So when the pins are shorted, what it does is to randomly send logic highs and lows across the chip. I'm not sure which is the reset pin, but could be checked up on the datasheet. When the correct logic signal has been sent to the correct pin, the chip initiates as self-reboot due to an error.

When the chip reboots, the computer would be able to detect the player as there are changes in the hardware itself.
thx! thx! ....... thx! I really like it! You gave me the light to go on . Thanks! Thanks!
