Centos 7 - pyvisa-py returns VI_ERROR_TMO while linux-gpib native python wrappers works fine

OS: Centos 7 (Linux DAQ 3.10.0-862.11.6.el7.x86_64 #1 SMP Tue Aug 14 21:49:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux)
pyvisa-py: 0.3.1
pyvisa: 1.9.1
GPIB: Bus 001 Device 002: ID 3923:709b National Instruments Corp. GPIB-USB-HS
Device: KEITHLEY INSTRUMENTS INC.,MODEL 2400
linux-gpib: 4.1.0-1.20180529svn1753.el7

The linux-gpib native python wrapper (Gpib.py) seems to work fine (after much tinkering) but I cannot get pyvisa + pyvisa-py to work. If there is additional info that I could report please let me know.

PS Is there a way to use the GPIB device without sudo?
