I have a Razer headset plugged in. Everytime I restart the computer I have to unplug/plug the headset to make it work.

It even shows up the system:

lsusb
Bus 002 Device 002: ID 1532:001b Razer USA, Ltd 

It does not show up as a valid sound device in system -> preferences -> sound.

Does anyone know how I can make the headset "active" without replugging it to the computer?

You can try this:

Use:

/etc/modprobe.conf.local

add "alias modulename" depending on the driver name; use an editor as root.

If you have the same problem after resume try this:

The example talks about a wireless driver but essentially you're reloading a module automatically after sleep.

If your device isn't using a driver, try by restarting the sound driver.

but ChrisAD's original post says that it does work ... if you plug it in after turning on the PC. – CarlF Jun 15 '11 at 18:58
