Solid Red LED and No available USB device found with matching PID/VID

#1

I've checked all the old threads around the issue and could find no reference to the LED being solid red. I've tried 3 different cables (one which I know transfers data for sure), different ports, reinstalled multiple times, DFU mode (nothing happens), zadig, and tried on two different PCs both running Windows 10. Every single time I receive a solid red LED and no response from the computer. Please help! I am excited to use m Axoloti!

Not intending to hijack this thread; I'm simply having exactly the same problem down to DFU mode not doing anything- I can't even get mine to properly boot in DFU. On Mac OS 10.

sorry, not been around for a while.

hmm, trying DFU mode is the first thing to try...
can you confirm when you go into DFU mode the led remains off - if not, then I dont think its going into dfu mode (hence why computer still cant see it)

warning it can be a bit fiddly to do this, as you need to hold s1 whilst powering down, and its a tiny button.

also make sure you disconnect everything else from axoloti e.g. usb devices, gpio, and plug the axoloti directly into your computer.

also can you confirm have these axolotis ever worked? or is this a new problem?
(if it never worked, is it a new axoloti, or come from someone else?)

Here's where I am at now. I finally got it to connect outside of the case (Believotron) on my desktop pc. I thought this might be the reason it wasn't working, but when I tried again 2 weeks later, same problem.

#5

The red light comes right back on after following the DFU instructions.

This was one of our orders (Believotron), so we're sending a replacement and analyzing the return when it gets here.

Hello
I have the same problem with my Axoloti as blackironprison and half_health. Also the computer don't recognise when i go into DFU mode on Windows 10.
"No devices in DFU mode detected."
When i wait few hours it lights up but bug after a few seconds.
It is a new axoloti, purchased in January.
But it worked to intermittently during few days, except one day, when I upon detaching my controller (LaunchControlXL) from axoloti.

Today I have tried to start flashing firmware with DFU:
Link to firmware CRC E95BAC96
