    Driver is outdate, does not handle sleep/wakeup
    Used to talk to medical devices. The SYS file of the driver has not been updated since 2010. The overall installer says it is for Windows 8 and Windows 10 but it looks like Tripplite has not made any changes since Windows 7 was the current operating system. I inquired with Tripplite support about their commitment to the product and they said they would continue support (of course they did). If you put the computer to sleep and wake it up, the keyspan will always be unavailable, often requiring a full restart of the PC or an unplug-replug of the adapter to restore it. Some Win10 computers get a blue screen of death USB power state changes. It is a problem that the driver is from Windows 7. That driver model is deprectated. Tripplite has not re-implmeneted under the Win8/Win10 driver model to support all the new power configs. I really wish we didn't have so many of these in our customer's hands... we can be blamed for computer failures because of Tripplite's lack of dedication to the long-term improvement of this device.

    excellent adapter

    I tried other adapters to work with plc equiptment and had communication losses frequently. I bought this keyspan adapter and it has exceeded my expectations. I have not had one communication loss since I started using it. I highly recommend this product. Installation was a breeze.

    best I've found!

    I've used the USA-19HS for ~5 years with several industrial automation companies, really works perfectly with win7-win10 32/64bit. Highly recommended.

    Works as advertised

    This was recommended as one of the few reliable USB/Serial adapters for earlier windows systems. I'm using it to communicate between a ten year old XP system and a twenty year old industrial machine.

    Works Perfectly

    Works real well. I like the light that shows it's operating and the detachable cable which keeps it from getting frayed over time, which is what happened to my old device.

    Reliable and consistant Service

    This serial to USB adapter cable was bought as an interface between my laptop and controller on my model train layout. It was a model recommended by the manufacturer for this use. It works flawlessly and consistently. It is a little more costly comparing it some other manufacturer's models but in my opinion was worth the extra cost.

    Product works!!

    This product did what I needed it to do - connect an industrial device with an RS232 Serial Port to my laptop that only has USB and Ethernet ports. This should be a no-brainer, but I bought the Belkin Brand first, and it did not work. I borrowed the Keyspan unit from a business partner. It worked first time, so I bought one myself. I actually haven't used mine yet, only my partners. The huge problem with this kind of stuff, is that when the device does not work, you spend hours trying to make it work because you think you are doing something wrong - especially in the industrial world where you are learning your programming software as well. After many wasted hours I find out that my Belkin converter was the problem. The Keyspan unit solved my problem in minutes.

    Keyspan USB to RS232

    Actually seems to fully comply with RS232 standards, and so works with any remote RS232 equipment. Has associated test and setup options for getting USB behavior for multi usb ports. Many overseas and popular models, don't meet all voltage and current standards and thus aren't fully RS232 compliant. I am an EE and specifically wanted this item and was surprised to find it at Walmart since I consider it to be a technical niche item. JimD

    Keyspan High-Speed USB/Serial Adapter

    I've used this USB/Serial adapter on 3 different ham radios. Each ham radio is from a different manufacture and the USB/Serial adapter worked on all of them without a single problem. I use the interface to download updates to the ham radios as well as control them via my PC. PC OS; Vista

    1. It's been 1 year since you asked your question according to this site. I hope you found your answer already, but just in case. The USB cable is included. I'm not sure about stores carrying it. I ordered mine online.
