Defining custom input device

Hello there, I am currently struggling so much with defining my custom input device. I think I've done everything properly but I can't get any data from my device. I'm sure the device works because I checked that in Device Monitoring Studio.

Raw hex data looks like that:

 01 11 f6 1d 92 4d ff 7f

Byte 0 -> Report Id
Byte 1 -> Buttons
Byte 2-3 -> PositionX
Byte 4-5 -> PositionY
Byte 6-7 -> Pressure

I defined state representation and device class in this way:

 [StructLayout(LayoutKind.Explicit, Size = 8)]
 public struct EpsonPenState : IInputStateTypeInfo
 {
     public FourCC format => new FourCC('H', 'I', 'D');
 
     [FieldOffset(0)] public byte reportId;
 
     [InputControl(name = "tipSwitch", layout = "Button", bit = 0, displayName = "Tip Switch")]
     [InputControl(name = "barrelSwitch", layout = "Button", bit = 1, displayName = "Barrel Switch")]
     [InputControl(name = "invert", layout = "Button", bit = 2, displayName = "Invert")]
     [InputControl(name = "eraser", layout = "Button", bit = 3, displayName = "Eraser")]
     [InputControl(name = "inRange", layout = "Button", bit = 4, displayName = "In Range")]
     [FieldOffset(1)]
     public byte buttons;
 
     [InputControl(name ="positionX", layout = "Analog", displayName = "Position X")]
     [FieldOffset(2)]
     public ushort positionX;
 
     [InputControl(name = "positionY", layout = "Analog", displayName = "Position X")]
     [FieldOffset(4)]
     public ushort positionY;
 
     [InputControl(layout = "Analog",name = "pressure", usage = "Pressure", defaultState = 0.0f)]
     [FieldOffset(6)]
     public ushort pressure;
 }

 #if UNITY_EDITOR
 [InitializeOnLoad] 
 #endif
 [InputControlLayout(stateType = typeof(EpsonPenState))]
 public class EpsonPen : InputDevice
 {
     public static EpsonPen current { get; private set; }
 
 #if UNITY_EDITOR
     static EpsonPen()
     {
         Initialize();
     }
 
 #endif
 
     [RuntimeInitializeOnLoadMethod]
     private static void Initialize()
     {
         InputSystem.RegisterLayout<EpsonPen>(
             matches: new InputDeviceMatcher()
                 .WithInterface("HID")
                 .WithManufacturer("EPSON")
                 .WithProduct("EPSON EPSON 725Wi")
                 .WithVersion("4660")
                 .WithCapability<int>("inputReportSize", 8)
                 .WithCapability("vendorId", 0x4B8)
                 .WithCapability("productId", 0x327));
     }
 
     public ButtonControl tipSwitch { get; private set; }
     public ButtonControl barrelSwitch { get; private set; }
     public ButtonControl invert { get; private set; }
     public ButtonControl eraser { get; private set; }
     public ButtonControl inRange { get; private set; }
     public AxisControl positionX { get; private set; }
     public AxisControl positionY { get; private set; }
     public AxisControl pressure { get; private set; }
 
 
     protected override void FinishSetup()
     {
         base.FinishSetup();
 
         tipSwitch = GetChildControl<ButtonControl>("tipSwitch");
         barrelSwitch = GetChildControl<ButtonControl>("barrelSwitch");
         invert = GetChildControl<ButtonControl>("invert");
         eraser = GetChildControl<ButtonControl>("eraser");
         inRange = GetChildControl<ButtonControl>("inRange");
         positionX = GetChildControl<AxisControl>("positionX");
         positionY = GetChildControl<AxisControl>("positionY");
         pressure = GetChildControl<AxisControl>("pressure");
     }
 
     public override void MakeCurrent()
     {
         base.MakeCurrent();
         current = this;
     }
 
     protected override void OnRemoved()
     {
         base.OnRemoved();
         if (current == this)
             current = null;
     }
 }

It seems to be chaotic now but I've tried 26 different configurations and none of them works. Device is present in Input Debug but none of the values is changing.
