Your answer to Archos 404 problem

Aha - that is a different matter. To get the computer to recognize the device: Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

You might want to double-check your Archos manual first - sometimes, instead of Volume +, they reccomend a different button.
