...

The Solution:

A few things to try:

  1. Use ctrl+c to kill the program and try running it again
  2. Unplug the Tau Camera from the computer for 10 seconds, reconnect, and try running the program again
  3. Try switching to a high-quality cable! If possible, try using a not-super-long USB-C to USB-C cable from a reputable brand. Then try running the program again.

Try to avoid:

  • Long cables
  • USB hubs
  • USB adapters

Try to use:

  • Shorter cables
  • Direct USB-C to USB-C if possible
  • Cables from reputable brands
