Hello every body,

I try to implement on my stm32f4-discovery a program with usb audio class to make windows use the board as speaker.

I worked on keil 4.54 and rl-usb under windows seven x64.

The problem is the following, when in the config file I activate audio class, windows does not recognize the board. I check the usb port with USBlyser. With other class : HID, Communication..., no problem, it works perfectly.

I try also to implement the program provided with the st library and i have the same problem. does anybody have a solution to make the board recognize by windows?

Thank you for your advice.
