The stm32L476 cannot read the driver on some computers

[ppq]

Some parts of the computer can not read the STM32 bootloader in the device manager after connecting to the computer via USB, and the Unknown device will be displayed, but if you change some computers, you can read it correctly, and ask what this driver is related to the computer

Hi @ppq 

Sorry for the late response. Would it be possible to attach USB traffic for example using Wireshark?
