StarTech.com 17in (43cm) 1-Port USB to Serial Adapter Cable, USB-A to DB9 RS232 Adapter, Prolific Chipset - M/M

Had an old one from a different manufacturer and was having a ton of issues finding a driver that works with today's computers. Got tired of looking and decided to just order this one and it worked right out of the box. Zero issues.

These have been my goto option for RS-232 connectivity for a number of years. I have used dozens of these with much success on Windows, Linux, Mac and FreeBSD over the years.On the Windows platform, the driver in included with the operating system from Windows 7 and beyond, so they “just work” on anything you’re likely to use it with today.I am NOT a paid reviewer or been given freebies. I am just a customer trying to help others. I hope my review helps you make an informed purchasing decision!

Easily one of the most compatible serial to usb adapter cables you can buy. If you want to know that the cable is good 99.99 percent of the time this is the one to buy.

This is decent and the price is good. This has not been 100% on picky devices. Although it is ok, I would recommend the Keyspan. That has been the only device that has worked on all hardware I work with. It is required or recommended at many training classes I have been to.

It's being used with a dell R7620 and does the job. It's important to follow the install instructions carefully.

I have been using several of these adapters quite successfully for several months, but then I upgraded one of my PCs to Windows 11, and the adapter no longer works. In device manager there is a message saying "Please install corresponding PL2303 driver to support Windows 11 and further OS." I have searched, there does not appear to be such a driver available!

It is plug and play,and it works very well. The only bad thing is it generates alot of RFI in the 100 to 300 mhz range.I use it to allow my tablet to control the frequency of two radios, when I am using the amateur radio satellites. I have tolisten on 145 -146 mhz. Go up on 445-446 mhz. I am working on shielding them to reduce the noise they create, thesignals from the satellites are weak. Sometimes I can't hear them due to the RFI created. Tony

This has the real deal chip in it and worked on Windows and linux immediately without having to install a 3rd party driver.
