New to the linux life. Done this many times in Windows.
Using CentOS 7 in a VM on a MacBook Pro. Also installed are VMs for OSX and Windows 7.
I want to use PyVISA to control instruments via GPIB, so I need NI-VISA installed. I downloaded the iso image for NI-VISA-15.5.0 and got it installed, at least it finished without error.
When I plug in the GPIB-USB-HS to the USB port, I get a message from the VM manager, asking which VM I want to connect it to. If I select "Windows 7 64-bit", it enumerates and shows up as a device just fine, as it should.
If I choose "CentOS 64-bit", I get nothing. When I run ResourceManager under PyVISA, I see 4 ASRL instruments, but no GPIB. If I connect the GPIB-USB-HS to an instrument, the instrument does not appear.
If I look in /dev, I see no GPIB device. I *do* see nipalk.
I tried installing NI-488.2, but it refused to do anything becuase a newer or current version was already installed, I assume when I installed VISA. Is that the case?
I don't know what tests to do next to diagnose or give more info to the problem. Thanks for any advice.
