Phidget 1055 open and close issue of LabVIEW

[Sherry]

I am using board 1055 with LabVIEW

I have 2 Phidgets connect to my computer,

•Is it possible for me to choose which Phidget to be opened ?
So far when I use “IR Open.VI" It will return to me any one of them to be opened.

• Can I close two phidgets together at the same time ?

I am trying to close 2 phidgets together , but it keep crashing my LabVIEW. Why this happened ? I am using LabVIEW 2013.
Is it possible for me to close them one by one ? or all of them at the same time ?

Thank you
