I am having problem in using arecord with the imx6 and an usb audio card.

It gives me "arecord: xrun:1387: read/write error, state = PREPARED".

Using dmesg, I can see that there is a "cannot submit datapipe for urb 0, error -28: not enough bandwidth" when the usb audio card is plugged in.

I am able to play audio to it using aplay.

My usb audio card is Usb Audio Class 2.0 compliant.

Using cat /proc/asound/card2/stream0, I can see that it has 2 channels and 1 endpoint for both playback and capture.

My Linux version is 3.0.35 and the Ubuntu version is 12.04.2 LTS
