Presumably Faulty - will have to return it!
I purchased this USB to Serial RS232 Adapter to connect with my serial connected Seiko Smart Label Printer Pro (SLP2000). I already have a Prolific based NEWlink USB Serial Adapter which works with my label printer. However, upon reading many of the good reviews here I decided to purchase the StarTech.com USB to Serial Adapter mainly for the COM Retention feature (not present on my NEWlink), but also because it uses the FTDI USB UART Chip - purportedly more stable amongst other things. However, despite spending considerable time I have been unable to get it to work (unlike my Prolific NEWlink) with my label printer. It assigns a USB-Serial Port okay, and the label printer finds it alright, but it will not print labels out no matter what I try (including reducing the Baud rate ). I've concluded that it must be faulty and will have to be returned. Ironic that, in this particular;ar case, the Prolific based NEWlink just works out-of-the-box whilst the better spec and more expensive FTDI based StarTech doesn't. Have to go back to using the NEWlink Adapter - at least it actually works.

Reviewed in the United Kingdom on 27 July 2013
Size Name: 1 PortStyle Name: SingleVerified Purchase
Having tried cheap versions of a USB to Serial converter, which were nothing but grief, I bought this entirely on the strength of the unanimous 5 star reviews. I have only had the product a couple of hours and it is already in and working having successfully connected my Palm Vx to a USB port on my XP pc.

There was a minor glitch in loading the driver, which under XP did not install automatically as others have found. Fortunately, there was documentation in English with the product, which helped. Had to look a couple of directories beyond where the doc suggested, but it finally installed OK. Restarted the machine as requested and, bingo, it works perfectly.

Let's hope it stays that way - the previous adapter packed after a few minutes - but for now I have no hesitation in adding yet another 5 * rating. Although much expensive than the previous adapter, which cost £2.30, I wish I'd gone straight for this one. It would have certainly saved me a load of time, effort and stress trying to figure out why it wasn't working. In this case, you certainly do get what you pay for!

This natty adapter provides my newish pc with a serial port via a USB slot; It was detected by WIndows 8.1 by plug and play and I was not prompted to load the driver so I didn't.

My pc tells me it's working perfectly but sadly the obsolete tablet I'm trying to connect (discontinued 1998!) still wouldn't work, but I can't blame the adapter. I guess I was just being optimistic...

I needed this adaptor to connect my GoTo astronomical telescope to my new desktop to control it from there. My last computer had a 9-pin port so I just had to plug it in, so I thought that any adaptor would do, so I bought the cheapest I could find. That was a mistake! I was surprised to discover that it needs a driver, and also the one I got seems to be incompatible with windows 8, as far as I could tell from the incomprehensible Chinglish instructions.

My only complaint is that the instructions say "When the New Hardware window appears....", but it didn't appear. I was unsure what to do and so I contacted their technical support and was quickly able to chat online with someone who quickly helped me to find out that the device was working correctly, and identify the port number. With that information I was soon working the telescope from the computer.

It is definitely worth paying a little extra for the quality and support, penny-pinching is false economy.

5.0 out of 5 stars USB to Serial Adaptor RS232 port DB9 (male) with chipset FTDI - FT232RL
Reviewed in the United Kingdom on 11 July 2017
Size Name: 1 PortStyle Name: SingleVerified Purchase
I bought this because I have a Ross Tech OBD II connector for VW car diagnostics that has a Serial Port (RS232) and unfortunately the lap top I now have does not have such a port. I looked at lap tops that have a serial port and they start from £1,800. I decided to buy a device to convert from a serial to USB. The device I needed was with a FT232B or FT232R chipset. Research came up with a few and further research concluded that this would be the best quality, though not the cheapest.
I have a laptop with Windows 7 Ultimate (64 bit) and it recognised the device. I just had to do into System properties>device manager>ports>USB serial and then go into properties and change the COM Port number to "com 4" and cnage the "latency time" to "2" as per instructed by Ross-Tech.
Works perfectly !!

I am using it to connect my serial port weather station to a Mac Mini.

Il prodotto è di alta qualità e funziona perfettamente; ha il chip originale FTDI che viene riconosciuto immediatamente dal PC (lo uso con Windows 10 Pro) e andando a verificare le proprietà del dispositivo in gestione periferiche, si può constatare che le opzioni disponibili sono quelle avanzate che solo quel chipset ha.
Insomma, nulla a che vedere prodotti simili di costo magari molto più basso ma che poi fanno penare per l'installazione dei driver!
