X-NUCLEO-CCA02M1 not recognized as sound device on PC

Hi,

I am testing X-NUCLEO-CCA02M1+NUCLEO-F401RE by following below instruction (page 7-9).

http://www.st.com/content/ccc/resource/sales_and_marketing/presentation/product_presentation/d3/44/de/b9/33/a0/4e/25/x-nucleo-cca02m1_quick_start_guide.pdf/files/x-nucleo-cca02m1_quick_start_guide.pdf/jcr:content/translations/en.x-nucleo-cca02m1_quick_start_guide.pdf

After that instruction, X-NUCLEO-CCA02M1+NUCLEO-F401RE should be recognized as

'STM32 AUDIO Streaming in FS Mode' in device manager of windows7 PC,

but not shown. Only virtual COM port is show in device manager.

I have tried below.

1. I followed another instruction on youtube, but I got the same result.

2. I build below firmware and debug it with system workbench

STM32CubeExpansion_MEMSMIC1_V2.0.1/Projects/Multi/Applications/Microphones_Streaming/SW4STM32/STM32F401RE-Nucleo/STM32F4xx-MEMSMIC1

But

connect/disconnect callback functions are never fired when I connect/disconnect USB mini cable on X-NUCLEO-CCA02M1.

(I have set the breakpoints at HAL_PCD_ConnectCallback and HAL_PCD_DisconnectCallback in usbd_conf_f4.c)

Does anybody success to use as sound device on PC with the combination of

X-NUCLEO-CCA02M1+NUCLEO-F401RE?

I also found similar question in this forum, but nobody answer...

I hope some hints or success information.

Thanks

I have switched to the combination

X-NUCLEO-CCA02M1+NUCLEO-F476RG and it works perfecty.

I just followed to the above same instruction with re-soldering resiter at SBx pads.

(

STM32CubeExpansion_MEMSMIC1_V2.0.1/Projects/Multi/Applications/Microphones_Streaming/SW4STM32/STM32F401RE-Nucleo/STM32F4xx-MEMSMIC1

)

If you success with

F401RE, please inform to this thread.

I don't want to throw away my F401RE...

Thanks

I have bought new NUCLEO-F401RE.

It works perfectly with X-NUCLEO-CCA02M1.

I compared the old NUCLEO-F401RE and new one, there is the difference of revision.

Old one is MB1136 C-01, the new one is MB1136 C-04.

I think some electric condition is difference.

But I could not found the documentation about revision of 401RE.

I give up!

Anyway, please check your revision if you encounter the same problem in future.

Thanks
