edgetpu: USB transfer error while running inference for Posenet model

Platform: aarch64, IMX8 Edge TPU Release: 2.13 Edge TPU Device: USB stick Model used: posenet_mobilenet_v1_075_481_641_quant_decoder_edgetpu.tflite

Having a strange USB transfer error while trying to run a pose estimation inference. Had no problem running the USB stick with some simple object detection, this seems only to occur when trying to implement the pose detection stuff.

F :1133] HandleQueuedBulkIn transfer in failed. Not found: USB transfer error 5 [LibUsbDataInCallback]

Tested several ways to initialize the interpreter and prepare the input but with same result. Right now I’ve used the code available in the /src/cpp folder, just to see if it made any difference;

basic_engine.h/.cc basic_engine_native.h/.cc posenet_decoder.h/.cc posenet_decoder_op.h/.cc error_reporter.h/.cc edgetpu_resource_manager.h/.cc

So basically:

m_engine = new coral::BasicEngine(poseModelPath);

std::vector<uint8_t> input;
formatInput(inputImage, input);

const std::vector<std::vector<float>> &raw_outputs = m_engine->RunInference(input);

The crash happens when Invoke() is called in

EdgeTpuApiStatus BasicEngineNative::RunInference(const uint8_t *const input,
    const size_t in_size,
    float const **const output,
    size_t *const out_size);

Thanks!
