I am using a Thorlab Smart Line Camera LC100 connected via usb to my computer, however, this is only one of many devices that could cause this error

Issue Details

I am getting an error "hex 0xbfff0072 the resource is valid, but VISA cannot currently access it" in LabVIEW when I have my USB device connected to my computer.

Solution

This error occurs when using third party devices, usually because another service is using your USB device as a resource as well.  

Here are some steps you can try to resolve this issue:
  • Try to close any drivers associated with this device
  • Reboot your PC
  • Stop running any services related to this USB device
