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 bought an Arduino nano clone on ebay. It came with PL2303 instead of FTDI chip. When I plugged it in the usb port, it gets recognized and win 8.1 installed a driver automatically. But the driver can't start.
I can't even find where the pl2303 driver install program unzipped the drivers. A PL2303 driver IS installed after I plugged in the Nano but it shows error messages. The manufacturer specifically says PL2303 HXA is obsolete and has no win8 driver. Have you tried it yourself?
I haven't tried but I have used that way to install some old drivers. I don't think it is a hardware limitation, it might be something like chineses cloned that chip too much that prolific stopped supporting these old versions or something like that.

That was in my thoughts too. Make it obsolete. If you have the driver, can you tell me the file name. I just couldn't find where the install program unzipped the driver so I can't specify where to find driver
Not really an argument, when you can't afford to buy everything genuine ... well you just can't _o - pretty much the same thing as saying "another good reason to only buy industrial-grade laser CNC machines / 3D printer / insert really expensive device here".

- 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.
- The possible solution was now to find an earlier driver that would support the PL-2303HXA. After much searching I found an old version for Windows Vista (version 3.2.0.0) and that, theoretically, could support the version of the chip of these devices. Also in both versions, 32bit and 64bit. You can download them below, in the download section.
- Keep in mind that the driver must be changed in all USB ports where the ELM327 device is connected, because when you connect a device to a USB port Windows will always choose the newest driver. Which in this case is a fatal error. So when we change USB port will have to repeat the change of the controller from step 5.
- Finally we have found more drivers from older versions, we put them in the download area, maybe someone need it, you never know. The ones mentioned in this article (versions of 32 and 64 bits) are: "PL2303 USB driver Win Vista 32bits" and "PL2303 USB driver Win Vista 64bits".
I have several serial adapter CH340 or CP210x with a small problem which is that with these the server boxes are blocked at startup if the adapter is connected
By cons I have a very old PL2303 adapter that works but the latest driver is no longer compatible with Windows
what could you advise me?
Problem is by exemple a CP210x (
cneutec.com CNT-0038 ).
When i plug the 3 wires to my wr1200js cannot start
When i plug the power supply. not serial port connected i connect only after the serial port.
CP2014 or CP2012N
pololu.com Pololu - CP2104 USB-to-Serial Adapter CarrierThis USB-to-serial adapter lets you easily connect a TTL serial device to a PC by acting as a virtual serial port. The board is a Micro-USB carrier for the Silicon Labs CP2104 USB-to-UART bridge that provides access to all of its control signal pins...
The majority of FTDI FT232R(L) chips will be fakes so you'll be safer to go for another model if you want FTDI. The same goes for Prolific PL2303HX/HXA, go for PL2303TA instead (not sure if there are any known fakes of TA however).
they work great on linux and fine on windows once setup ( read before you try on windows! )... just be aware many schematics aren't perfect when it comes to 3.3v being 3.3v so if you have a particularly valuable or sensitive board... i'd advise a some leveling on the tx or vin > LM11173.3v > vcc.
Without problem as i described it to know that with several different adapters when the branch plugs the adapter and that puts the power supply then the starting of the box is blocked. For this to work I do not have to connect the USB adapter before starting the box except with a very old PL2303 adapter which does not pose this problem.
