What steps will reproduce the bug?
Listing devices from Serialport.list() on windows.
What happens?
Since serialPort@10.5 the return serial number in the port infos is no longer correct.
Result of SerialPort.list()
pnpId: USB\\VID_6244&PID_0622&MI_00\\6&FED21C1&0&0000
serialNumber: 6&FED21C1&0&0000 // wrong SN
What should have happened?
Expected result of SerialPort.list()
pnpId: USB\\VID_6244&PID_0622&MI_00\\6&FED21C1&0&0000
serialNumber: 000002003006
Additional information
Issur not detected on macOs
I've also noticed that windows created a new folder in the registry with &MI_00 at the end.
I can confirm that starting with v10.5.0 the Serial Numbers on Windows are not reported correctly.
I also have a device with multiple CDCs that opens up multiple Serial Ports.
Instead of the correct Serial Number the last part of the pnpId is used.
What is also broken in v10.4.0 is that if I connect two USB devices with the same reported Serial Number, Windows replaces it with a fake one. I did not found a way to query the registry / wmi for the correct serial number in this case. Might just be a Windows issue.
