StarTech.com 1 ft. USB to RS232 Serial DB9 Adapter Cable with COM Port Retention - Up to 920 kpbs USB A to DB9 Serial Adapter , TAA (ICUSB232PRO)

We use this with multiple laptops that download from GPS units and need to be reliable and simple. Telling people how to use Device Manager to find where the USB-Serial adapter went doesn't cut it. I can now configure the machines once and know it'll work every time. It installed perfectly on Windows XP, Windows 7 32-bit and Windows 7 64-bit. The fact that it arrives packed in an anti-static bag inside a cardboard box makes it clear it's not the typical cheap blister pack unit.

Be sure to check your COMPUTER and the signature pad you are ordering to make sure it's the correct one. Once we got the correct signature pad, this works perfectly. Easy to hook up...just find a USB port on your computer!

This works as expected

I love this product - makes life so much easier than dealing with a serial cable. Drivers are easy to install and adapter works reliably every time. Also very happy with ship time from Vendor.

With my new motherboard I no longer had any com ports and only USB ports. Bought the ICUSB232Pro from [...] and this USB to RS232 Serial Adapter Cable did the trick and ended all my problems. Works great in both Windows 7 Home Premium and Professional in 32 and 64 bit. Comes with drivers or just go to their web site and download their latest.

Although the printed manual does not specify, there is a driver for Vista. Didn't see any for W7. But, the Vista install went fast and perfectly. When I connected the cable to a usb port, it turned up as COM3. This product is perfect for my high-end laptop because it does not have a DB9 serial port. But, my hobbies and my job require that I be able to connect to a serial device using DB9 connectors. Double-click my heels!

EDITED: After a lot of investigation, I discovered that this device IS supported directly in the Linux OS and no driver installation is needed, but it is NOT intuitive to figure out how to use it for the average user. I wrote to StarTech with decent user information and asked them to post better instructions on their website, but they never did. The unit works fine, but I only raise my rating to a 3 due to lack of user information. To install this device all you need to do is to plug the adapter into the USB port and then do a "dmesg" command and look at the last few lines of the output to see the install results. WAS: Linux support (sic) consists of a Makefile and driver source code specific to an ANCIENT (March 2004) Linux kernel (2.4) for Red Hat Linux versions 7.3, 8, and 9. These are absolutely obsolete. It may run on Windows, but any mention of Linux needs to be either removed or severely qualified.

I would recommend most star tech products as I am a plc tech and use these in the field on a daily basis. Easy to install software for and never had any issues with the port dropping out. Also for how light weight it is, it has lasted a very long time from abuse in the industrial field compared to my C2G

Buen Articulo... tiempo de entrega muy largo para algo muy pequeño...

Excellent, actually worked as a USB to com adaptor for an application on an old CNC router, Not all adaptors do work!!

E' l'unico adattatore usb-seriale rs232 che funziona sempre e non da alcun problema. Provato con switch HP e altri apparati.

nachdem ich schon 2 andere bestellt hatte funktioniert dieser endlich wie gewünscht auch unter WIN11. dazu noch der extra schnelle Versand, macht rundum zufrieden

仕事でいまだにRS-232な環境があるため、ノートパソコンにUSBシリアル変換をつなげて 使用してきました。この製品はFTDIのチップ(おそらくFT232R)が使用されており、 さらにあらかじめシリアルナンバが書き込まれているため、違うUSBポートに差しても COMポートが無駄に増殖することはなく同じCOMポート番号で使用できるので快適に使用できます。 また、ボーレートに関しても看板に偽りなく921600bpsでも波形がなまらずきっちり 出ます。仕事で安心して使える逸品です！
