When I used the 1052 SDK version 2.15, mcuPresso IDE, and the usb_msc_cdc example, I found that the computer could only correctly recognize the USB drive but could not correctly recognize the virtual serial port.
It is also recommended that you try installing the driver mentioned in the "Installing the CDC driver for virtual_com and msd_cdc composite example" section of the readme. Or find it in the device manager and uninstall and reinstall it.
Hi,@Gavin_Jia, Thank you for your answer. After I installed its driver, it is now working properly. Can it install the driver automatically? If I switch to another computer, will I have to reinstall the driver. Thanks, zhangyuanhe
