GNSS Driver Install Class

    Question

  • For GPS driver with new GPS driver architecture (UMDF 2.0 based), GPS class is defined by Microsoft.

    Class - GPS

    GUID - {6bdd1fc3-810f-11d0-bec7-08002be2092f}

    However, when driver is installed with this class, Windows 10 (desktop) is reporting an error- "The install class is not present or invalid".

    As per our knowledge, For Microsoft built in class driver, there is no need to mention [ClassInstall32] in .inf file.

    If [ClassInstall32] is added in .inf,  it gets installed. But, driver build will not go through and give error - "Cannot specify [ClassINstall32] section for Microsoft defined class"

    I don't see GPS class({6bdd1fc3-810f-11d0-bec7-08002be2092f}) in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class when OS is installed.

    Need help to understand

    1. Is it necessary to add [ClassInstall32] in inf for GPS class driver?

    2. How to install GPS driver without having [ClassInstall32] in .inf file?

    3. Is there a need to have a GPS class registry key in following path to get GNSS driver installed?

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6bdd1fc3-810f-11d0-bec7-08002be2092f}

    4. Is Microsoft missed adding GPS class to the Desktop Windows 10?

    NOTE: I am not sure if it works for other Windows flavors like Windows 10 Mobile.
