USBGear 12 inch USB to Serial RS-232 DB-9 Pin Adapter with FTDI Chipset for Windows 11, 10, 8, 7 and Mac Systems - Use for Laptop Serial Port, PDA, GPS, Modems, Routers and More

I liked that Windows 10 recognized it instantly and loaded drivers for it, the disc was not necessary. This adapter is mechanically exactly the same as the COM connector that is found on the XP and older computers. I plugged my radio programming cable into it and the computer found it in 2 seconds. Communication to and from the radio was faultless. I don't know why other reviewers are complaining about the female threaded studs, perhaps they don't know what a proper COM jack is supposed to look like? I did notice some other devices similar to this one that have the correct male pins but have the hold down bolts of a female plug instead of the nuts found on a jack, but those by definition are not standard COM jacks, but are instead a mechanical corruption of the original concept. I find nothing to dislike with this device other than perhaps it could use a bit longer wire.

A very useful device. Incredibly tolerant of everything I have subjected it to. Worked flawlessly with the drivers included (on a 7cm CDROM) on Windows XP and XP Pro. Ubuntu recognized it with native drivers. Works with arbitrary baud rates correctly under Windows but Linux takes a bit more work. On Ubuntu it does work correctly with standard 16550 UART speeds right out of the box. Neatly assembled and sturdy for its size. Good quality receptacles on both ends (USB and DB9). Recommended for the price.

Finally found an adapter that works with Windows 11! Note, it is a bit tricky to get the driver working. The website is not much helpful, but I managed to get it working after several attempts.

I struggled with this usb serial adapter for hours with Windows 10. Used the included disc with drivers. Never could get it to work. However, with windows 7, it was easy. Plug and play took 10-15 minutes. Did not need driver disc. Then it worked like a charm. I was able to download and install new firmware for my ioptron telescope mount.

I purchased this adapter Feb 2024 and it worked for a few times which was when the lights would blink when I would connect it but now it no longer works and the lights don’t come on anymore. How can I return it? Is there warranty ?

Half the price of going through steno equipment providers!! I still use an old laptop with Windows 7 which I will never give up for my particular business and it was no problem at all connecting with the drivers.

I needed the USB to serial for both a Windows and MAC, fortunately it worked on both systems without a problem, however, if I had needed to install any software on my Macbook I would have had a problem. The mini CD with the software cannot be loaded in via a Slot CD reader. Consider sending a full size CD in future that will work with all readers.

I wanted to sync a Palm IIIxe with a state of the art laptop running Windows 10 Pro. This worked like a charm.
