Summary: Yes, this is the special cable one needs to CONVERT from PS/2 keyboards to USB...a plain ol' (cheaper) adapter cable will not due. This worked perfectly, even though all I use now is one of the PS/2 connections.
Summary: Works great for connecting my Windows 7 64-bit HTPC to my Nuvo Essentia E6G whole-house audio system. My only complaint is that I had to rip out the connector posts since I wanted to connect it directly to the Nuvo. A little time with a vise-grip fixed the problem though.
Summary: Garbage. Blues screen twice a day. I using it with Win7 64bit latest driver from their website + putty. If you have lots of text output in the serial console, better pray well, otherwise you'll get blue screen.
Summary: The Uniden BCD396XT programmable radio requires a cable to connect to your computer, but they imply that you need to purchase a special $30 USB cable. As has been pointed out by other reviewers, that radio already comes with a serial cable, and all you really need to connect to a modern, serial-less computer is this relatively inexpensive TRENDnet serial-to-USB converter cable. It works just fine, and costs one third of the USB cable price.
Summary: Very happy with my purchase - will be buying more of these! Picked this up for a computer interfacing, data acquisition and control project with Python in Ubuntu Linux and Linux Mint. Plugged it in and '/dev/ttyUSB0' appeared immediately! Wired to a BB400 Solderless Plug-in BreadBoard, 400 tie-points, 4 power rails, 3.3 x 2.1 x 0.3in (84 x 54 x 9mm) by soldering leads onto a DB9 D-Sub Connector Solder type Female with a Hakko Soldering Station, FX-888 and some Kester 44...
Summary: Just wanted to confirm for others that it works without modification on 64-bit Mac OSX 10.7 Installed the drivers from the .dmg on the disk, rebooted, ran "screen /dev/tty.usbserial 9600", connected my serial device, and voila.
Summary: I recently purchased this to connect a serial output wideband O2 sensor from my car to my Windows XP laptop. The adapter includes a CD with the drivers, which it instructs you to load before plugging the adapter in. I would suggest ignoring the disc. The drivers are generic to the PL-2303 format, and I believe already loaded in Windows. Running the driver install resulted in my computer asking me if I wanted to un-install the driver that was already in place. No need.
Summary: This does not work under Windows Vista 64-bit. So I installed Windows XP as a virtual machine and got it working by sharing the host USB ports. Controlling a Shure DFR 11EQ and it works great.
