I've bought 2 different evaluation boards to know better LoRa with STM32 MCUs. First, I bought the Nucleo board with the Mbed shied from Semtech ( P-NUCLEO-LRWAN1). I've managed to connect it to my laptop and communicate through Serial port (flash, debug,...). I've install the STLink WinUSB and the UsbUser port drivers, available on this link : stsw-link009
After this, I bought another evaluation board with the Murata chip on it (B-L072Z-LRWAN1). I can connect it to my laptop, the default software is running (blinking leds,..) and I can see the device in my File Manager under the name : DIS_L072Z.
However, when I want to change the software or launch the debug mode in Kei UVision 5, I can't because there is no serial port for my device. In my Devices Manager I have new lines :
libusb (WinUSB) devices
-> STMicroelectronics STLink dongle (Libusb - WinUSB)
-> STMicroelectronics STLink Virtual COM Port (Libusb - WinUSB)
Does someone had also this problem ? How can I fix this driver issue?
