Connect RS232 device into any USB port on your laptop/computer. Allow 20+- seconds for Windows to attempt to install drivers automatically. If it's successful, skip to Step 2 below. However in 95% of cases, it will fail to automatically install the drivers. So you have to install drivers manually. Download the latest drivers, firmware, and software for your HP USB to Serial Port Adapter.This is HP’s official website that will help automatically detect and download the correct drivers free of cost for your HP Computing and Printing products for Windows and Mac operating system.

Description
USB 2.0 to serial Converter, DSUB 9M incl. USB A Cable 80cm, FTDI chipset
Provides a serial RS232 interface via USB 2.0
- Enables data exchange between PCs and serial peripheral devices (machine control systems, modems, sensors, etc.) via the USB port.
- Meets the USB 2.0 standard
- Incl. 80 cm USB extension cable
- FTDI chipset for individual configuration
The DIGITUS® USB 2.0 serial adapter is a practical solution for serial connectivity. RS232 serial interfaces are no longer available on new hardware, so the DIGITUS® USB 2.0 serial adapter enables data exchange between a computer USB 2.0 port and peripheral devices with serial interfaces (COM port, RS232). These include, for example, weather stations, sensors, machine control systems, set-top boxes, gaming consoles, PDAs, scanners, modems, ISDN adapters and many other peripheral devices. The USB 2.0 serial adapter is downwardly compatible with USB 1.1 and enables adaptable baud rates of between 75 and 128,000 bits per second. The customizable FTDI chipset is compatible with all common operating systems and also supports power management and remote wake up. A separate power supply is not required, because the device is powered through the USB connection.

Usb To Serial Adapter 9300-usbs Driver Updater

Device manufacturers of CDC Control devices

Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device.

In Windows 10, the driver has been rewritten by using the Kernel-Mode Driver Framework that improves the overall stability of the driver.

Improved PnP and power management by the driver (such as, handling surprise removal).
Added power management features such as USB Selective Suspend.

In addition, UWP applications can now use the APIs provided by the new Windows.Devices.SerialCommunication namespace that allow apps to talk to these devices.

Usbser.sys installation

Load the Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device.

Note

If you trying to install a USB device class driver included in Windows, you do not need to download the driver. They are installed automatically. If they are not installed automatically, contact the device manufacturer. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows.

Windows 10

In Windows 10, a new INF, Usbser.inf, has been added to %Systemroot%Inf that loads Usbser.sys as the function device object (FDO) in the device stack. If your device belongs to the Communications and CDC Control device class, Usbser.sys is loaded automatically.You do not need to write your own INF to reference the driver. The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows.

USBClass_02

USBClass_02&SubClass_02

If you want to load Usbser.sys automatically, set the class code to 02 and subclass code to 02 in the Device Descriptor. For more information, see USB communications device class. With this approach, you are not required to distribute INF files for your device because the system uses Usbser.inf.
If your device specifies class code 02 but a subclass code value other than 02, Usbser.sys does not load automatically. Pnp Manager tries to find a driver. If a suitable driver is not found, the device might not have a driver loaded. In this case, you might have to load your own driver or write an INF that references another in-box driver.
If your device specifies class and subclass codes to 02, and you want to load another driver instead of Usbser.sys, you have to write an INF that specifies the hardware ID of the device and the driver to install. For examples, look through the INF files included with sample drivers and find devices similar to your device. For information about INF sections, see Overview of INF Files.

Note

Usb to serial adapter 9300-usbs driver windows 7

Microsoft encourages you to use in-box drivers whenever possible. On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. Unlike desktop editions, it is not possible to load a driver through an external driver package. With the new in-box INF, Usbser.sys is automatically loaded if a USB-to-serial device is detected on the mobile device.

Windows 8.1 and earlier versions

In Windows 8.1 and earlier versions of the operating system, Usbser.sys is not automatically loaded when a USB-to-serial device is attached to a computer. To load the driver, you need to write an INF that references the modem INF (mdmcpq.inf) by using the Include directive. The directive is required for instantiating the service, copying inbox binaries, and registering a device interface GUID that applications require to find the device and talk to it. That INF specifies 'Usbser' as a lower filter driver in a device stack.

The INF also needs to specify the device setup class as Modem to use mdmcpq.inf. Under the [Version] section of the INF, specify the Modem and the device class GUID. for details, see System-Supplied Device Setup Classes.

For more information, see How to use or reference the Usbser.sys d
