Re: SetReport of IOHDDeviceInterface fails to fire the 1st time



You need to look at the bus. Is the HID report going out on the bus on the first try? Perhaps it's just a feature of the drawer or you are not setting up the correct communication to it and the act of sending the first HID report makes it work. Or, somehow, your first report is not going out. For that reason, a bus trace would be appropriate here.
