Using rb_visa gem to connect to HMC 8042 power supply unit

Highlighted

Hi, I'm trying to connect to a HMC 8042 power supply unit using the rb_visa ruby gem. When i try to disconnect and reconnect my ruby aplication to the psu, always on the third try i end up getting a coneection error (VI_ERROR_INV_OBJECT), which aparently means that there is an session already open to the device, however the only machine connected to it in my local network is my own.

 

Do you guys have any tips for that?
