-/* Controlling the sensor via the STK1125 vendor specific control interface:
- * The camera uses an OmniVision sensor and the stk1125 provides an
- * SCCB(i2c)-USB bridge which let us program the sensor.
- * In my case the sensor id is 0x9652, it can be read from sensor's register
- * 0x0A and 0x0B as follows:
- * - read register #R:
- * output #R to index 0x0208
- * output 0x0070 to index 0x0200
- * input 1 byte from index 0x0201 (some kind of status register)
- * until its value is 0x01
- * input 1 byte from index 0x0209. This is the value of #R
- * - write value V to register #R
- * output #R to index 0x0204
- * output V to index 0x0205
- * output 0x0005 to index 0x0200
- * input 1 byte from index 0x0201 until its value becomes 0x04
