What do you mean by "Function 0019"? What does it have to do with a function and what is the 0019? > As near as I can tell > from searching on Google, this is not a "standard" function.

SetupPacket bytes: 00 81 80 00 00 00 00 00, DIR = Host > to device. As far as I can tell, that is an invalid setup packet. bRequestType = 0x00 means OUT, Standard type, and device recipient. But 0x81 is not a standard bRequest value. If you wanted it to be a vendor-specific type with an endpoint recipient then bRequestType would have to be 0x42. > How do I know this is important to the device, because this > packet is what causes the device to return it's data.

What is a "custom function type"? It sounded like you simply want to send a particular packet. You can do that with usb_control_msg() or the equivalent. > Can someone offer a hint (if one exists) for sending a custom function > code to a device. Before you mentioned a custom function _type_; now you mention a custom function _code_. Which do you want? And what is it?
