Connected for the first time, Axoloti is not recognized

[mvl]

Hi everyone,
I'm sure this is a newbie question but I couldn't find an answer in the forum.
I bought an Axoloti on 2016 and only know I had the time to switch it on (I know, it's a shame!).
I installed on my MacOS 10.13.6 bith the Axoloti sw and runtime, connected themachine to the computer via USB, opened the Axoloti sw... and... nothing happens.

Precisely this is the log of the sw:

Axoloti version : 1.0.12-2-0-g7975cc87 build time : 09/04/2018 13:15:31 GMT
Link to firmware CRC E95BAC96

What should I do? Thank you for all the help.

Hey

Check this thread for some ideas:

No available USB device found with matching PID/VID

The symptoms you're reporting could be caused by a power-only USB cable, but you have already verified, great! The next thing to exclude is anything related to firmware. Could you try a "rescue flash": remove power from Axoloti Core, and then connect the micro-USB port to your computer while holding button S1. The LEDs will stay off when in DFU mode. Then select in the Board menu -> Firmware -> Flash (Rescue)... If the LEDs stay off, but you still get "No devices in DFU mode detected.", then …

Wait! I didn't! You mean that the USB cable is not enough for powering the Axoloti Core?
In that case what current would be ok? 600mA 9V I suppose, right?
I'll look for a proper transformer and check your suggestions!
Thank you!

The USB cable IS enough to power the Axoloti. But maybe you only have a USB cable without the data pins connected? The SUB cable sometime comes only for charging and without the data transfer pins connected.

The second post, from Johannes, which I linked above, suggested trying a flash rescue.

That was one of the things you could try

Well, I'm almost embarrassed, but... I can't see any button and any led on my Axoloti Core.
Where are they? Are we sure we are talking about the same model?

next to the usb Host connector, to the left, in the top edge of the board there are milimetric buttons and leds
