Driver needed > driver cant be downloaded
The wbesite in the manual for drivers is wrong, but found it eventually. Otherwise works just fine.

Plug and Play with Exceptional Quality
I needed a USB to RS-232 Male serial cable for some programming at my job. My initial thoughts when unpacking the cable and seeing a CD to install drivers was, great another piece of software on my laptop that is already loaded with work software. Because I did not want to install another driver on my laptop, I decided to try the cable without installing the drivers and it worked without an issue. This is not to say there may be devices that communicate better with the proper drivers installed, but for my use, it was plug and play. I was using Windows 10 as the operating system. You will most likely need to install drivers to work on older operating systems. Overall the quality of the cable is exceptional and exceeded my expectations. Great cable for the price!

Current version does not appear to work on Macbook Pro with M2 Silicon
I have purchased these - they came with the PL-2303 chip inside and work just fine on my Mac, both M1 and M2. Also on my PC (windows 10). However I purchased 1 recently and it is not recognized by my Mac (M2). It does work on my PC, but the mac won't recognize it. Downloading the newest drivers didn't change that. From the Macs System Information/USB listing... the old, working version of this cable shows a Product ID of 0x2303, vendor Prolific. This new, non-working cable, shows up as Product ID 23a3, vendor = Prolific. I'm guessing the product ID is not matching the driver for some reason. I've done some searching around the internet and haven't seen any references to this.... other than the general advice to get an FTDI chip cable and not use the 2303 cable. The product information does not mention this issue - everything just says compatible with Mac.

Does not work with Windows 11
Doesn't work with windows 11. Tried downloading drivers from the website, but no success. Ended up buying TRENDnet USB to Serial 9-Pin Converter Cable, Connect a RS-232 Serial Device to a USB 2.0 and it worked perfectly no need to install any extra drivers with Windows 11.

As an old tech guy I still have some serial devices, but none of my computers have serial ports any more. This works perfectly and is auto detected.

Super kabel van goed materiaal en maakt gebruik van de Prolific PL2303GT chip. Werkt goed op Windows 7 tot er met 11!!! Wordt met automatische update voorzien van de juiste driver! Op diverse apparaten getest en werkt uitstekend:)

Win11で問題無く使えました。激安(500円くらい)のケーブルだと三菱のPLCに使えませんでしたが 、この製品はOKでした。安価に購入できて良かったです。
