Expand "USB Audio 2.0" Kit to multichannel?

[sukandar]

Hi, is it possible to start with stereo using the "USB Audio 2.0" kit, then later expand it by connecting my own multichannel codec to the I2S lines?
Thanks.

Yes, no problem.

Thank you.
Nonetheless I had already decided to order the multichannel reference design, which I have just received and connected via USB. However, it doesn't show up in the list of USB devices (I'm on Mac). Just the rows of LEDs is blinking one by one. According to the manual it should show up as a USB Audio 2.0 device right out of the box. Am I doing something wrong?
Thanks!

You will need to download and flash the latest firmware i'm afraid. For some reason the factory is sending out boards with a simple LED flash program on them.
