If you do not see a red LED light up on the Firefly but instead see a flashing red/green LED, please make sure you are using the original short USB cable while charging. Using a long cable will sometime not work properly.
When you plug in the mini-USB cable the LED on the device will turn red. If you do not see a solid red light, please try using the computer USB port instead of the AC charger or vice versa. If this does not solve the problem try another short USB cable.
