All commands are wrappers for usb:ds requests with USB configured as:
VID: 0x057E (Nintendo Co., Ltd) PID: 0x3000 bcdDevice: 0x0100 (1.00) Manufacturer: "Nintendo" Product: "NintendoSdkDebugger" SerialNumber: "SerialNumber"
SystemInitializer only uses cmd1..cmd3.
InitUsbTransferPipeFsFile
Takes an unknown u32 (ID?) and configures a transfer pipe over usb:ds for file access mode.
FsFile_Exists
Takes an input path string (type-0x9 buffer), returns 8-bytes for the output u8 flag.
Checks whether the specified file exists.
This is "FsFile::Exists" in SystemInitializer.
FsFile_Read
Takes a type-0x6 output buffer and a type-0x9 input string path buffer, and 3 u64s: <same size value from databuf>, unk, <same size value from databuf>. Where unk is probably offset?
Reads data from the specified file.
FsFile_Write
Same as FsFile_Read except the databuf is a type-0x5 input buffer.
Writes data to the specified file.
SystemInitializer also uses this as "FsFile::Create" with all input u64s set to 0.
InitUsbTransferPipeRaw
Takes an unknown u32 (ID?) and configures a transfer pipe over usb:ds for raw access mode.
Raw_Read
Takes a type-0x6 output buffer and 2 u64s: offset and size.
Reads raw data from the device.
Raw_Write
Takes a type-0x5 input buffer and 2 u64s: offset and size.
Writes raw data to the device.
