Using GPIB-USB-HS with CentOS8

[hideharu3.14]

 Hello everyone,

I faced a problem and need some help.

I try to communicate with my instrument using GPIB-USB-HS and installed NI-VISA and NI-488.2 on CentOS8.

But it seems that my computer doesn't recognize GPIB-USB-HS.

Following messages is the output from PyVisa.

---

>>> import pyvisa as visa
>>> rm = visa.ResourceManager('/usr/lib/x86_64-linux-gnu/libvisa.so.20.0.0')
>>> rm.list_resources()
('ASRL1::INSTR', 'ASRL2::INSTR', 'ASRL3::INSTR', 'ASRL4::INSTR')

---

You can see there is not 'GPIB0::INSTR'.

Does this mean the computer doesn't recognize GPIB? where am I wrong? Do you have any idea?

Best Regard,

Hideharu

That device (GPIB-USB-HS) is not currently supported on Linux, see the 20.1 readme for 488.2.
