Keyboard and Mouse not working from 1.8.0 release on

### Describe the problem

When using version 1.8.0 or higher of the platform, there are problems with HID functionality of the boards:

- Mouse emulation doesn't work at all on Windows machines
- Keyboard emulation doesn't work at all on Windows machines
- Keyboard emulation is incorrect on Linux machines

### To reproduce

#### Equipment

- Any of the boards supported by the platform.

#### Steps

##### Keyboard

1. Upload the following sketch to one of the platform's boards:
```cpp
#include
void setup() {
pinMode(2, INPUT_PULLUP);
pinMode(LED_BUILTIN, OUTPUT);
Keyboard.begin();
}

void loop() {
if (digitalRead(2) == LOW) {
Keyboard.print("hello");
digitalWrite(LED_BUILTIN, HIGH);
delay(500);
digitalWrite(LED_BUILTIN, LOW);
delay(500);
}
}
```
1. Open any text editor program, and give focus to the editor.
2. Connect pin 2 to ground.

🐛 If connected to a Windows machine, no text is typed.

🐛 If connected to a Linux machine, incorrect text is typed. For example:

```text
heloooooooooooohelohelohelooooooooooooheloooooooooooohelheloheloooooooooooohelooooooooooooheloooooooooooohhelooooooooooooheloooooooooooohelooooooooooooheloooooooooooohelheloooooooooooohelohhelohelhhhelhelohhe
```

##### Mouse

1. Upload the following sketch to one of the platform's boards:
```cpp
#include
void setup() {
pinMode(2, INPUT_PULLUP);
pinMode(LED_BUILTIN, OUTPUT);
Mouse.begin();
}

void loop() {
if (digitalRead(2) == LOW) {
Mouse.move(0, 200);
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
Mouse.move(0, -200);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}
}
```
1. Connect the board to a Windows machine.
1. Connect pin 2 to ground.

🐛 The mouse pointer does not move.

Has no effect on Windows, but seems to work correctly on Linux.

### Arduino SAMD Boards (32-bits ARM Cortex-M0+) version

- 1.8.0
- 1.8.1
- 284bc5a3185756cf6d107c002cc8841d772d07d4

### Additional context

When compiled with version 1.6.28 or 1.6.21 of the platform, both sketches work as expected on Windows and Linux.

---

Reproduced using library versions:

- Keyboard@1.0.2
- Mouse@1.0.1

---

Reproduced with the following boards:

- MKR 1000 WiFi
- MKR Fox 1200
- MKR GSM 1400
