* @caps: capabilities
* @usb_ctrl: which USB device-side controller is in use. Needed for firmware
* download.
* @firmware: name of the firmware file.
* @download_firmware: called to download the firmware when the usb_ctrl is
* DEVICE_SPECIFIC.
* @no_reconnect: device doesn't do a reconnect after downloading the firmware,
* so do the warm initialization right after it
*
* @size_of_priv: how many bytes shall be allocated for the private field
* of struct dvb_usb_device.
* @priv_init: optional callback to initialize the variable that private field
* of struct dvb_usb_device has pointer to just after it had been allocated and
* zeroed.
* @priv_destroy: just like priv_init, only called before deallocating
* the memory pointed by private field of struct dvb_usb_device.
*
* @num_adapters: the number of adapters in @adapters
* @adapter: the adapters
* @power_ctrl: called to enable/disable power of the device.
* @read_mac_address: called to read the MAC address of the device.
* @identify_state: called to determine the state (cold or warm), when it
* is not distinguishable by the USB IDs.
*
* @rc: remote controller properties
*
* @i2c_algo: i2c_algorithm if the device has I2CoverUSB.
*
* @generic_bulk_ctrl_endpoint: most of the DVB USB devices have a generic
* endpoint which received control messages with bulk transfers. When this
* is non-zero, one can use dvb_usb_generic_rw and dvb_usb_generic_write-
* helper functions.
*
* @generic_bulk_ctrl_endpoint_response: some DVB USB devices use a separate
* endpoint for responses to control messages sent with bulk transfers via
* the generic_bulk_ctrl_endpoint. When this is non-zero, this will be used
* instead of the generic_bulk_ctrl_endpoint when reading usb responses in
* the dvb_usb_generic_rw helper function.
*
* @num_device_descs: number of struct dvb_usb_device_description in @devices
* @devices: array of struct dvb_usb_device_description compatibles with these
* properties.

sequences found in logs:
[index value]

0x40 out byte
0x80 write addr
(0x00 out byte)*
0x80 read addr
(0x21 in byte)*
0x60 in byte
this sequence works:
0x80 read addr
(0x21 in byte)*
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.
