无法开启NPU，推理报错

信息如下，
E NPUTransfer: Transfer interface open failed!, ret = -4
E Catch exception when init runtime!
T Traceback (most recent call last):
T   File "rknn/api/rknn_base.py", line 506, in rknn.api.rknn_base.RKNNBase.init_runtime

这个没有办法解决？

你们的demo都没有办法开启npu，我买到一个假的开发板？

我手上的板子跑得好好的，你这个感觉像是通信出了问题。
1.敲一下lsusb命令看看
2.可能npu休眠了？有个命令可以唤醒：npu_powerctrl -r

你可以usb3.0口插个U盘，lsusb看一下能不能认到，排除下是不是usb3.0有问题。

usb3.0可以识别到键盘

重新上电，然后输入lsusb试下，正常300s会进入休眠。

重拔以后lsusb 这样

然后呢？不明白休眠什么意思

程序仍然报错，要做什么操作吗
