Two Sound Devices: PCI and USB. Configuration problem.
 
I have two sound devices. One is an onboard NVidia PCI bus device. The second is an USB headset.
The problem is that when I boot up with the USB headset attached, only the USB sound device works and the NVidia PCI device is not recognized.
Code:

# cat /proc/asound/cards
 0 [Headset        ]: USB-Audio - Logitech USB Headset
                      Logitech Logitech USB Headset at usb-0000:00:02.0-2, full speed

If I then run 'alsaconf' the USB device disappears and the NVidia PCI device alone is shown:
Code:

# alsaconf

 0 [CK804          ]: NFORCE - NVidia CK804
                      NVidia CK804 with ALC850 at 0xf8105000, irq 225

If I then unplug the USB headset and insert it again, both devices will show and work properly:
Code:

# cat /proc/asound/cards
 0 [CK804          ]: NFORCE - NVidia CK804
                      NVidia CK804 with ALC850 at 0xf8105000, irq 225
 1 [Headset        ]: USB-Audio - Logitech USB Headset
                      Logitech Logitech USB Headset at usb-0000:00:02.0-2, full speed

How can I configure the system so that both devices will work from the get go, without the need to run alsaconf and remove/reinsert the USB device?

TIA
