What is PL2303 USB to Serial driver?

Connecting RS-232 serial devices to a Windows host computer with USB connectivity is made easy with the help of the PL-2303 USB to Serial converter.

How do I fix issues with Prolific PL2303 drivers?

Issues with the driver generally arise due to three reasons, either the driver is outdated, corrupt, or there is a bug in the current version. While there could be other reasons, they don’t have to do specifically with the driver.

Amongst the three issues listed earlier, you can manually update the driver using the steps listed in the previous section. For the other two, i.e., a corrupt driver or a bug in the current version, the methods listed below should work.

1. Reinstall the driver

1. Press Windows + S to launch the Search menu, enter Device Manager in the text field at the top, and click on the relevant search result that appears.
2. Locate and double-click on the Ports entry to expand and view the devices under it.
3. Now, right-click on the Prolific USB-to-Serial option and select Uninstall device from the context menu.
4. Click Uninstall in the box that appears.

Once done, restart the computer, and Windows will automatically install a fresh driver for the device. In case that doesn’t happen, you already know how to install Prolific PL2303 driver Windows 11 manually.

Reinstalling the driver is a simple fix employed when the installed one is corrupt. But the focus here is on identifying the corrupt driver, which too is simple. Look for the driver with a warning mark near the bottom-left corner of its icon.

2. Roll back the driver update

1. Press Windows + X or right-click on the Start icon to launch the Quick Access menu, and select Device Manager from the list of options.
2. Now, double-click on the Ports entry.
3. Next, locate and right-click on Prolific USB-to-Serial and select Properties from the context menu.
4. Navigate to the Driver tab.
5. Click on the Roll Back Driver buttton.
6. Now, choose a reason for rolling back the update, and then click on Yes at the bottom to start the process.

When you update a driver, Windows will keep the files for the previously installed version in case things go wrong and you have to revert to the previous version.

And this is what we do when we talk about rolling back a driver update, basically going back to using the previous version.

But if you see the Roll Back Driver option greyed out, it means that either the driver has not been updated or Windows didn’t store the files for it.

Why doesn’t Windows automatically install the drivers?

Whenever you connect a new device or peripheral to your computer, Windows should ideally automatically detect it and download the relevant driver. But that’s not the case for every piece of hardware.

The driver will only be installed if it has been submitted to Microsoft and is approved by them. Device manufacturers are supposed to submit their drivers and get them approved by Microsoft to get them released along with other Windows updates.

But several of them don’t do it. Some are due to a lack of resources, while others may find uploading these drivers on their official website a more convenient option.

There are manufacturers who, though, get the driver approved initially by Microsoft but upload the subsequent updates on their website.

Apart from that, several users unknowingly configure the settings such that Windows doesn’t automatically search for updates.

Besides, there are times when the driver is already installed on the computer, but you may still be unable to access or use the relevant device.

What if the Prolific PL2303 USB-to-Serial driver is not working on Windows 11?

Several readers complained that the Prolific PL2303 USB-to-Serial driver doesn’t work on Windows 11.

If this is also your case, try following the following solution:

1. First, download and install the Prolific driver, as shown in the first solution from this guide.
2. Click the Search icon on the taskbar, type device manager, and open the app from the results.
3. Expand the Ports (COM & LPT) section by clicking on it.
4. Right-click on the Prolific driver and select Update driver.
5. Click Browse my computer for drivers.
6. Now click Let me pick from the list of available drivers.
7. Select the latest version and click Next. If that doesn’t work, you can try the procedure again and select a different one.
8. Carry on with the installation, then restart your PC.

So, if you wondering why does Windows 11 not recognize my USB device, it’s likely that the relevant driver has not been installed, and, as a result, the OS can’t identify or connect to the device.

That’s all there’s to know about installing the Prolific PL2303 driver in Windows 11, along with the two most effective troubleshooting techniques. Also, you can similarly download the Prolific USB to the serial driver in Windows 10.

Unfortunately, that didn’t work for me. If memory serves, the error code I got was something along the lines of «THIS IS NOT A PROLIFIC DEVICE. PLEASE CONTACT YOUR SUPPLIER.» When I delete and let WIndows Update try it, I get an error about the driver not being supported on Windows 11.

I went on the Adafruit website prepared to buy a new cable that’s compatible with Windows 11, and found out they have a link to the older driver! Link to the Adafruit page: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/software-installati…

After downloading the zip, I installed the driver, and rolled back the software as described somewhere in this thread.

It’s really frustrating that Prolific has a pretty terrible website, and that they purged a bunch of links that have worked in the past. Also, without knowing too much about the difference between win 10/11, it seems like the drivers should work fine from 10 to 11? Like, there’s no reason why a driver from 2005 should work, and a driver from 2020 does not. 

Anyway, hope this helps someone out there!

Answer

1. First, make sure that the driver is up to date.
2. Go to Device Manager and right-click on the “Pl2303” device and select “Update Driver.”
3. If the driver is already up to date, try reinstalling the driver.
4. If that doesn’t work, you may need to uninstall and then reinstall the driver.
