The user-process loads the input params from the endpoint descriptor. The u16 is libusb_transfer_type+1. | |||
The u32s are: '''bEndpointAddress & LIBUSB_ENDPOINT_ADDRESS_MASK''', '''endpoint_dir''', '''unk''', and '''wMaxPacketSize'''. Where '''endpoint_dir''' is 0x1 for LIBUSB_ENDPOINT_OUT, and 0x2 for LIBSB_ENDPOINT_IN. | |||
HID-sysmodule passes hard-coded value 0x1 for '''unk'''. | |||
