Xenon: No serial monitor on win7 64 bit

Hello,

I’m not getting any USB-Serial output from my Xenon on a Win7-64bit machine. Is this some type of driver issue?

I can program the device over USB just fine.

Thanks.

Perhaps it’s like the argon, where factory new devices don’t expose the serial?

Like in this thread

Correct. The Argon, Boron, and Xenon all share this behavior in regards to serial not being setup/exposed until they are updated to rc.27 or later.

In Listening Mode the devices should still appear in DevMgr.
If not you need to install drivers.

Thanks for the replies.

I got this working, it was obviously a driver issue :slight_smile:

For reference:

Non working Win 7-64 bit serial monitor (but could still program the device in DFU mode)
Using Zadig:
In Listening Mode, “Xenon CDC Mode” using Driver “WinUSB (v6.1…)”
In DFU Mode, “Xenon DFU Mode” using Driver “WinUSB (v6.1…)”

======================================================

I changed the drivers to the following to get it working, but the handy “>particle usb dfu” command no longer works…?

Working Win 7 64-bit serial monitor
Using Zadig:
In Listening Mode, “Xenon CDC Mode” using Driver “USB Serial (CDC)”
In DFU Mode, “Xenon DFU Mode” using Driver “libusbK(v3.0.7.0)”

Happy now :slight_smile:

Thanks,
J.

Particle drivers for DFU and CDC are being worked on at the moment.
For the time being you should be able to use mode COMx 14400 to put your device into DFU Mode (as long you know which COM to use - particle serial list may help for that - or I usually assigne a fixed port for each platform)
