[ISSUE] No Device Found on Particle Workbench

I am currently attempting to flash to my argon on particle workbench, but it says that no devices are found. My device is plugged into my computer via USB and is on DFU mode. Here’s the whole error message:

:::: PUTTING DEVICE INTO DFU MODE

Does anyone know why this might occur/how I can fix it? Thanks!

this is the info we need to help troubleshoot:

Have you checked with a different USB cable and port?
Does the device show up in Device Manager?

I have tried multiple different USB cables and ports, but with all of them it does not show up in Device Manager.

And have you tried a different cable?
Do you hear the “attached new device” Windows sound at all when you plug it in?
Also if all your USB ports happen to be 3.0 or C try using a USB 2.0 USB hub in between.

Yep, I have tried a few different cables, but I don’t hear the sound when I plug it in.
I believe all of my ports are USB 2.0. They would be blue if it was USB 3.0, right?

Thank you for your help thus far!

Can you try on a different machine?
If that also doesn’t change anything you may need to file a suppor ticket at support.particle.io

I have tried that already, and unfortunately, it didn’t work.
I just filed a support ticket–thank you so much for redirecting me to that!
