opening programmer "snap_isp" on port "usb" failed

[lkoepsel]

I'm running Manjaro (Arch Linux) and am having problems using avrdude programming an Uno with a Microchip SNAP. I have been successful using the same hardware combination and command on macOS Monterey.

avrdude -c snap_isp -p atmega328p -P usb -vv -t 

On Manjaro, I get the following:

avrdude done.  Thank you.

On the mac, I get the following:

Any guidance as to how to solve?

Thank you,

avrdude: usbdev_open(): WARNING: failed to set configuration 1: Device or resource busy

Looks like missing udev rules to have the proper access right.
Ref: https://pypi.org/project/pyedbglib/2.10.0.43/

Or you have not installed hidapi.

Please install hidapi and set up the udev rules to see if that sorted out the issue.

[lkoepsel]

Thank you.
I have checked for both issues and neither seems to be the problem. I'll continue to debug and advise/close when I've solved it.

Do you have a VM system (Virtualbox, VMware) running?
In that case, check that the VM didn't grab the device. In those situations, I've seen similar error messages.

[lkoepsel]

Thank you, @dl8dtl, however, I'm not using a VM.

I did use the example from pyedbglib and was able to get information from the device:

pedgb.py
pyedbglib version 2.20.3.105
Debugger firmware is version 1.10.249
Target voltage is 5.10V

If I disconnect the target, the voltage goes to 0.3V as expected, so clearly pyedbglib is chatting with the board.

Bloom as in https://bloom.oscillate.io/ is also able to speak to the board. I thought I might have a contention/conflict, however when I uninstalled Bloom the problem remained.

I'll continue to debug...its a bit maddening.

Thanks to guidance from @navnavnav, I downloaded the latest artifact and it now works.
