USB port monitoring

[wolbers]

Dear all,

I need Vizard to continuously monitor a port for incoming voltage changes (sent from an MRI scanner). I used to do this via the serial port, but it would be great if there was a way to switch to USB. Is anyone aware of a Python plug-in I could use, or would LabJack be helpful here?

Thanks for any hints,
Thomas

I did a quick search and found the following python project:

I have never used it so I don't know how good it is.
