The USB MIDI functionality on the USB A port has stopped working at OS 11.1 (KPP + PaintAudio Midi Captain Controller)

Dear Kemper technical support team,

My name is Wilson, and I am the designer of the PaintAudio Midi Captain series controller and a user of the Kemper Profiling Amplifier (KPP). I have recently updated my KPP to the latest OS 11.1, and I have noticed that external USB MIDI devices connected via the USB A port no longer function properly.

Not only am I experiencing this issue, but several of my friends who use the MIDI Captain + KPP combination for live performances are also encountering the same problem. They may face critical situations in their live performances due to the loss of MIDI control.

I have tried reverting the OS to the release version in Rig Manager 3.7, which restored the normal USB MIDI control, indicating that this issue is indeed directly related to the recent update to version 11.1. Also I see the USB-B port which the USB MIDI device function is active, I'm not sure if this new OS update had moved the USB MIDI from host to device protocol.

I hope you can assist us in resolving this problem.

Thank you for your attention and support.

Best regards,

Wilson
