Photon 2 Wifi Setup Serial Timeout on Setup (solved myself)

Connectivity

! Something went wrong: Serial timed out while initially listening to device, please ensure device is in listening mode with particle usb start-listening

EDIT: works fine in Windows 11 with Chrome. My issue was Linux with CLI with Linux with Chrome.

I'm pretty sure the item is failed, as received. First time in about 20. I'm trying to use it anyway. I can get it to 'mostly work' by manually forcing DFU and installing my application. But even if I do setup-done and get normal lights the 1) blue setup light pops back on. The are two other functional problems: 2) no wifi at all. 3) occasional serial glitches. These aren't show-stoppers and the unit can be a prototype tester.

I bought the unit last December and just got around to using it

I've tried everything I can think of such as factory reset etc.

The only other useful clue is that the web installer identifies the device as 'P2 paired'. So I've tried turning off every bluetooth device I can find. None of my other devices had the problem and I'm not sure if they also displayed as 'paired.'

You probably did not get Wi-Fi credential set. You could try repeating setup again or use the configure wi-fi tool or particle serial wifi to set them. That should eliminate the blinking dark blue. setup-done isn't used on the Photon 2.

The recommended version is 5.6.0 because if you use a later version like 5.8.0, there are currently intermittent USB serial issues. These will be fixed in 5.8.2.

I did all that. What I hadn't done is try using a Windows machine instead. The setup process worked fine. I may still have serial glitches (serial.read ignored) and I'll watch for that

oops didn't read carefully. I was using 5.8.0. Explains all.
