midi device removed and rotary switch not work

[amokeamokes]

Hi!I'll say right away that I'm a beginner, this is my first such project :) I built minidexed on pi zero2wh\ PCM5102\ 1602 backpack\KY-040.

I wanted to test it using korg nanopad 1gen via OTG. And I ran into the problem that when minidexed is turned on, when a nanopad is connected to it via usb input, it turns off ( you can see in the last line that the device removed ) at the same time, the rotary switch is also turned off. But for the first split second of initialization, the rotary switch works! Everything works without a midi device, but I can't apply any midi to it to hear the sound... And yes, I took the power for the pi zero 2 from the PC, and tried the power adapter 5.0V=1.0A 5.0W. I had a thought that there was not enough power, but is it so? I don't understand :)

Hello, do you have another MIDI controller to test with?

Everything is working! I checked with another midi keyboard - the behringer umx490. And I tried to change the audio output to hdmi because there were suspicions of poor soldering. Thanks
