Hi John,



Welcome to Microsoft Community and thank you for posting your query.



Based on your description, the issue seems like HooToo USB port driver is outdated. Let’s try simple steps and check if this help.



I recommend you to update the HooToo USB port driver and check if this helps. Follow the below steps.

• 
  Press Windows key + X and click on
  Device manager.
  
• 
  Click on Universal Serial Bus to expand and right click on the port device and click on
  Update.
  

If the issue still persist, I suggest you to go to the USB manufacturer website and install the driver for Windows 10. If the available USB driver is not for Windows 10, try installing the driver in compatibly mode and check.

Serial port data streaming

Full project details:

Transmit 3-axis acceleration data via wireless RF communications.

A digital accelerometer sends data to a XBee RF module, the data is sent via serial commands with a Basic Stamp 2 micro-controller. The XBee transmits the data to a receiver called XStick which is a USB device that appears as a serial port.

Right now the USB XStick has an open terminal to stream and view the data, but it's not user friendly and other than watching the data come in it doesn't do much else.

I'd like to use this streaming serial port data to update a graph or alternative plot. I have no idea how to do this.

Otherwise, I'd like to have a user friendly way of exporting the data to Excel for easy processing. Alternatively, a .csv file would be friendly for MatLab(if anyone wants to help *Smile ).

So there, theres some more details. Thanks for reading.
