USB 2.0 to RS232

I needed this to access a micro controller board, and although the ports show up they are not emulating a serial. if anyone has suggestions

Fine if you are using a 10-15 year old computer but not valid for a modern machine as it does not have drivers for anything released in this millenium.

This adapter cable does not work with Windows XP, Vista or 7. I have spent 8 hours trying to make it work, installing different drivers, etc.
I would like to return the adapter, but return shipping costs more than the adapter did. I have been cheated out of my money and 8 hours of time.
I am surprised that Amazon allows vendors to sell faulty merchandise. I guess the almighty dollar speaks louder than these reviews. It would be nice to be credited for our troubles.

I bought this to use with some of my hardware devices that have serial ports that allowed me to use a backdoor to access the firmware in the device (ex: Netgear WG302). Windows 7 recognized the device and, with the aid of the included CD, installed and recognized the device as a USB-Serial cable. That's about as far as I got. I usually use hyper terminal in Windows to access the device via serial ports. But, even though I programmed the drivers to use specific ports in case there were port conflicts, I couldn't get any results. My advice to anyone wanting a more high-tech way to perform a firmware upgrade to their devices: Keep hanging onto your old computers. I have a laptop that I do firmware upgrades with. That way, even though I won't use it for anything else, it's small enough not to be an inconvenience.

Installing this device to Windows Vista caused the dreaded blue screen of death every time I plugged it into a USB port. The drivers loaded to the computer without any errors, but as soon I plugged in the cord and the USB manager "sensed" the device, it would trigger an IRQ conflict resulting in a stack dump.

I ended up tossing it in the trash.
