Firmware Version Identification (Blink Pattern after Power Up)

To identify the current firmware version in the device, a specific blink pattern is displayed after power has been applied via one of the USB ports:

The first LED blinking YELLOW for N times, like, say, two times:
Major Revision Number is N = 2

Then, second LED blinking CYAN for K times, say, three times:
Minor Revision Number is K = 3

Effective firmware Version is N.K, with K displayed with two digits. For the example:
Version = 2.03

There might be additional blink patterns following after the firmware version, like both LEDs blinking RED three times which indicates the used firmware is a special beta/test version.
