Customers are saying

Customers have good things to say about the USB to serial functionality, compatibility with various operating systems and devices, and the ease of use of this adapter cable. Many appreciate its quality and durable construction. However, some customers point out that the cable length is short, and that the lack of included drivers may pose a challenge for some users. Overall, the positive feedback on functionality and ease of use outweighs the concerns about cable length and driver support.

    Needed to connect to a router that used Ethernet. Computer did not have a 9 pin port, so bought this to convert USB to 9 pin. Worked great. Do not need it often, but if you do this is it

    I needed the adapter for my Macbook Pro, I run Windows 7 Pro in a Virtual Machine using VMware Fusion. I have noticed that with Parallels and VMware Fusion that when you attach a USB device to you mac and tell your virtual Machine to Capture it for the Guest OS to run it is hit or miss on finding devices that will work properly that way. When I looked on the back of the package it said that this adapter suports OS X and Windows I bought and tried it and it works great.

    Needed one of these in a pinch, no one but best buy had one in stock. I'm a HVAC/Chiller technician, mine broke on the job and I needed one to hook my laptop up to a chiller for programming. It did the job. Cable is little short but USB extension work well with it.

    Having an urgent need for a USB to RS-232 DB9 adapter, the helpful Best Buy folks quickly found this easy to install and use one at my favorite go-to place for electronics, accessories and so much more. There was no delay waiting for drivers to install, nor any problems operating with the devices connected to it. Thanks Insignia and Best Buy!!

    I deal with older PC’s and electronics. I needed a USB to 9 pin serial adapter. Could not believe Best Buy still carried these. I bought all 4 they had left. Got me out of a jam.

    Bought one at the last minute to troubleshoot a Cisco equipment issue and it worked like a charm. Insignia doesn't have the latest drivers, but you can search "PL2303 RS232 Driver" to hopefully find it on Prolific's site.

    Awesome comptablity and no new for driver discs! Only 1 tiny complaint it is very very short. So you will most likely need a serial cable to extend this which is cheap.
