@rickkas7, I’m in the same boat here. I have the Xenon on an Ethernet Featherwing attached to my PC and it is the gateway for my 3-device mesh network. On my corporate workstation, I have Windows 7 64-Bit. I ran the latest ParticleCLISetup.exe and it was unable to fix the warning triangle on the “Xenon CDC Mode” device. I am unable to see the Xenon via the CLI. A particle serial list returns no devices. Following your notes, the driver you point to in the git repo doesn’t list Mesh devices as an option… just Electron/Photon/P1.
I came across this post where @ScruffR recommending using zadig to install the libusbk driver. I installed zadig and chose the libusbk driver for the Xenon CDC Mode object… which makes the Xenon now show under “LibusbK Usb Devices” in device manger without a warning triangle. But a particle serial list does not show any devices. Also to note, after I did the zadig thing, I put the Xenon into listening mode (blinking dark blue) and there was no change to the device manager… but it was now under Libusbk devices if that matters.
I do not want DFU mode, I simply want to run the particle serial monitor to view debugging output. Is there a step I’m missing? You mention that Win 7 64-bit is not supported for DFU mode… but what about simple serial output monitoring?
