One of the cheaper adapters I purchased would only work with drivers that were designed for Windows Vista, and even though I was able to make it work by installing that driver on my Win 7 box, as soon as I unplugged it and plugged it in again, the Vista driver was automatically over-written by the Win 7 driver, and the adapter stopped working.
One serial device I own (a security alarm controller) came with the recommendation to use this Keyspan adapter for USB connections, and I have found that this is completely true. No other adapter works with that device.
An additional benefit of the Keyspan device is that the USB cable unplugs from the adapter itself - using a standard USB cable that can be obtained in many different lengths. This can be a big help in managing cabling between the adapter and the computer.
I've had a variety of USB-Serial adapters, and the mixed bag of results, makes this one a refreshing change. It came with software, but I didn't need it. Just plug into the USB port, and it downloaded the proper driver straight from Windows Update. It just worked!
It's a sturdy construction, and comes with the USB cable. The cable isn't incredibly long, so if you need to reach, you might bring another for longer distances. There is a light on it to let you know when it's connected, which is very handy, and the port that is created on the computer shows the Keyspan, so you don't need to pick trial and error until you have the correct port. This is powered by the USB port, so you do not need any kind of additional battery.
Very happy with this, and I strongly recommend this to anyone who has a need for a USB to Serial Port adapter.
UPDATE: As I feared, quality control has indeed slipped since Tripp Lite took over Keyspan. I've now had a second adaptor fail in less than a month. One failing can be a random failure - two failing is a sign something's wrong at Tripp Lite, hence my revised one star rating. Unless you can round up a "real" Keyspan adaptor (pre-Tripp Lite), I'd give this one a pass. Too bad, because Keyspan made great adaptors.
For the price point I would have expected a much higher quality product, my coworker led me on to this product however he had a much older version.
The difference between them were astronomical.
1st, the item I received did not match the picture, mine is a much cheaper looking knock off, not sure how that happened.
2nd, as soon as I plugged in the usb into the adapter and took it out, it broke, just like that. in under 1 minute my brand new device turned to crap, the usb port is so loose and cheap it amazes me they get away with it.
3rd, it drops connection consistently, if you are using hyper terminal or other similar programs (putty) you will relieve and error and have to reopen the session which is the most annoying thing in the world when trying got configure a switch or a node.
Overall bad experience, product seems WAY to overpriced for the cheap piece of garbage you get for it, I would pay 5 dollars for this and be happy but 20 dollars plus I don't think so.
This product is the perfect example of made in china at its finest and I would avoid it, find something cheaper and better.
