[RPC, ubuntu] basic_tf_stub example

[poyupaulchen]

-Platform: apollo4p -os : ubuntu I tried the basic_tf_stub example on ubuntu for checking whether PRC is working. I followed the instruction // #define RPC_ENABLED in basic_tf_stub.cc and uncomment it and compile it. It seems not working.

1. NS_USB1_PRESENT below seems not existing. https://github.com/AmbiqAI/neuralSPOT/blob/696a2cd9a8262f40676695650f1bbdbb8b61da69/examples/basic_tf_stub/src/basic_tf_stub.cc#L15-L17
2. After I did make deploy, I can not find the ttyACM0 or ttyACM1. Usually, I can find it as below

   poyupaulchen@paul:~/Documents/esc/evb$ ls -la /dev/serial/by-id
   total 0
   drwxr-xr-x 2 root root 80 Feb 28 17:26 .
   drwxr-xr-x 4 root root 80 Feb 28 16:42 ..
   lrwxrwxrwx 1 root root 13 Feb 28 16:42 usb-SEGGER_J-Link_000900030197-if00 -> ../../ttyACM0
   lrwxrwxrwx 1 root root 13 Feb 28 17:26 usb-TinyUSB_TinyUSB_Device_123456-if00 -> ../../ttyACM1

Update: It works now after I rewrite from https://github.com/AmbiqAI/neuralSPOT/blob/696a2cd9a8262f40676695650f1bbdbb8b61da69/examples/basic_tf_stub/src/basic_tf_stub.cc#L15-L17
