[ecasound] USB-Soundcards under Linux

[Simon E. <sim...@vo...>]

Hi all,

I want to connect a USB-Soundcard under linux.
i have alsa installed.
Do i just need to connect the soundcard to the usb-port or do i have 
to activate something?
The soundcard is a cheap plastic stick with a c-media chipset in it.

Thanks for helping.

Greetings,
Simon
