Issue Details

My cRIO keeps disconnecting from my PC when connected by USB. I can't ping it or see it in NI MAX. The only way to alleviate the issue is by unplugging the USB cable and by plugging it back in.

Solution

  • Try testing another USB cable.
  • Try using another USB port on your PC.
  • Update your drivers, BIOS, and OS. A bug could be causing your USB controller to disconnect from devices after a prolonged period of time.
