After I've installed the VCP driver and connected USB to the board I get an error in device manager:

''This device cannot start(code 10)''

but when using Windows XP no error occures ..

Any idea on how to fix it is welcomed

Found the problem, the VIRTUAL_COM_PORT_DATA_SIZE should be 64

and I've used 255 that works on XP but not on Win7

Hi,

I'm having a code 10 problem, but I am using the STM32F411 and I've used the cube to configure the virtual com port.  I cannot find the VIRTUAL_COM_PORT_SIZE macro anywhere.  How do I fix this?

Thanks!

This thread is from *2011*, neither the F411 nor Cube existed in that universe.
