usb headphones question

[Josh Kennedy]

Hi
In order to use my usb headphones I have to first plug them in, reboot the computer and then they show up in my list of sound choices. I am using ubuntu lucid vinux 3.0. But if I plug them in without rebooting if I use alsamixer alsamixer says they are there but if I go into the ubuntu alt f1 menu into system preferences sounds I cannot choose them. I can only choose them as a sound card option after rebooting. Why is this? Can this be changed? Ubuntu picks up other devices without rebooting so why must I reboot just to use usb headphones? email off list at jkenn337 at gmail.com
