USB CDC recognized by computer, but device manager says: ''This device cannot start. (Code 10)''

I have used CubeMX to generate the USB CDC driver. I connect my board to a computer and the device manager recognize it as: ''STMicroelectronics Virtual COM Port (COM15)'', but it has a error message: ''This device cannot start. (Code 10)''.

I have never worked with USB drivers before and do not know where to start to be able to solve this problem.Any ideas? #usb #cdc #vcp #usb #cdc

As I recall it was quite sensitive to the correct 32-bit or 64-bit driver being installed, so let's start there.

What version of Windows are you using? What version of the driver are you using? Is this with an ST EVAL board, or some custom board?

Win7 64-bit. I installed the 64-bit driver as explained in the readme.txt provided with the virtual com port driver.

It is a custom board.

Find the line in your startup file for stack size.  It is probably the folowing:

    Stack_Size      EQU     0x00000400 Change the value to 0x00004000 Find the line for the heap size in the same file.  It is probably the following:     Heap_Size    EQU    0x00000200 Change the value to 0x00002000

I came across the same problem recently, and this resolved it.

You are correct! The problem described was solved by increasing the stack and heap size as you said. Thank you!

I still can not send or receive data, but Windows now says the device is working properly. I tried setting the receive and transmit buffers and continuously send a message like shown below, but I do not receive anything. Since you did this recently, maybe you have some suggestion?

In your example, I don't see where you load anything into the buffer to transmit.  Not sure if its happening somewhere else that is not shown.

The base code I started out from had routines in usbd_cdc_if.c.  On the receive side, I'd wind up in CDC_Receive whenever a new character came in.  I then put some code in to extract the contents of the buffer.  There is also a CDC_Transmit function that sends data. Not 100% sure this is how to hook everything together, but its working, so I'm just going with it.  :)

Let me ask you something knapht.fnatt

Your device ''Virtual COM Port STMicroelectronics (COM15)''was in error, but when you connect the USB cable its corrected firmware(heap and stack size) this device started to work?Fixed the error?Thanks!!!

I am also getting this code 10 error on windows 7, what is the solution?

Change the value of the  ,

entry to the usbd_cdc.h library to 256
