在RK3399的平板上面，使用TB-RK 1808S0出现异常

你好！
     我在RK3399的平板上面，使用TB-RK 1808S0，插入USB3.0的口进行NPU计算，运行10分钟后，发现算法运行异常，经过Log分析发现，TB-RK 1808S0 自行断开导致异常。

     请帮忙分析一下，为什么运行一段时间后会自动断开TB-RK 1808S0？
     log的关键字 “NPUTransfer: usb write failed: ret = -4: LIBUSB_ERROR_NO_DEVICE”

是否兼容性问题，还是我这个平板的ROM，需要升级？

有人可以支持吗

确认下计算棒版本号和你api版本是否匹配

版本是匹配的，目前发现把 RKNN_FLAG_ASYNC_MASK 变为 RKNN_FLAG_PRIOR_MEDIUM 就可以了，但是速度会慢1倍
