摘要
Disclosed are a USB device and a method thereof for automatically recognizing a Microsoft windowing operating system version. The method comprises: a USB device accessing a host; the USB device reporting an MOSD supporting a configuration parameter designation function to the host, a designation configuration value of the configuration parameter designation function being set to the Nth configuration parameter; when the USB device detects that the host obtains a configuration descriptor corresponding to the Nth configuration parameter, determining that a Windows operating system version is Win8; when the USB device detects that the host obtains a configuration descriptor corresponding to the first configuration parameter, and if the USB device receives only one query instruction delivered by the host, determining that a Windows operating system version is XP; or otherwise determining that the current Windows operating system version is Vista or Win 7. Embodiments of the present invention can distinguish Windows operating system versions without installing any program on a host.
