If you need to run a Windows 11 serial device(s) with a limited number of serial ports and not many options, it can be frustrating. The Gearmo 2 Port Professional USB 2.0 to Serial Converter FT2232D Chip with Power LED is a great solution. This RS232 2-port cable utilizes a high performance FTDI Chip that easily adds 2 standard serial ports to your desktop, laptop or other mobile device and fully supports Windows 11.
The converter’s serial outputs are automatically configured as additional COM ports. The USB 2.0 to Serial dual RS232 port converter cable is compatible with most GPS and PDA devices such as Garmin, Magellan, or Palm and peripherals in your office such as modems, printers, scanners, and digital cameras.
This serial converter cable has built-in protection against static electricity and surges up to 15KV giving you reliable data transfers and protects the converter and your equipment from damage due to over voltages.
- 5ft. USB 2.0 to Dual Serial Adapter converter cable
- Driver Disk (downloadable)
- Manual (downloadable)
USB Plug and Play allows easy installation and requires no IRQ, DMA, or I/O port resources which means more devices can be attached to your system without the hassles of device and resource conflicts. The 2 Port USB 2.0 to Serial RS-232 converter is suitable for general office, commercial and industrial use.
With a FTDI and SIPEX CHIP Powered by USB, the device does not require a power outlet. Once connected, the adapter retains its assigned serial COM port values, allowing the same values to automatically be re-assigned to the ports provided by the adapter in the event that it is disconnected, then re-connected to the host computer.

Gearmo 2 Port USB to Serial Professional Adapter works perfecrly.
Bought to replace two port serial PCE card. I had problems getting Windows XP under VMWaare under Windos to recognize card serial ports for an old Singer Monogramming sewing machine. Gearmo 2 Port USB to Serial Professional Adapter works perfectly. Mission accomplished!

Works with windows 10 and server 2012
I needed these for work as I have a pile of USB to serial adapters that do not work for whatever reason probably drivers. This works. I did have to use the supplied drivers on CD to 2012 servers but this is a improvement from the others I have bought. Recommended.
After years of struggling with buggy drivers and erratic configurations of these devices, especially ones based on the Prolific Tech chip set (as most of the inexpensive USB<–<serial cables are) this one "just works"! This one worked the very first time on WinXP, Win7-32, and on Win7-64. Even bigger surprise was that on Win7-64 (which is notoriously fussy about demanding officially-Microsoft-blessed "signed drivers") the device just "automagically" started working about 20 seconds after I plugged it in. Apparently, the FTDI chip (that this device is based on) is a known device in Win7's library of devices — I didn't even have to use the provided install CD or download a driver.
I use the device to connect legacy serial-interface GPS hardware and two-way radio modems to a laptop in my car. This is a notoriously noisy electrical environment, with all the electrical/electronic devices, alternator hash, etc. This device has been absolutely rock solid with none of the hiccups, random disconnects, etc I've had with other such cables.
Getting two serial ports for the cost of one USB port is a bonus, especially on netbooks with their limited supply of USB ports.

I work on tech and it requires a console connection to do the basic setup/troubleshooting. This sucker did a fantastic job and allows me to connect to multiple systems at the same time. The console ports are clearly marked, so their is no confusion about which cable is which port. It doesn’t slow down the response, either. I have seen some cables that split the connectivity so that you get 10-20 lines from one cable, then 10-20 lines from the other.
So, long and the short is that it works and does it easily. I mainly use a Mac, so I can provide OSX approval and confirmation of working. If you really press, I could provide iTerm2 settings that I use to capture my console logs and tell it to grab the ports for serial.
This same cable is now the standard cable to be purchased if anyone asks me. So, I would say go for it, if you need a dual-serial connection. It’s good and it works.

Finally! A usbrs232 adapter that actually works with no hassle!!
Just downloaded and installed the driver on my OSX 10.8.2 laptop and it all worked.
Same no hassle on my Win7-64 laptop.
Thank you FTDI!!!
Recently lost a day of work with adapters based on the Prolific chipset and drivers.

I bought four of these to use in an automated testing setup. The USB to serial adpaters that I had used previously would not load drivers correctly when used with certain computers. These adapters work perfectly with windows 7 and retain their com port assignment. These adapters do precisely what they claim to do, I highly reccomend them.

What can I say, it’s a USB to dual serial port adapter, and it works with Windows 7. Another cool thing is that it reflects the same port to the OS no matter what USB port you plug it into. You choose COM4 and COM5 for the serial ports, it’s ALWAYS COM4 and COM5, a good thing.
Well built, feels like it won’t break soon, and also has long wires so you probably won’t even need extensions if you’re working within a normal distance of your devices.
