Mustang GT 40: No device found #25
Comments
|
The device PID isn't supported and not listed here. The main question is though: Does it use the Mustang protocol, or something different like the LT series?
Nice, thank you! 😃 |
|
Ha! I didn't see the list... Shame on me. Regarding the similarity with the LT, I don't know, both products look surprisingly similar from an external point of view. I've only used the Fender Tone android App to access it via Bluetooth. I now wonder if the GT provides anything more than an audio interface over USB... I will check that. |

You can do a simple test:

That's a different error than expected. Do you get this error each time? |
|
No. If I start the application, I get the IO Error. |
|
This might be an indication of a different protocol. Usually it should fail with some kind of 'invalid id', not on USB writing. |
|
That is sad news. |

I'm trying to make plug work with my Mustang GT 40.
I took to ownership of the AUR package for this plugin as the previous versions did not compile anymore.
I'm using version 1.4.5.
Is there any successful attempt by someone fro this amp ?
Seems that the amp is seen by the system. I can use it as an audio device.
I don't see anything useful here.
Is there something I can try to make this work ?
