Hi. I have bought my brand new Arduino MKRZero to emulate a keyboard. When I plug it in, I get the following on COM6, which is listed as "Arduino MKRZero".

"This device cannot start" (Code 10)

I also get a new COM port connection, COM3, listed as a generic USB Serial Device.

In my IDE (2.1.0) I am given the following:

COM 3 opens on the Serial Monitor, while COM 6 gives a port monitor error:

I have tried a few things based on the following:

It worked well for the last few days but today i received after I wanted to upload a error that it is not connected. So I searched for the correct driver at the hardware manager, which I found after a longer time because all tutorials on the internet not worked for my problem.

- Updating drivers
- Rolling back drivers
- Using a different USB connector
- Restarting laptop

The reason why I ask is because I am attempting to use the following code in an Arduino, which, per my understanding, should print the letter "F" every second with my keyboard.

```arduino
#include <Keyboard.h>

void setup() {
  // open the serial port:
  Serial.begin(9600);
  // initialize control over the keyboard:
  Keyboard.begin();
}

void loop() {
    Keyboard.write('F');
    delay(1000);
}

```

However, no response is received.

Please let me know if more information is required, or if this is a code issue. I am on Win 10.0.19045, and attempted both the latest version and an alleged, more stable version of the MKRZero driver (Arduino SAMD Boards [32-bits ARM Cortex-M0+] version 1.8.13 and 1.8.9).
