Hello
I am having difficulty getting the computer to communicate with an STM32.
The requirement is to get the STM32 device to communicate directly with a PC over the USB, using the CDC module.
When I connect up the device to the laptop and look in Device Manager, the STM32 device is shown with its name under ‘Other devices’. The Properties gives a message saying “No drivers are installed for this device�? and shows it’s location as “Port_#0003.Hub_#0001�?.
I understand that the STM32 device should communicate with the computer via the ‘Usbser.sys’ USB serial driver under Windows 10 (https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/usb-driver-installation-based-on-compatible-ids). This has been backed up by a Damogram Labs example (https://damogranlabs.com/2018/02/stm32-usb-cdc/).
I’ve updated the driver using http://batcmd.com/windows/10/services/usbser/ but this did not solve the issue.
I have got this far by following ST’s “STM32 USB training – 09.3 USB CDC libusb device lab�? video and have used a NUCLEO-F413ZH instead of the training’s NUCLEO-F446ZE. This suggested installing the libusb0 driver but I’m sure that this is not the issue due to the above two pages (further @TDK in a previous question regarding ‘signatures’ believed that there should be a native driver and @Pavel in the same question was quite encouraging I that I stay away from such things �?� ).
I have also tried this device on a different laptop with the same results as above.
Has anyone had any similar experiences or may know or have an idea what I’m doing incorrectly?
(This is a 'follow-on' from another question regarding using signatures on drivers)
Thanks
Ron
