Hello,

Please find the Product details below:

NUCLEO-H743ZI2

I have purchased the above board for developing application to interface with the Lan9253 device.

I have installed the device drivers downloaded from the STMicroelectronics site.

Do I need any USB write/read access to work with this device as I’m getting USB device is blocked .

Please clarify as I’m not able to proceed with any development work on the board.

Thanks & Regards

For the best experience, use a Windows 10 machine, it should just work.

If you have Linux or Mac, USB setup can get complicated.

Note that the board has two USB connectors. The debugger one is on the side opposite to Ethernet and buttons.

The same debugger cable carries the virtual COM port connected to UART3 of the STM32.

Hi Pavel,
Kudos for your response.
By default all USB write access is blocked in our system. Do we need USB write access permission for using this controller board. If needed I need to find out the way for this.
Thanks & Regards
