Bad vertical mouse input using usb host shield on r4 minima

Hardware UNO R4 UNO R4 Minima

hello guys,
i m currently trying to get my mouse input using an arduino r4 minima official edition with a usb host shield bought on aliexpress, and move this input to my pc using the Mouse library

i found this code online :

#include <hidboot.h>
#include <usbhub.h>


#include <Mouse.h>

#include <SPI.h>

// Signed char can be between -128 to 127

int xDecal = 0;
int yDecal = 0;

int negMax = -127;
int posMax = 127;

// Mouse
int lmb = 0;
int rmb = 0;
int mmb = 0;


class MouseRptParser : public MouseReportParser {
protected:
  void OnMouseMove(MOUSEINFO *mi);
  void OnLeftButtonUp(MOUSEINFO *mi);
  void OnLeftButtonDown(MOUSEINFO *mi);
  void OnRightButtonUp(MOUSEINFO *mi);
  void OnRightButtonDown(MOUSEINFO *mi);
  void OnMiddleButtonUp(MOUSEINFO *mi);
  void OnMiddleButtonDown(MOUSEINFO *mi);
};

void MouseRptParser::OnMouseMove(MOUSEINFO *mi) {
  xDecal = mi->dX;
  yDecal = mi->dY;
};

void MouseRptParser::OnLeftButtonUp(MOUSEINFO *mi) {
  lmb = 0;
};
void MouseRptParser::OnLeftButtonDown(MOUSEINFO *mi) {
  lmb = 1;
};
void MouseRptParser::OnRightButtonUp(MOUSEINFO *mi) {
  rmb = 0;
};
void MouseRptParser::OnRightButtonDown(MOUSEINFO *mi) {
  rmb = 1;
};
void MouseRptParser::OnMiddleButtonUp(MOUSEINFO *mi) {
  mmb = 0;
};
void MouseRptParser::OnMiddleButtonDown(MOUSEINFO *mi) {
  mmb = 1;
};

USB Usb;
USBHub Hub(&Usb);
HIDBoot<USB_HID_PROTOCOL_MOUSE> HidMouse(&Usb);

MouseRptParser MousePrs;

void setup() {
  Mouse.begin();
  Serial.begin(1000000);
  
  if (Usb.Init() == -1)
    Serial.println("OSC did not start.");

  delay(200);

  HidMouse.SetReportParser(0, &MousePrs);
}

void loop() {


  xDecal = 0;
  yDecal = 0;
  Usb.Task();
  // Left Mouse
  if (lmb == 0) {
    Mouse.release(MOUSE_LEFT);
  } else if (lmb == 1) {
    Mouse.press(MOUSE_LEFT);
  }
  // Right Mouse
  if (rmb == 0) {
    Mouse.release(MOUSE_RIGHT);
  } else if (rmb == 1) {
    Mouse.press(MOUSE_RIGHT);
  }
  // Middle Mouse
  if (mmb == 0) {
    Mouse.release(MOUSE_MIDDLE);
  } else if (mmb == 1) {
    Mouse.press(MOUSE_MIDDLE);
  }

  Serial.print("x = ");
  Serial.print(xDecal);
  Serial.print(" y = ");
  Serial.println(yDecal);
  Mouse.move(xDecal, yDecal);
}

and it works for the most part, i only have one issue, but a big one : the x output is normal, but the y is only 0 or -1. I spend hours trying to figure it out, but no solutions yet :cry:

my mouse is an endgame XM1r, but the programm run fine on my brother's mouse, which is a razer deathadder V2.
at this point, i m completly lost, and i hope guy you ll be able to help me.

also i m not english so i could be not really clear sometimes don t hesitate to ask me to explain again

have a good day !

Check this out. I don't think you need the shield at all.

hey !
thank you for your response. i think i wasn t very clear on my intention : i want to get mouse input, then send it to the pc, but with a "correction" like for example aimimg better. the fact is that vanguard can t detect hardware cheat like that, but block all mouse event of script running on the pc, and don t allow 2 mouses to work at the same time when the game is running.

to get around with that, i need to get mouse input, add the "correction" on the arduino, then send only one modificated input to the pc, so vanguard doesn t block it.
