Pl2303 Windows 11

[Juliano Nichols]

azzido no problem, windows 11 always updates drivers if newer cones out if the software don't see the programer it's easy just removed the recent update driver by windows 11 and all will work perfect. The drivers I provide are from the pl2303 maker so the latest for Windows 11 and 10. Regards

For reference, I attache the 2 drivers that work for me to this message. Only one is needed, just that they have different install methods (one is .exe and the other is right click on the INF), if you run the .exe version and you already have another version of the driver it will ask you if you want to uninstall (which I usually do) and then run again the .exe to install the driver.

I have a few handheld radios that I need to update the frequencies and when I connect to the USB, it fails to connect. In device manager and Ports it says - "Please install corresponding PL2303 driver to support Windows 11 and further OS"

I have tried the installer that you linked and it is not solving the issue. I have installed, and from the installer done a complete uninstall/reboot, then install, then insert the device.. Every time the driver that is installed is ver 3.9.1.0. There is no option to roll back any further. The device continues to not function, and in the device manager the heading only reads "PL2032TA DO NOT SUPPORT WINDOWS 11 OR LATER, PLEASE CONTACT YOUR SUPPLIER".

I've read through this whole thread (and a few others) and everyone is saying to go get the driver from the prolific site, although I think that's now been taken down, as every link takes me back to the site index. If I search on their site for drivers, I can go to the info page/brochure for the pl2303, but if I even click their own link to the drivers page it takes me back to the site index. I've also tried using a VPN to pretend being in the US, as I'm in the UK, no luck!

I had similar problems with PL2303 issues (Prolific USB to Serial Drivers) Windows 11 for communicating with the CELESTRON NEXSTAR+ & STARSENSE HAND CONTROLLERS. Standard USB-A PORTS on computers did not recognize the drivers and were unable to establish a connection using for connecting the USB-A to USB-B Mini Lead to the HAND CONTROLLERS.

The PL2303 v408 Driver for Windows 11 problem was immediately solved when I attached a USB-C Adaptor with USB-A Ports to the same computer and connection of the same lead to the CELESTRON NEXSTAR+ & STARSENSE HAND CONTROLLERS. The USB-C Adaptor & USB-A Ports were immediately recognized by the Drivers and allowed perfect communication.

Excellent advice. I turned your instructions into a PowerShell snippet with makes this procedure pretty quick. Just set the path to the driver files.

Attached is a screenshot of my Device Manager with 2 programming cables plugged in. (1 Yaesu, 1 Baofeng).

At the moment you see the port (com3) within the device-manager, the drivers should work. (Some minutes after connecting the XGS via USB windowsupdate installs the drivers for me)

38400 is the speed i used too. After hitting the keyboard, I see something from the device.

The XG is running? You are able to ping to or through the XG?

In response to your questions:

The XG is running? You are able to ping to or through the XG?

The XG is running, its LEDs indicators are OK and we have some internal servers wich we access from the WAN through the Sophos that are currently available.

BUT... now the terminal is not regonizing the admin password (its the same I always use to log in as admin at the webadmin console). Do I have to use another password for at the console terminal? Any advice?

We just got two new XGS firewalls (delivered with 18.5.0 GA). I couldn't get a console connection on either. Upgraded to 18.5.2 and both connect fine. Also note, the actual port number may be different on your computer. Even on the same laptop, one of the XGs came up as COM3, the other XG came up as COM7.

The error you're getting is probably because Windows needs drivers for the COM port. I thought Windows 7 was fine, but maybe 64 bit isn't. Try following the Windows 8 instructions on this page and see if it helps...

Tried that a few times. I had it working a few weeks ago but it took me a day and a half to find some driver file that happened to work. Then my 3D printer showed up and I wanted to reset the windows computer to its factory state to get all the slow BS off of it. (my normal computer is a Chromebook) I sure wish I saved that file first because I can not duplicate whatever I did. Pulling my hair out! Its a HP laptop with Windows 7. Few years old..... Trying to re-flash with the network drivers.......

