The way the original driver for tm6000/tm6010 does varies from firmware version to firmware version. That part of the driver works fine for both tm6000 and tm6010, with the devices I used here, with firmwares 1.e and 2.7. However, on tm6000, it sends the firmware on packages with up to 12 or 13 bytes, and it requires a delay before sending the next packet, otherwise the tm6000 hangs. Another problem is that the firmware load may fail (due to the bad implementation of the i2c on tm6000/tm6010). So, the code should ideally check if the firmware were loaded, by reading the firmware version at the end. However, reading from i2c is very problematic, since it sometimes read from the wrong place. On the tests I did here, the original drivers weren't reading back the firmware version, probably due to this bug.
