Seems like a very silly decision or oversight by the manufacturer. See the attached photo to understand the problem, you've got a male fastener on both sides of the connection.
I can also leave these plugged in and the laptop running overnight. Had other individual ones that burned out leaving them running overnight.
Finally, since it uses the FTDI chipset, Mac drivers are readily available work flawlessly and the ports show up with names that actually make sense.
One tip: On my Mac, I installed 2 copies of Zterm and left 1 named 'Zterm' and the other 'Zterm 2'. This allows me to have two console sessions operating simultaneously. No problems.
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.
I heard that FTDI had great support. I really wanted a four port device, with female receptacles. This two-port cabled device was as close as I could get. So I do have a bit more of a cable mess than with Keyspan 49, the BSOD is gone.
The software is intuitive and integrated into Win7. I have two of these devices (4 ports total). They have serial numbers built in. So, when I move them around to different USB ports, they always come up with the same COM number. Not all drivers do this. Some report a different com port when plugged into a different USB port. It is much nicer to be able to label each of the connectors as COMxx instead of having to go to device manager each time I power up.
I am using 115,200 bps, but plan to move to faster speeds as I qualify my embedded device.
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.
