Where are you finding HcDisableSelectiveSuspend (and in what context?) in the first place?

Hi ,
Let me clarify again. I have a composite usb device with modem, virtual serial port etc. For this device i am using usbccgp.sys to enumerate child functions in Win 7. in this scenario i wanted to know if there is any mechanism for disabling selective suspend in certain cases. I am aware that device will not selective suspend if any one of the child function does not request for selective suspend. i have very specific cases where i need to disable selective suspend.

i came across HcDisableSelectiveSuspend while looking out on net,
http://msdn.microsoft.com/en-us/library/ms793220.aspx

So is there any way to disable selective suspend for my device.

That is an XP key. Do you own any of the child stack FDO drivers? If so, just don’t have the driver selective suspend and that will disable USB SS on the rest of the functions

Hi Doron,
Thanks for the reply. Is there any other option either in the inf of composite driver(usbccgp.sys) or in the composite filter driver that we write for changing the enumeration behavior ?

Don’t know of any other method offhand. Why do you want to force USB SS off ?
