I just tried this exact code with my device and it also hangs on read.

I've now tried several versions of Linux on two hardware architectures (aarch64 and x86_64) and the behaviour is remarkably consistent across all the configurations.  I wonder if it has something to do with my device or with how I'm configuring pyvisa.

If you have a working setup, would you mind sharing the firmware version of your device and the output of pyvisa-info?  Thanks!

Did you use letter case like it is written in the manual?

In a bit of a breakthrough, I've been able to get this working on a Windows machine, with NI-VISA.

This tells me that the instrument is fine and the code is fine, and suggests the issue is with my Linux setup (which is where I need to get it working.)

I don't suppose any of you are successfully using this instrument on Linux?  Shout if you do -- I'd love to compare notes.

eTobey:
Can us do it without pyvisa? See my website for my way using sockets without pyvisa.

The device does not have a network interface, only USB.  Hence no sockets.
