Check the FTDI Version
Unfortunately, the chipset was NOT compatible with our needs. Newer Serial-USB adapters with current-version FTDI chips are now the standard. Older versions and other manufacturers are filled with problems with driver incompatibility.

Great Adapter for computers without Serial Ports
Purchased the Gearmo USB to Serial DB9 adapter to connect printers to laptops. The setup is easy and other than sometimes pulling out of the USB slots they work great.

This want packaged in a box, like the photo shows, but it includes everything is supposed to.
It appears to be a durable and quality item.

I bought this to program my Kenwood D710 but haven't had the opportunity yet. I'll update this review if there are any issues.

Great on OS X
Surprised me that it worked on OS X Yosemite without installing any drivers. I've used other serial USB interfaces (for arduino and similar projects) that required some tinkering to get working. This was literally just plug in, attach other end to Juniper console, and "screen /dev/cu.usbserial-xxxxx 9600" and I'm on the device.

Would not buy again.
Bought it because of the reviews. It does work with Windows 7 64 bit so it gets more than 1 star.

But...

It hangs the usb port when it falls out which requires a reboot to get the port back.
It fall out often because the steel shell does not hold it in place.

I bought 3 in Nov 2012, one has stopped working, the plastic over the usb connection fell off on another, one still works but the the problems listed above.

USB to Serial Adapter, windows 7
I had a USB adapter that worked on windows 7 last year. When I hooked up the GPS this year it would not work. I was told by a techie that if I had automatic windows 7 updates, which we all do, that the old adapter would not work and I would need a 64 bit for windows 7 new adapter. I got it and loaded the program and it worked!! Who would have thunk it?

Does exactly what I needed
I purchased this product to connect my Lenovo T420 to Cisco devices through the console port. Unfortunately, the newer ThinkPads do not include a serial port, even on the docking station. I am not sure why Cisco hasn't kept up with the time and changed their cable to terminate to USB or include an adapter from serial RS232 DB9-F to USB, because it cost me time to get what I needed.

I got on Amazon and searched for a product that could provide the serial to USB conversion and came across this one. I read the reviews and heard a lot of positive feedback. I went ahead and ordered the device.

The shipment,was delivered on time. I opened the box and saw the part and a drivers CD. I am running Windws 7 64- bit, so I was concerned I might have to use the disc. But I plugged the adapter into the console cable and then plugged the console cable into the Cisco device, and finally the adapter into my laptop. Windows automatically found the,drivers without needing the insertion of the CD. I fired up a PuTTY session and had restored console access.

I was very happy with the product since it did everything it said it would do and I never had to search for the correct drivers on the CD. I am also happy with the service, as we received everything in the timeframe that was given to us at the time of purchase.

WORKS GREAT 64bit windows 7
WORKS GREAT! on my windows 7 64bit computer, it recognized and installed it threw windows update automatically with out need or use of the cd. i did have to go into "device manager">"ports"> and click on the properties of the new device and change it from com3 to com1 for it to work properly with my palm device. otherwise it was stress free and easy to install even on my windows xp laptop, on the windows xp lap top running 32bit, it went threw the manual install, which followed the instructions provided in the pdf file on the cd. the windows xp computer was a breeze to get it installed on, a few clicks and it worked with my palm desktop software. no need to change it threw device manger from com3 to com1, on xp no settings needed to be changed in device manager, but on windows 7 64bit i did have to go into device manager to change it from com3 to com1 then enable com1 on my pamm desktop sync icon .

no complaints. its well made and worked effortlessly on multiple computers.

Works great with Windows 7 x64 bit
Ordered this because my old USB to serial cable didn't work with Windows 7 64 bit. This one does. I bought it to use to program AVR microcontrollers on an Atmel STK500 board. It works perfectly. Didn't even need the CD as windows installed the drivers automatically. It is nice and short--no extra cable coiled up on my desk.

As advertised! No more BSODs
As someone that still needs to use serial console cables from time to time (accessing Cisco equipment), I needed something that wouldn't send my Windows 7 x64 laptop into BSOD hell. After some googling, it turns out the FTDI chipset works fine and doesn't cause issues with Windows 7 x64.

I've tested this extensively while setting up and staging equipment for labs and customers. What I do notice (in putty) is that sometimes scrolling or pasting in a lot of commands can cause it to just stop working. It's easy to just close the session and reopen it, but it's annoying if you're working with a large script/configuration. I'll try secureCRT later to see if it's just a putty problem.

Overall I'm very happy with the purchase since it allows me to do what I need to do without breaking my laptop =).