Use the instructions Gordon has supplied - however you will have to go in to device manager and access the "drivers" tab for the unknown com device and manually point to the file that is unzipped with the driver download, it was greyed out for me when I tried to update drivers via the "devices and printers" window.

Guys can someone please post a YouTube video from the ground up on either Windows 7 or 8. I do now know what I am missing and this is just getting aggravating. I have tried 3 different computers. I have installed windows 8 dpinst_amd64.exe. Connected on the top left of the HY32. In boot mode. Thanks

If you can't flash Espruino, the problem is probably that the board you have uses a fake Prolific PL2303 chip for USB. Prolific got fed up with all the clones of their chip, and tweaked their drivers so that they don't support it.

Yeah I finally got it to work. There are a few issues I had. On these boards I had to use the TOP RIGHT usb port. When I downloaded the ST Flash Loader Demonstrator I was trying to get the STMicroelectronics com driver to work and it did not at all. The driver that worked best for me was this Prolific Driver. Its a Prolific Driver Version 3.2.0.0 and is dated at 7/31/2007

You have to manually update the Driver. Similar to this video

although after that driver was installed on my Windows 7 computer it was named plainly as "USB-to-Serial" until I re-updated the Driver.

The prolific pl2303 cable is not recognized by the USB of my router using openwrt, I already have the package kmod-usb-serial-pl2303 - 5.4.89-1 installed, is there any additional driver or package to install?

I just have checked all USB ports and connected devices to all of them and I had no problem, I believe that the point is any some additional driver, or change the prolific pl2303 wire, but if in the reserve scenario works it seems that the clue is the first one

To all, if you buy a new USB-to-Serial adaptor, do not get PL230x and FT232, because there are many fake ICs on the types, normally they work on Windows ok for a simple use, but still come with some driver issues comparing the original.

Disconnect the null modem wire. Plug only the device that you think is a PL2303 into the router USB port (again, with nothing connected to the serial side). Check the router log. If it still says FT232, that is the chip that you actually have and the simplest thing to do would be to install the appropriate kmod. The two drivers can be loaded at the same time and they will attach to whichever chip is plugged in.

- I recently had a query regarding the ELM327 in its USB version. That person did not get the computer to recognize the ELM327 device, his computer has a windows 10 64 bit installed. Fortunately I have at my disposal 3 computers with Windows 7 and 2 with Windows 10.I started testing on my usual computer and where I had already used these ELM327 devices without problems. To my surprise, out of 10 I tried none worked. In all cases, in the device manager, a yellow error signal appeared on the COM port where the device was connected.

- As always I hope that Windows give me some useful information about the problem. So went to check the error code and cause message. And as always I stay as I was before reading that information. It simply informs me that a non-existent device has been specified, indicating error code 10.

- Immediately tested the same devices on the other computer with Windows 10, with the same result. After testing every one on the computers with Windows 7 installed and checking that they all worked perfectly I came to the conclusion that it was due to a compatibility problem with the operating system. After searching for information on the internet about it and reading lots of tips indicating downloading the latest version (without result), disabling some specific devices in the device manager (without result) and the like, I came to the conclusion that I had to start from the beginning.

- The first thing would be to find out what chip for the USB communication had built-in these ELM327 USB. After dismounting one of them and see the inscription PL-2303HX on the serial communication chip, I went to the manufacturer's page where I found the following driver information for this chip. They indicate that it works for PL2303 HXA, XA, HXD, EA, RA, SA, TA and TB chips, with the important caveat that it does not work for Windows 8, 8.1 and 10 for the PL-2303HXA and PL-2303X versions that are EOL (End Of Life). What comes to say more or less they are no longer manufactured and have been left to give support in the latest driver versions.

- As the inscription of the chip is PL-2303HX now had to know if it is the HXA (without support) or the version HXD (new version that does have support). In the chip itself, after that inscription appears another one of the following style LFXXXXXA, where the X are numbers from 0 to 9. This code identifies the revision of the chip and the last letter, A in this case, indicates that it is the Chip PL-2303HXA. Just the one that has been left without support for windows 8, 8.1 and 10 in the latest versions of the driver.
