Teensy 4.1 - Detect Windows /Control Key

Hey folks,

I indeed have searched quite a lot on the internet. Apparently nobody needs to detect if the Windows or Control or ALT key was pressed...
My goal is to build a Keyboard/Mouse passthrough. Everything is already working except for the fact that I cannot detect if the Windows / Control / ALT Key was pressed by the user.

Keyboard -> Teensy -> PC



Code: 
#include "USBHost_t36.h"
KeyboardController keyboard1(myusb);

void setup()
{
 myusb.begin();
keyboard1.attachPress(OnPress);

}

void loop()
{
  myusb.Task();
}

void OnPress(int key)
{
//Keyboard passthrough
    Keyboard.press(key);
    Keyboard.release(key);
}

Simple as that and it works for most of the Key but not for all..
The WIndows key for example wont trigger "OnPress"

In the end I would be happy to passthrough any key the user presses
 
Yes...
Try looking at the Raw keystrokes...
Code: 
// Simple test of USB Host Mouse/Keyboard

// This example is in the public domain

#include "USBHost_t36.h"

USBHost myusb;
USBHub hub1(myusb);
USBHub hub2(myusb);
KeyboardController keyboard1(myusb);
USBHIDParser hid1(myusb);
USBHIDParser hid2(myusb);

USBDriver *drivers[] = {&hub1, &hub2, &keyboard1, &hid1, &hid2};
#define CNT_DEVICES (sizeof(drivers)/sizeof(drivers[0]))
const char * driver_names[CNT_DEVICES] = {"Hub1", "Hub2", "KB1", "HID1" , "HID2"};
bool driver_active[CNT_DEVICES] = {false, false, false, false};


void setup()
{
  while (!Serial) ; // wait for Arduino Serial Monitor
  Serial.println("\n\nUSB Host Testing");
  Serial.println(sizeof(USBHub), DEC);
  myusb.begin();
  keyboard1.attachPress(OnPress);
  keyboard1.attachExtrasPress(OnHIDExtrasPress);
  keyboard1.attachExtrasRelease(OnHIDExtrasRelease);
  keyboard1.attachRawPress(OnRawPress);
  keyboard1.attachRawRelease(OnRawRelease);

}


void loop()
{
  myusb.Task();

  for (uint8_t i = 0; i < CNT_DEVICES; i++) {
    if (*drivers[i] != driver_active[i]) {
      if (driver_active[i]) {
        Serial.printf("*** Device %s - disconnected ***\n", driver_names[i]);
        driver_active[i] = false;
      } else {
        Serial.printf("*** Device %s %x:%x - connected ***\n", driver_names[i], drivers[i]->idVendor(), drivers[i]->idProduct());
        driver_active[i] = true;

        const uint8_t *psz = drivers[i]->manufacturer();
        if (psz && *psz) Serial.printf("  manufacturer: %s\n", psz);
        psz = drivers[i]->product();

        psz = drivers[i]->serialNumber();
        if (psz && *psz) Serial.printf("  Serial: %s\n", psz);

        // Note: with some keyboards there is an issue that they don't output in boot protocol mode
        // and may not work.  The above code can try to force the keyboard into boot mode, but there
        // are issues with doing this blindly with combo devices like wireless keyboard/mouse, which
        // may cause the mouse to not work.  Note: the above id is in the builtin list of
        // vendor IDs that are already forced

Also note with: shift, ctrl and Alt, they also set the MOD settings...
 
Maybe in some future KeyboardController we should consider adding APIs that mirror the USB device Keyboard class, like the non-US layouts, reading as Unicode chars or UTF8 string, and mapping to the same keycodes as device mode uses.

We (mostly) have this sort of API consistency for MIDI and Serial...

Sweet! Thanks.
In fact I already was catching RAW input, but I did it wrong as I can see with your example.
Appriciate the help!

Maybe in some future KeyboardController we should consider adding APIs that mirror the USB device Keyboard class, like the non-US layouts, reading as Unicode chars or UTF8 string, and mapping to the same keycodes as device mode uses.

We (mostly) have this sort of API consistency for MIDI and Serial...

Paul, not sure what you mean here.
Currently the code is setup to convert the raw scan code keyboard data using the keylayouts stuff in core, which I believe should use the keyboard layout option in the tools menu. Have not tried it in a long time, to see if it catches all cases.

The problem keys like the Windows key is that it does not MAP to a normal key in the tables... Also CTRL+SHIFT+ALT are used as modifiers, in the translation... I know there are things we don't probably handle, like ALT+1+3+4 building special key ...

Note we also try to catch in the "Extras" options some of the other Standard but not ASCII stuff, on many keyboards, like the "System Keys" and the like like Volume UP/Down,
