+ TeleMini v3 can be updated directly over USB, but has no USB connector
+ on the board. Instead, the USB signals are present on a row of 6
+ holes adjacent to the copyright assertion in the silk screen. Thus,
+ updating firmware on TeleMini v3 requires making up a special cable,
+ after which you can treat it just like TeleMetrum or TeleMega. Many
+ USB cables seem to follow the color code of red is +5V, black is GND,
+ green is USB +, and white is USB -. On TeleMini v3, pin 3 which has
+ a square copper pad is ground, pin 1 is USB -, and pin 2 is USB +.

You may wish to begin by ensuring you have current firmware
images. These are distributed as part of the AltOS software
bundle that also includes the AltosUI ground station program.
