Hi @greenaddress . The USB drivers (MSC, HID and UVC) use wprintf to handle USB string descriptors, which are UTF-16 encoded. We will fix in upcoming releases

@greenaddress The error was actually in the MS example itself. It was fixed internally. This issue will be automatically closed when the commit is synced to esp-idf github
