I recently was told of a clever solution for this issue which I documented here: http://wiki.davincidsp.com/index.php/I2C_Tips#External_Slave_Device_Hanging_the_Bus_by_Holding_SDA_Low Basically the solution was to switch to "free data format" and perform a read. This will cause the I2C to start toggling SCL. I mention it here because I think the "free data format" mode is available on most processors. (The only device I know that does NOT support "free data format" is OMAP35x.) You might have a lot less processor-specific code with this approach and it would be applicable to more devices. I don't have any time to write the code/patch myself, but I thought I would at least toss the idea out there.
