The user-process loads the input params from the endpoint descriptor. The u16 is libusb_transfer_type+1.
The user-process loads the input params from the endpoint descriptor. The u16 is libusb_transfer_type+1. However, audio-sysmodule passes hard-coded values for wMaxPacketSize, including 0.
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'''.
HID-sysmodule passes hard-coded value 0x1 for '''unk''', varies for other sysmodules.
