USB mic not working after trying random settings

[K42F]

My (off-brand) USB mic was rooted through a VB virtual audio cable (windows 10).
After playing around with some commands in node command line, my mic stopped working and is not recognized anymore on any computer.

First, I ran the following in command line:

var portAudio = require('naudiodon');
var ai = new portAudio.AudioIO({
    inOptions: {
        channelCount: 2,
        sampleFormat: portAudio.SampleFormat16Bit,
        sampleRate: 44100,
        deviceId: -1,
        closeOnError: true
    }
});
ai.on('data', x => console.log(Math.max(...x)))
ai.start()
//ai.quit()

It worked fine and displayed various byte values.
My goal is to visualize audio volume in real-time. I thought I could try to lower some settings (to save on perfs) and see how it works:

var portAudio = require('naudiodon');
var ai = new portAudio.AudioIO({
    inOptions: {
        channelCount: 2,
        sampleFormat: portAudio.SampleFormat8Bit,
        sampleRate: 1000,
        deviceId: -1,
        closeOnError: true
    }
});
ai.on('data', x => console.log(Math.max(...x)))
ai.start()
//ai.quit()

After running those lines, the mic immediately stopped working. I tried to reconnect it with 3 different usb cables on 3 computers but none recognize it anymore.

I'll goo for an RMA but is there any reason why this happened?
Is there any risk trying random samplerates/sampleformat?

What happens when I start the portAudio.AudioIO ? does the mic's internal interface receives a 1000hz/8bit request?
