Does not come with the 3 foot cable
I didn't get any further than taking this out of the envelope they sent it in to realize it did not come with the 3 foot USB cable. I needed to use this to connect my laptop to a fire panel and the extra 3 foot cable would have made this the perfect length for what I needed. I never unboxed it because it was not what I purchased. It may work for some, unfortunately it wouldn't work for me.

5.0 out of 5 stars Great adapter
Reviewed in the United States on October 16, 2014
Verified Purchase
Works perfectly for using old serial equipment over USB. Works great with Windows 7 64-bit.
Also works with Windows XP running as a virtual machine inside VMware Player.

This device uses a GENUINE FTDI chip, so it is not affected by the newest drivers that disable counterfeit chips.

5.0 out of 5 stars Does the job!
Reviewed in the United States on November 27, 2012
Verified Purchase
I bought this because I was having performance issues with another brand of adapter. I had read the reviews on this unit and it was touted as one that was highly compatible and trouble-free. This unit immediately cured all the issues I had been experiencing with my previous one, and I am extremely pleased with this unit. Skip the cheapies and go straight for this one if you want to minimize adapter-related problems.

4.0 out of 5 stars Works with Mac Lion
Reviewed in the United States on April 21, 2012
Verified Purchase
This uses the FTDI chipset which is the only one which will work on Lion. The prolific chip
used in some other adapters just doesn't work with Lion. A half star off for software on mini cd - not cool for Mac laptops. Another half star for the bulky connection. It blocks the other USB ports. I had to get a short USB extneder cable to use my mouse. Otherwise, with the right drivers, it DOES work with Lion.

5.0 out of 5 stars Best USB to RS-232 Adapter found
Reviewed in the United States on May 24, 2011
Verified Purchase
I tried 3 or 4 other manufactures of USB to RS-232 adapters and all had issues with the software I was developing. Some USB to RS-232 adapters even blue-screened Windows. This is the only adapter that worked flawlessly. The USBGear device uses the FTDI chipset and has certified Windows drivers. I highly recommend this USB to RS-232 serial adapter.

5.0 out of 5 stars Perfect on Win7 64bit
Reviewed in the United States on November 1, 2011
Verified Purchase
Plugged it into my system and it has worked like a champ.

Before you use the adapter you'll want to run "Windows Update" off the Start menu. For Windows 7 you won't need the mini CD-ROM that comes with the adapter. Run "Windows Update" two separate times because there are two things Microsoft wants to install.
- FTDI - Other hardware - USB Serial Port
- FTDI - Other hardware - USB Serial Converter

After those two software updates are installed you're ready to use the adapter.
This unit also came with a very nice shielded USB extension cable too. I'm using it for a very old Garmin GPS device. The Garmin software found the serial port very easily.

5.0 out of 5 stars Excellent!!!
Reviewed in the United States on September 11, 2011
Verified Purchase
This serial usb adapter that has the FTDI chipset. The Prolific chipset adapters do not work as well as these. This worked the first time I pluged it in perfectly. If you are having trouble with the prolific chipset adapters, buy this one. I don't give 5 stars much, but this one is a 5 star item! The price is a little high, but the free shipping makes up for it!

The drivers on the CD it came with i'm sure are fine, but they may be 1 rev behind. I got the latest from the main website.
