On TECI4 and Nanotrack the USB to serial port used is a FTDI device which by windows default has a value of latency timer value of 16. For better performance change this to 1. In snapShot version 4.04t and above this is forced to 1 automatically. Older version may need to be manually adjusted by doing the following:
- In Device Manager, right-click on COM port and select properties
- In the USB Properties window, click the tab ‘Port Settings’
- Click the button that says ‘Advanced’
- In the Advanced Settings window, change the latency timer to ‘1’
- Click OK, OK, then close Device Manager
