-this sequence works:

-0x60 in byte
-
-Guess at API of the I2C function:
-I2C operation is done one byte at a time with USB control messages. The
-index the messages is sent to is made up of a set of flags that control
-the I2C bus state:
-0x80: Send START condition. After a START condition, one would normally
- always send the 7-bit slave I2C address as the 7 MSB, followed by
- the read/write bit as the LSB.
-0x40: Send STOP condition. This should be set on the last byte of an
- I2C transaction.
-0x20: Read a byte from the slave. As opposed to writing a byte to the
- slave. The slave will normally not produce any data unless you
- set the R/W bit to 1 when sending the slave's address after the
- START condition.
-0x01: Respond with ACK, as opposed to a NACK. For a multi-byte read,
- the master should send an ACK, that is pull SDA low during the 9th
- clock cycle, after every byte but the last. This flags only makes
- sense when bit 0x20 is set, indicating a read.
-
-What any other bits might mean, or how to get the slave's ACK/NACK
-response to a write, is unknown.
