How to manually scan for usb audio device?

**Chiel92** · January 30th, 2013

Hi,

Sometimes my m-Audio Fasttrack Pro usb soundcard doens't get recognized. That is, it's not listed in the PulseAudio Volume Control, and no sound comes through. However, running

Code:

lsusb

gives me a list in which the soundcard is included.

How can I make the audio system aware of the usb soundcard?

PS: I currently 'solve' it by either rebooting, or keeping plugging and unplugging the usb connection till it's recognized. But this is annoying to do every time.

Have you tried restarting pulseaudio after plugging the usb soundcard in?

Code:

pulseaudio -k

To see what's currently connected on your USB ports use:

Code:

lsusb | more

But I don't think that this is what you're looking for regarding the issue you appear to be dealing with.

Regarding specifically your issue, I think that this thread Create your own udev rules to control removable devices, will probably be of great assistance.
