Works fineJun 09, 2008
By Harvey Sugar "Embedded software engineer"
I've been using this USB serial interface for a couple of years now. I've used it under Windows XP, Fedora and Ubuntu Linux. The Windows XP drivers are available on Keyspan's website. Fedora and Ubuntu (except version 7.10) include the drivers in the standard distribution.

The serial interfaces are solid, providing good RS-232 drive levels. The interfaces can also handle decent bit rates. I've used it up to 115200 BPS. It's also very convenient the way it is packaged. Especially in embedded systems programming, it's nice to have four serial ports right on your desk top with just the one USB cable running to the computer.

Good News - Tripplite/Keyspan has 64bit windows driversMar 24, 2010
By Howard Zuckerman "Howard"
This is the absolute best USB to Serial Comm port adapter.
You'll never need to unplug and replug it in.
You'll never need to go into Device Manager and change the COM port number.
It is a good performer and works well.

Tripplite/Keyspan has 64 bit driver for windows XP/Visa/W7.

I have used this device on 32 bit Vista and on 64 bit Vista.

Reduces ClutterJun 20, 2008
By Dan M. Beadle "Entrepreneur"
I have used Keyspans individual port adapters for several years. They work flawlessly and are quite fast. I do a lot of work on high speed serial devices running without flow control. The devices keep up.

I found that I often had 4 single Keyspans cluttering my desk. I wanted this device. When I finally found it, it was a no-brainer. It works flawlessly. (I had hoped it would be less expensive than 4 singles - and it is - just a little.)

A nice little benefit is I use their static mapping tool to make the ports appear as COM11 thru COM14, eliminating past confusion about which port goes with which device.

Serial is officially a legacy device. New PCs don't have serial ports. But, if you have a lot of serial devices to manage, this is a great way to simplify cabling and management hassles.

Great piece of equipmentSep 12, 2009
By Sojourner Truth "Sojourner Truth"
This thing works. I am an amateur radio operator (ham operator) and I used an old 486 computer to run several communications and logging applications in my ham station. The applications control my equipment -- changing frequency, logging contacts, sending/receiving Morse code, teletype, and other modes. When the old computer crapped out I had a real problem: The old computer had lots of COM ports -- new computers have only USB ports. I purchased two different USB-to-serial adapters -- neither of them worked reliably. I was a bit reluctant to pay the price for this one but, after reading the comments, I bought it.

This thing is great -- it setup in seconds. I connected my equipment to three of the four ports, set up the ports in Windows XP Device Manager (had to set the baud rate), started my old applications and everything worked perfectly.

Keyspan usb-serial adapters superior to othersOct 09, 2008
By A. Smith
I bought both the 4 port Keyspan USB-serial adapter and the single adapter after trying IOGEAR versions. I had various software issues with the IOGEAR when switching ports or plugging in different devices, as it would constantly assign a higher port number. I can only think it is a result of its incompatability with Windows XP (in the fine print of the instructions). The Keyspan USB-serial devices have worked extremely well and can easily switch ports. The difference is huge.
