visa session won't close

Ever since updgrading to Mac OsX 10.11 in labview 2014 visa sessions will not close. The close session VI runs without an error but the USB port remains claimed by Labview until I physically unplug the device from the computer. This never happend with 10.10

It is strange that it worked fine in the previous version... Does it also free up if you entirely close out of LabVIEW?

I just checked and no, it looks like quitting out of labview completely will still keep the port locked down.

Interesting, I've never seen that before. And are you sure it's not selected in MAX or some other program? (I only ask because I've done that before...)

 

Besides that, maybe you could upload your code and see if anyone notices anything odd.

to be sure if your labview close the visa or not it is not relate to labview  go to tool and then option mark the icon that claim labview close visa port every time that  vi stop if you visa port did not stop yet so problem is relate to your hardware or driver

False alarm. In looking into this it appears that it is actually a firmware bug with my hardware. For whatever reason this bug is not present on windows or earlier versions of mac.
