Drivers Microsoft Port Devices App

When an application opens a port (using CreateFile), it appends an additional part to the device name string to specify which port on the device it is opening, e.g. On Windows 10, a device driver is an essential piece of code, which allows the system to interact with a specific hardware (such as graphics card, storage driver, network adapter, Bluetooth, etc.). Method 1: Microsoft USB Controller Driver Download via Device Manager Windows operating system has a built-in application named Device Manager to help users view and control all their PC peripherals. You can also use it to download and install the latest Microsoft USB driver updates on your Windows PC.


There is also a reverse driver available, which can map a location sensor (including GPSDirect) to a virtual COM port, for legacy software. To validate com port settings, you might need before installing the driver to connect to the GPS device directly (by using e.g. Turbo GPS or Hyperterminal) and verify that your settings work. Browse for driver software on your computer will come up. Select Let me pick from a list of device drivers on my computer. A window will come up asking to select the device type. Select Network adapters, as RNDIS emulates a network connection. In the Select Network Adapter window, select Microsoft Corporation from the Manufacturer list.

The Serial function driver always configures a legacy serial port as a COM port.

Serial detects the presence of legacy ports by reading corresponding COM port subkeys under the ..ServicesSerialParameters key. To install a legacy COM port, you must set a legacy COM port subkey for the device under this key. The COM port subkey contains the registry settings for a legacy COM port.

When Serial is loaded it determines which legacy ports were not previously detected by checking the LegacyDiscovered entry value for a legacy port. If this entry value does not exist or is zero, Serial performs the following tasks:

  1. Calls IoReportDetectedDevice to report the device to the Plug and Play manager.

  2. Sets the LegacyDiscovered entry value for the port to 0x00000001, which indicates that the port has been reported.

  3. Copies some of the entry values under the COM port subkey to the Plug and Play device key for the physical device object (PDO) that is returned by IoReportDetectedDevice.

  4. Serial sets the PortName entry value under the Plug and Play device key to the value of the DosDevices entry value under the legacy COM port subkey. For all other entry values that Serial copies, it retains the same entry value name. For more information about which entry values that Serial copies, see the Serial sample code provided in the Microsoft Windows Driver Kit (WDK).

The IoReportDetectedDevice call marks the port as a root-enumerated device. On subsequent system boots, the Plug and Play manager automatically configures the device based on the information in its INF file.

The Plug and Play manager creates the following compatible IDs for a legacy COM port: DETECTEDInternalSerial and DETECTEDSerial.
