For most devices, the Ports device setup class and the Serial function driver provide the functionality required to operate serial ports and COM ports. To install serial ports and COM ports using these system-supplied components, do the following:

When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Common USB Device errors are ‘ usb port not working ‘, ‘device descriptor request failed error’ or ‘bugcodeusbdriver’ issues.

• The part 3-1.1.3.2 of the path says that on bus 3, it goes through port 1 (on southbridge), again port 1 (on motherboard), port 3 (still on motherboard), and then on port 2 of the external USB hub. Port 4 of this hub is used for an SD card reader.
• The one that communicates with our layout NCE power module through the serial port has stopped communicating and Windows Vista device manager reports the PCI serial port driver is missing and also the PCI simple communications controller and PCI bus controller drivers.
• I understand to open the port in.NET I can call the port by COM number. SerialPort s = new SerialPort('COM9'); s.Open; calls the device on COM9. However, if I run my program and serial port device on another computer port number could be changed, yet the device name is always the same on every computer.

• Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port.

• To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports.

For more information about installing serial ports and COM ports using the Ports device setup class and the Serial function driver, see the following topics:

If you do a custom installation of a COM port, you must comply with the COM port requirements that are defined in Configuration of COM Ports.

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.
