Opening a COM port on Windows fails about serialport-rs

[mlsvrts]

Hey!

• I tried using `r"\.\COM8" and it didn't work either.
• Yes, running from an admin command prompt also fails.
• I haven't tried PuTTy yet
• yes, it shows up exactly like the screenshots here zephyrproject-rtos/zephyr#17266 and with the same error messages

Unfortunately this is most likely an issue with your device drivers/USB descriptors, and isn't something that can be fixed by this library.

These issues can be tricky to debug, but I recommend taking a look at the device descriptor using USBTreeView as a place to start.

This shouldn't be required, but you could try the 'escaped' syntax: \\.\COM8

Other thoughts:

• Does it work if you try from an admin command prompt?
• I assume you can open the port in a program like PuTTy
• Can you share how the device appears in device-manager?
