Here are my problems:
1.I tried the instructions for the BF527 EZKIT to enable the kernel audio card and USB gadget audio. I got "soc-audio: probe of soc-audio failed with error -22" error.
2.If I try build the kernel as BF527, I don't have the error and I can see the ssm2602 under the ALSA list. But the USB gadget still does not work. Please help!
