Hello everyone,

I'm trying to use the USB STM32F042, used as a base example STM32F072 USB-discovery, but the windows me answer the following error: This device can not start (code 10).

I wonder if anyone has any examples of VCP for this chip working, or why he does not connect ...

Any idea?

Thanks ...

Try editing the file (.inf)

replacing the names

usbser -> Serenum

And then add a new legacy driver

with this file.

I don't understand what you mean by adding a new legacy driver with the *.inf file. I renamed all of

usbser

to

serenum

, then

I uninstalled the driver in Device Manager and re-pluged the usb connection -> then automatic driver instalation launched,

but finally message

''Device driver software was not succesfully installed'' showed up. So I still think it's the code matter.

The same issue solved here. Please, write there:

Try to increase heap size and stack size of (.s) file

Stack_Size EQU 0x00004000

Heap_Size EQU 0x00002000

I see this on the topic:
