One suggested remedy to this, which has some positive feedback, is to adjust the USB bus speed.
If it is blinking, as one user has reported it means the 5V power supply is dropping out. On model B (and presumably also the A ), the circuit has been improved to give a much more reliable warning of poor power quality. Note: A faintly glowing steady green LED means no boot code has ever been executed, as almost the first thing the boot code does is to turn the faint glow off!
The red power LED is wired to an APX803 supervisor. When flashing/blinking the green LED should be as bright as the red LED.
