You will note that the Hardware ID’s are different. The first identities the Prolific USB to Serial (USB\VID_067B&PID_2303) while the second is a Prolific USB to PWM Port (USB\VID_067B&PID_2304). Where it says below to check your hardware.

You will be able to see what hardware you have in your system by the hardware ID. This is the pl2303 driver as you can see below. There is also the Prolific USB to serial driver Windows 10 download right down below. The pl-2303 usb-to-serial driver is below.

Install the Prolific USB to Serial driver on Windows

1. Double-click the PL-2303 Windows Driver Installer program;
2. The Prolific driver will ask you to install the PL-2303 USB-to-Serial driver will be installed on your computer;
3. The PL2303 Driver Installer program will now install the Prolific drivers;
4. Now close the installer program when it is installed.

Check the Prolific USB to Serial driver on Windows

Now check the driver check for the “Prolific USB-to-Serial Comm Port” device in Device Manager;

Check the “Prolific USB-to-Serial Comm Port” driver version by right-clicking on the Prolific Port and then click on “driver” on the top to check the driver version that you have on your computer. The Prolific USB to Serial Driver date will show below as is shown on the picture below.

Error 10 on the Prolific USB to Serial driver

If you get an error that the Prolific USB to Serial Adapter is not working. Then you will need to uninstall the driver on your computer and remove the Prolific USB to Serial adapter from your computer. Report and connect the Prolific adapter again and then wait until it looks for the Prolific USB to Serial driver.

Direct the software to where you extracted the driver to and install the Prolific driver from there. (Note also then you will need to check with chipset you are using). This as certain Windows dont work on certain chipsets. See the latest driver the Windows 8 is NOT supported in HXA/XA chip versions.

You will need to roll back your driver for the Prolific error 10 to stop. Download the older driver below which is the 2015 driver being version 1.12.0. As the drivers update older chipsets are excluded from the latest operating systems. Those are at their end of life. 

You can change the port settings on the Prolific USB to Serial Adapter settings as shown below. You will need to click on the port options on the top of the menu and then click on the advanced options which holds the advanced port options on the Prolific adapter as shown below.

Advanced Settings on the Prolific USB to Serial driver

Note what each of these advanced port settings does as shown below:

• USB Selective Suspend Idle Timer

This is the Idle Timer for the PL2303 chip to enter suspend mode and the default for this is 10 seconds. You can change this on the Prolific USB to serial adapter. Check your chip as this does not work on the PL2303SA chip. Also note that for the PL2303HXD/EA/RA, you need to write to OTPROM first.

• Disable DTR/RTS INIT signal

By default this is enabled. This will disable the DTR/RTS pin initialisation signal during driver load to disable the serial mouse or modem from being detected. Check this setting if your Prolific USB driver is not detecting your serial modem or serial mouse. The Prolific USB to Serial Adapter normally has this enabled as stated before, however for troubleshooting it is always best to check the advanced settings.

• Change DTR/RTS INIT Level Shift

The signal needs to be enabled as the default for this setting is TTL=HIGH as well as RS232=LOW.

• Disable Device USB Serial Number in Windows Registry

This is very important if you have many devices. The default for this settings is enabled. If you check this it will ignore PL2303 device Serial Numbers. If you disabled this then each PL2303 device even with different USB serial numbers will be treated as same device. This is more for troubleshooting your serial devices.

• Driver Buffer Size

This will set the buffer size of the serial device. The default settings for this is 4096.

Which Prolific PL2303 driver?

At the top of the page you can also see the driver hardware ID. These are

• usb\vid_067b&pid_2303&rev_0300
• usb\vid_067b&pid_2303&rev_0300 driver
• driver usb\vid_067b&pid_2303&rev_0300
• usb\vid_04e8&pid_6860&rev_0400&mi_00

These are all Prolific USB-to-Serial Comm Port hardware ID’s. You will note that the Prolific pl2303 driver ID above as they are the same hardware with different software versions. These tend to be people using the older operating systems. These hardware ID tags are from the 2015 versions of the hardware. These will be the PL2303HXA/XA/HXD/EA/RA/SA/TA/TB version chips.

The older driver below was the driver for the following Windows 32bit as well as 64bit versions: Windows 2000 SP4, Windows XP, Server 2003, Vista, Server 2008, Windows 7, Server 2008R2 , Windows 8, Server 2012, Windows 8.1, Server 2012R2 and Windows 10. The older driver might be what you are going to use more than the latest one right as the bottom of the page.

Technical support for Windows 98/ME/2000/XP driver stopped here. Windows 8/8.1/Server2012/Server2012R2 and Windows 10 are NOT supported with the PL2303HXA/XA chips. Mainly as these chips are no longer in production and had reached it end of life. Again check what chipset you are trying to get to work.

*You will need to roll back the driver for the pl2303 driver error 10 to disappear. Download the driver directly below. This is the 2015 driver which will work on older hardware. As stated each update leaves the older chipsets behind. In this version the chipsets PL2303H, PL-2303HX (Rev A), and PL-2303X as an example no longer work on Windows 8 and above.

Driver Update Changes

When Windows updates it might replace this driver with the latest driver. This will become a recurring issue unless you turn off the driver updates. To stop MS Windows from running the automatic driver updates. You will need to navigate to

Control Panel > System & Security > System > Advanced System Settings > Hardware > Device Installation Settings

Then choose “No (your device might not work as expected).”

The above will stop Windows from replacing the current driver automatically with the latest. This will stop the need for you having to reinstall the driver with the older driver that does work. This can be very annoying and frustrating.

PL2303GE	PL2303GS

What PL2303 chipset do you have?

You will note again that the Prolific USB to serial driver will need you to look at the chipset as well as the operating system. As you can see that Windows 8 does have its issues. So look at your pl2303 driver operating system version. The rtool in this driver cannot detect the HXA/XA chip in Windows 8 and above. This could very well be your problem when you cannot detect the hardware.

Checking your PL-2303 chip version

• Install the PL2303 Windows Driver Installer v1.8.0 or above
• Plug in your PL2303 USB device, now go to the Device Manager to check the COM Port number
• See in the directory and click on the PL2303CheckChipVersion tool and then set COM Port number.
• Now click on the Check button to show you the PL-2303 chip version.

This will allow you to see what exact hardware version of the pl2303 device you have. There may be different brand names. The internal hardware however will be Prolific. As explained above ASUS as well as HP and others have used this chipset in their hardware.

The December 2021 driver which is the latest driver does not support PL-2303X or XA, PL-2303HX (Rev A)  or PL-2303H. These chipsets have been dropped for any support for Windows 8 or above. See the 2015 driver above which will still work for the older hardware. These will now give you are error 10 on the pl2303 driver.

Common Issues

Likewise these are the most common issues with the Prolific. Additionally people don’t read the latest driver inserts. These will tell you which chipsets are no longer supported. You will then need to roll back to solve the issues. So hopefully you have found your driver. Lastly this solves the error 10 problem with the latest Prolific drivers and you have learned something new.

In addition the Prolific usb to serial is very prolific (literally) devices that you find in many other equipment. There are drivers on this website for other drivers with issues. Use the search bar on the side to find the others if you don’t have a pl2303 device but a different chipset series. There are a few on this website alone. Download the latest driver below. If it fails on your device. Come back and download the older version in the middle of this page, the 2015 one. Till I see you then 🙂 See also the Prolific USB to Serial Comm Port as well as the Prolific USB to Serial Comm Port Driver.
