USB2 Serial Driver For Windows

How to Install a USB2 Serial Driver?

Add serial communication ports to your system with ease thanks to USB-to-Serial converters, making connecting standard RS-232 serial devices with PCs quick and effortless.

Verify that drivers have been installed correctly by accessing the Device Manager (by choosing Start > Settings > Control Panel > System Properties >Device Manager) and looking at your Device List – your COMx port(s) should appear here (COM1 through COM4).

Device Drivers

Before any USB device can be recognized and accepted by a computer system, its appropriate drivers must first be installed. These drivers typically come on the CD that came with it or can be downloaded directly from its manufacturer’s website; depending on which chip type was used in its serial converter device, different drivers may be necessary depending on which operating systems you intend to use it with.

Prolific Technology’s PL2303HX USB to Serial Bridge Controller requires drivers for Windows, MacOS (and Linux). Once these drivers have been installed application software can access it as though it were a conventional RS-232 serial port.

The USB serial core utilizes a set of functions that enable it to manage multiple virtual devices connected to one physical port. When it detects a new USB device, the core checks its associated tty_idx to see if there has been previously bound tty and closes or decrements it while decreasing the module count for the USB serial driver.

Once a tty is closed, the core invokes its serial_close() function to close down any active USB transfers and return it to a quiet state. Additionally, this process will write to the system log indicating which nodes this device was bound with.

USB Serial converters are an invaluable addition to modern PC and laptop computers that lack built-in RS-232 ports, making installation quick and effortless. Requiring only a USB port and power source, these devices make connecting devices easy; should they fail to function as expected however it can become frustrating; often this issue stems from missing or outdated drivers being the source. A driver update tool provides the easiest solution.

Often when plugging a USB device into a computer it will prompt you to search online for drivers or provide instructions on how to locate them; if this does not resolve the issue you can use a USB Driver Update Tool instead. These tools are especially beneficial when updating older devices, like the PL2303HX USB to serial bridge controller, that have not yet received updates from manufacturers. For more information about them and other Driver Update Tools please click here. Alternately, Microsoft Windows Hardware Dev Center and ntdev forums provide tips and techniques for USB client and device drivers, including how to perform hardware tests, capture traces, and generate log files. This information can help in understanding driver stack implementation as well as solving application communication problems that fail.

Isolated Adapters

USB to serial converters known as isolated adapters contain circuitry with optocouplers and TVS (transient voltage suppressors) to isolate data lines from each other, preventing high voltage spikes, ground loops, and noise from damaging computers or devices connected via the USB port. Most isolated adapters are utilized in environments with electrical interference issues or for devices of great value.

There are various kinds of USB-to-serial converters on the market. Most are single or four-port adapters; others may feature more ports. They may be powered either from within their USB port, or externally; using power from within reduces cable connections required while multi-port adapters require an external power source since their current cannot support driving them adequately.

Some adapters are plug-and-play; once inserted into a USB port they are recognized and installed automatically by Windows. Other adapters require setting jumper switches on the back to select either RS-232, RS-422, or RS-485 modes before plugging them into an available USB port for the installation of drivers. Once done so, follow any necessary procedures for the driver installation to have the serial device appear in Device Manager as “Ports (COM & LPT)” as well as in USB serial bus controller lists.

Linux provides multiple drivers for USB to serial devices. The built-in hid->com device works well for most single and dual port devices; other driver options include the simple serial, which works equally well, or USB serial which has all of the termios settings you would expect in a full-featured driver, including setting the baud rate, parity, flow control, and IO stop bits settings.

If you are using an industrial RS-232, RS-485, or RS422 USB to serial adapter, make sure that the device is set up with a male DB9 connection before connecting it to the USB adapter and plugging it into any standard USB port. Once properly configured and drivers installed, Windows should recognize and install appropriate COM port software which you can configure using a terminal emulator to mimic baud rates, parity, and flow control settings from your industrial device allowing for testing software and hardware without opening its enclosure.
