Works with Windows 10 and Windows 8.1 11/12/2016 8:03:23 AM

Pros: Actually works with Windows 10 and 8.1. Many other adapters either would not work flat-out with the newer Windows versions, or would cause a bluescreen. This model - when installed with the manufacturers drivers - offers stable COM port access via USB. I use this extensively to program / manipulate routers, firewalls and switches.

Cons: As mentioned above - you need to make sure to use the manufacturers drivers. I've had Windows 10, post-anniversary update still bluescreen using this. It was my bad, just plugged it in and used it without checking - it decided to use the generic MS driver.

Great Device 12/6/2013 6:18:51 AM

Pros: Works Out of Blister Package on my work machine (Win7 Pro x64) my personal machines (Linux), a Win8 Tablet w/ USB OTG adatper and even had to plug it into a server (MS 2k8 R2 x64) because I did not want to stand in my server room when the temp is <60!

I love having the status LED. Very useful if you are attempting to troubleshoot a BAUD rate or other cause of a console not displaying while attempting access.

Cons: None

Overall Review: I use this more frequently than I care to acknowledge. There is still a wealth of devices that need this to access & configure.

I have used it on devices ranging from Cisco to Siemens.

Some times I wish laptops still had RS232/COM/Console ports! But then I remember how wide that 9 pin port was and how much I appreciate my thin machines.

Do NOT Buy!!!!!!!! 7/2/2013 7:46:49 AM

Pros: It works fine on most computers.

Cons: On my laptop, I'm running 64-bit Windows 7. I get BSOD often. I have read review from 2010 with this issue. I have talked with Tech Support, and they swear that it's not their problem, but they can't tell me what the problem is. They said that they were going to come out with new drivers to fix this issue years ago. Don't count on it. Terrible product. Terrible Tech Support. Worthless.

Avoid on Win7 64-bit 6/22/2012 8:09:59 AM

Pros: Don't have any because this device is essentially useless for my purposes.

Cons: Did not work properly on Windows 7 64-bit. I upgraded my drivers to the lastest version that IOgear has posted on their website. Still getting blue screens. Also, when using to console into equipment, the device output will occasionally freeze, and I have to restart the session.
