From b4dbde9da8ece42bbe4c70c26bac3b28dd6a3ddb Mon Sep 17 00:00:00 2001 From: Alan Ott Date: Tue, 18 Jan 2011 03:04:39 -0500 Subject: HID: Add Support for Setting and Getting Feature Reports from hidraw Per the HID Specification, Feature reports must be sent and received on the Configuration endpoint (EP 0) through the Set_Report/Get_Report interfaces. This patch adds two ioctls to hidraw to set and get feature reports to and from the device. Modifications were made to hidraw and usbhid. New hidraw ioctls: HIDIOCSFEATURE - Perform a Set_Report transfer of a Feature report. HIDIOCGFEATURE - Perform a Get_Report transfer of a Feature report.
