I use two keyboards (laptop and USB connected), one works, the other doesn't. Why?

My code:

package main

import (
    "fmt"

    "github.com/MarinX/keylogger"
)

func main() {
        // k, err := keylogger.New("/dev/input/event14")
    k, err := keylogger.New("/dev/input/event3")
    if err != nil {
        fmt.Println(err)
        return
    }
    defer k.Close()

    events := k.Read()

    for e := range events {
        switch e.Type {
        case keylogger.EvKey:
            if e.KeyPress() {
                fmt.Println("[event] press key ", e.KeyString())
            }
        }
    }
}

I have two keyboards. One original from the laptop (/dev/input/event3) and one connected to laptop via USB (/dev/input/event14). When I use keylogger.New("/dev/input/event3") and press something on the laptop keyboard everything works as I expect. However, when I change to keylogger.New("/dev/input/event14"), that is, to my other keyboard and press something on that keyboard, nothing happens.

The result of sudo lsinput:

....

/dev/input/event3
   bustype : BUS_I8042
   vendor  : 0x1
   product : 0x1
   version : 43962
   name    : "AT Translated Set 2 keyboard"
   phys    : "isa0060/serio0/input0"
   bits ev : (null) (null) (null) (null) (null)

....

/dev/input/event14
   bustype : BUS_USB
   vendor  : 0x258a
   product : 0x3a
   version : 273
   name    : "SINO WEALTH Gaming KB  Keyboard"
   phys    : "usb-0000:04:00.3-2.3/input1"
   uniq    : ""
   bits ev : (null) (null) (null) (null)

....

Why is this happening? What should I do?
