Issue Details

  • I am using a 845x device and I get error -301719
  • I am using NI I/O trace to monitor the functionality of my USB 845x. ON the SpiWriteRead¬†command, it is giving a status of -301719


Use the following steps to resolve this issue:

  2. Verify that the USB slot being used is a powered USB slot. On a desktop computer, this is usually on the back of the computer.
  3. Reinstall NI software on the computer including LabVIEW and the device specific drivers
