Can I use this to record key's sequence entered from specific keyboard?

I am pretty new to AHK script. I very appreciate the wonderful work you did. I try to record the sequence of certain keys entered from a specific keyboard, and block them at the same time using the following code

#SingleInstance force
#Persistent
#include Lib\AutoHotInterception.ahk

global AHI := new AutoHotInterception()
keyboardId := AHI.GetKeyboardId(0x5131, 0x2007)
str := ""
keys := ["1", "2", "3", "4", "5", "6", "7", "8", "9", "0", "Enter", "?", ";"]
Loop 13 {
    name := keys[A_Index]   
    AHI.SubscribeKey(keyboardId, GetKeySC(name), true, Func("KeyEvent").Bind(name))
}
KeyEvent(name, state){
    global str
    if(state == 1){
       return
    }
   if(name != "Enter"){
    str .= name
   } else {
    xx := str
    str := ""
    MsgBox % xx     
   }
}

^Esc::
   ExitApp

Most time I got the right sequence, but sometime the "Enter" key won't be blocked. Sometime I got the wrong sequence, like I enter 123456, it shows me like 213456. That means the KeyEvent not firing in order.

I don't know what to do now, or maybe you have a better idea to implement the purpose mentioned at the beginning.

Thanks a lot
