it works on my PC,the dmesg showed that the usbcore on your PC didn't register

the usb audio driver.

the right messages should look like:

[1519307.685164] usb 5-8: new high speed USB device using ehci_hcd and address

[1519307.821061] usb 5-8: configuration #1 chosen from 1 choice

[1519307.835790] usb 5-8: New USB device found, idVendor=1d6b, idProduct=0101

[1519307.835796] usb 5-8: New USB device strings: Mfr=1, Product=2,

SerialNumber=0

[1519307.835799] usb 5-8: Product: Linux USB Audio Gadget

[1519307.835802] usb 5-8: Manufacturer: Linux 2.6.31.5-ADI-2010R1-pre-svn7755

with musb_h

[1519308.163970] usbcore: registered new interface driver snd-usb-audio

while the last line can't be seen on your PC.

it should be OK now.

This problem is gone. Close it.

--- Vivi Li 2010-11-10 06:30:40

The problem is not gone completely.

Sometimes it still get errors on bf527-ezkit with error message:

g_audio gadget: Playback error: 1031

g_audio gadget: Playback error: -5

--- Vivi Li 2011-09-05 05:03:02

In latest trunk, bellow message shows:

g_audio gadget: Playback error: -32

--- Vivi Li 2011-11-23 05:41:06

Run test commands slowly will help reduce this kind of error. I updated gadget

audio test script.
