Windows 10 PC not recognising STM32 F411E DISCO board as an external device and as a COM port

HS.19

Hey guys,

I have connected two ST eval boards with my PC running Windows 10. When I connected NUCLEO_L432KC it was recognised as a COM port in the device manager and in "This PC" it showed up as a device and contained a txt file and a HTM file with the name MBED. When I connected 32F411EDISCOVERY board with my PC it did not show as a COM port in the device manager and also "This PC" did not show any device as connected till now(not even as a unrecognised device). The device manager irrespective of any boards connected to it, has one icon as unrecognised device which ruled out the possibility that the DISCO board is shown as an unrecognised device.

Some of the things that I tried till now to solve the problem and nothing worked are below:

1. I tried to refresh and connect once again.

2. Checked connecting the board in other PCs. Same response.

3. Installed STSW-LINK 007, STSW-LINK 009, STSW-STM32102 drivers and refreshed and connected the board once again.

I heard that the flash memory of the DISCO board was completely erased and reprogrammed once, but don't know the details of what exactly was programmed back.

Please help me to solve the issue. Thanks in advance!
