WARNING jsdrv Unsupported port0 op: 4

[YouriWoelders1]

This warning only occours when i'm running it with WSL and everything seems to be running just fine. Should I be worried about this warning that keeps poping up like every second? I not sure why get it and what is means.

Basic code as example:

from joulescope import scan_require_one
import logging
logging.basicConfig(level=logging.DEBUG)

device = scan_require_one()
device.open()

Perform a basic operation
print(device.info())

device.close()

Log:

That error is the host code saying that it does not support the newer timestamp message coming from the JS220. I think that you have an old version of pyjoulescope_driver.

First, check your version:

python -m pyjoulescope_driver info

You should see pyjoulescope_driver 1.5.2. What does python -m pyjoulescope_driver info show for you?

To update:

python -m pip install -U pyjoulescope_driver joulescope pyjls

Running Joulescopes in a VM or WSL is not supported. While it may work, you may also find that the VM cannot keep up with the USB data rate from the Joulescope resulting in sample drops.

I was curious, so I took a look. Just getting WSL with Ubuntu working took a while. I already had WSL + Ubuntu installed.

I somewhat followed this guide. Here are my steps to get a JS220 working:

In Windows PowerShell as Admin:

winget install --interactive --exact dorssel.usbipd-win
usbipd list
usbipd bind --hardware-id 16d0:10ba
usbipd attach --wsl --hardware-id 16d0:10ba

In Ubuntu WSL:

sudo apt update
sudo apt upgrade
sudo vi /etc/wsl.conf

Edit the file to contain:

[boot]
command="service udev start"

wget https://raw.githubusercontent.com/jetperch/joulescope_driver/main/99-joulescope.rules
sudo mv 99-joulescope.rules /etc/udev/rules.d/

In Windows PowerShell as Admin:

wsl --terminate Ubuntu-22.04

In Ubuntu WSL:

lsusb
python3 -m venv ~/venv/joulescope
. ~/venv/joulescope/bin/activate
python -m pip install -U joulescope
python -m pyjoulescope_driver info

nano example.py

Copy / paste:

from joulescope import scan_require_one
import logging
logging.basicConfig(level=logging.DEBUG)

device = scan_require_one()
device.open()

# Perform a basic operation
print(device.info())

device.close()

I don't see the same warning as you do.

somewhat works. I get sample drops. I can open this JLS file in the Joulescope UI under Windows.
