Saitake STK-4003

=HID Interface= This gamepad is a variation of the Sony DualShock 4 that matches most of its interface.

MAC / Serial Number
MAC is accessible by Feature Read on USB. MAC is present as hex string Serial Number on BT.

Temperature
The battery temperature value is always 0x00.

Pad Resolution and Stability
This pad's data resolution is close to that of a DS4, but slightly different. In normal use this is not noticeable. The pad will lock up and then output invalid data if it is overwhelmed. Sometimes this data is 0xfff and other times it is other out of range data. The simplest fix for this is to ignore touches outside the valid range, however even when doing that a false touch will get stuck emitted from the controller. The theory here is that the deltas are being summed between reports resulting in massively out of range values.

Enable Bits
On USB the bits  have no affect for this controller. It is impossible to set rumble and and not set the LED color or visa-versa. On Bluetooth the  flag has no affect. The  flag does double duty allowing both rumble and LED color setting. LED colors of 0x000000 are ignored.
