What type of HID driver?
Input Device.
You shouldn't need to do that, the HID layer will give you the proper
messages to you, right?
In order to send a SetFeature command you need to go over the report list
the device declared at enumeration time.
Some of the Set/Get Feature trigger a response from the device, and i
need to get
the answer using the HID mechanism the question is How?
Your first suggestion is used in a driver which not rely on the HID core.
Thanks
