Axoloti core "not accesseable : busy?"


#1

Hi,
It's my second day with my axoloti core, and I can't connect it to the software anymore.
I've tried everything I could find in the community :
- uninstall drivers => unplug/replug hardware
- DFU mode => flash firmware (rescue)
- change usb cable
- change usb port

Axoloti's version : 1.0.10
PC : Windows 10

When I open the software I have this message :
USB device found
org.usb4java.LibUsbException: USB error 5: Unable to claim interface: Entity not found

When I click on "Connect" afterward I have this message
USB device found
not accesseable : busy?
USB device found
not accesseable : busy?
No available USB device found with matching PID/VID

Thank you for your help, I've had a great time with my axoloti so far :slight_smile:

Hi, could you try holding switch S2 while plugging in your board? Hold it until the red/green leds stop flashing alternately. That skips loading any patch (from internal flash or sdcard) at power up.

Another thing to watch out for, is not to open the Axoloti software two times, and trying to connect to the same board twice.

Thank you, it worked very well.

I'll try to follow your advice and not open the software twice. The first launch of the software is a bit long, it's tempting, though quite stupid, to click frantically on the axoloti icon.
