I had been using a Gigaware (Radio Shack) USB to Serial Converter to control a Celestron goto telescope under Windows Vista. When I upgraded my computer system to Windows 10 this device was not supported. I elected to give the TRENDnet TU-S9 (version 2) a try even though the package indicated that the device was supported only through Windows 8. The package info needs to be updated. The driver installed very smoothly and the Devise Manager identified the TU-S9. It now allows me to control the telescope flawlessly.
To test my luck, I installed the device on my wife's Windows 10 computer with the same result - works perfectly.
Don't let you heart skip a beat. With both installations the Device Manager showed the presence of the TU-S9, but when I clicked on "properties," the message came up that the driver wasn't present. In both installations, after shutting down Windows Device Manager and starting it again, it identified the presence of the TU-S9 (this time identifying the com port) and everything worked perfectly from there.

It does it's job for DB9 and even has an adapter for DB25

This cable works as intended, nothing fancy about it. It is just a 9-Pin Serial to USB cable, with a 25-Pin Parallel adapter. Didn't use the adapter, but I am sure it works fine. These cables either work or they don't, and there ain't much to go wrong. Installation was pretty simple, just had to plug it in, run the setup .EXE on the disk and it did it's thing. I needed this to link up to a Cisco 1710 Modular Access Router, and this worked perfect to bridge the connection from the Com to Serial cable over to USB since the computer I was using didn't have a Serial port. IMHO it was worth the $13 or so I paid for this.

FTDI + Signal lights = Flawless victory

After having struggled with corrupt data on my PL2303-based adapter every few minutes, I was suspecting problems with the target device, especially when the problem persisted after swapping adapters, reloading drivers, and trying a different PC.
Lesson learned: Replacing a Prolific chip with another Prolific chip isn't gonna fix it! Go FTDI or go home.
I bought (two of) these and the problems haven't come back; I can receive *megs* of text without so much as a hiccup. Logging over a long weekend used to be completely out of the question, now it's become routine.
And yes, the diagnostic LEDs are every bit as useful as you'd imagine, perhaps more so. Not only do they show you TX/RX and flow control, but they show you *when the port is open at all*, which is super handy if you've got multiple adapters plugged in and you've lost track of which COM port is which. Forget the paperclip loopback! Forget unplugging things to see which port stops responding! Just watch each adapter go all Christmas-tree when you open its respective port, and the mystery is conclusively solved.
My colleague has been using the other one to drive an old board plotter, which had exhibited inexplicable, random, and extremely frustrating bugs for months. Switching to a genuine FTDI adapter made everything suddenly work! The misbehavior is gone, the software doesn't lock up anymore, and we're back to making boards in-house instead of sending them out. Turns out the plotter wasn't bad after all, it was just a cheap serial adapter!
I'm never skimping on cheap serial adapters again.

Just works with Win7 64bit.

After reading about other USB to Serial cables based on the prolific chip and the problems people reported when using the cable on Windows 7, I decided on purchasing this. I hooked up my Cisco 2950 to my Win7 64bit laptop using this cable and it just worked. The OS pulled in the necessary drivers from Widows Update. Didn't need to use the driver disk that shipped with this cable.
The cable feels well built overall.

Cord length is great. This works how I need it to

Cord length is great. This works how I need it to. The hard part for me is that I have to use it with another cord and had to kind of jerry rig, with trial and error to get the tx and rx how I need them. Is that the fault of this cord or the other I don't know...
