Ditto the PS3 BD remote driver, when moving to the kernel, lost its
ability to suspend after X minutes, which drains the AA batteries
inside it.

In the original system, the remote would get disconnected after less
than a couple of minutes, and reconnect as soon as you pressed a
button, and make sure that button got sent to the device.

Would be great if we could control this from user-space.
