deivice which inludes USB Video and USB
Audio function. And when the OS in-box UVC driver and UAC driver loaded, the
device can work correctly.
but for suspend function, we found some exceptons:
(1) Before the usb composite device enter suspend, then disable and enable
USB Audio device, the USB Composite device can enter into suspend again;
(2) But if disable and enable USB Audio device after the USB Composite
Device enter into suspend, the USB Composite device can't enter into suspend
any more.

I can't explain why.
Whether there is some bug about the Suspend function about UAC about the
Win7 7600 inbox UAC driver ?
