 * Only firmware version 1.43 (latest OSX El Capitan) works with the driver.
 * The driver will complain about 1871_01XX.dat (or similarly named) files missing. This error can be ignored. The .dat files contains sensor calibration settings that will improve image quality. The error looks something like this:

 ### How can I help?
