Hi.
The serialnumber of a composite device on Windows is not the same as that of a USB device.
This behavior is inconsistent with MacOS and Linux.
This behavior is also inconsistent with pyserial and qtserialport.
So we should change it.
The serialnumber we expect is the USB parent device. For example:
The pnpId is:
USB\VID_1209&PID_ABD1&MI_00\6&18DA7745&0&0000. The serialnumber contains the&character, which is incorrect. What we wanted was his fatherUSB\VID_1209&PID_ABD1\387132593131I refer to the code of qtserialport, https://github.com/qt/qtserialport/blob/dev/src/serialport/qserialportinfo_win.cpp#L470. Fixed this property.
I've also refactored other properties with cfgmgr32.h.
