## Questions & Answers

**Q: Have the cd drive include?**
A: I'm not positive what you are asking here but I will try and answer what I think you are asking. This is a USB to RS232 adapter. There is no drive to be included here. There is no software drivr needed for it to operate your Windows operating system should recognise it when you plug it in and load its driver. In other words it is totally plug and play. I have heard that some RS232 devices do not work with it but so far I have had good luck with everything I have connected it to. Hope that answered your question.

    Works great and durable
  

*by K***R on Reviewed in the United States on July 17, 2012*

I have used a couple different USB to RS-232 converters and I am quite pleased with this one.  It is compact, robust, and works well.  There are no status lights - not important for my use but maybe for others. I use a HP EliteBook 8440p running Windows XP.

    Corrupted computer windows 10
  

*by K***R on Reviewed in the United States on May 26, 2023*

Installed driver from the device itself and it told me to restart computer to get it to work. Now computer is corrupted and will not get off the blue screen. Without installing the driver on 2 other computers, it will not work. The older versions of windows never showed the driver to install and the newer version corrupts it. Worst purchase I ever bought. Had to get computer fix.

    It DOES work on Mac
  

*by T***S on Reviewed in the United States on March 24, 2011*

I saw a review that said that this does not work with Mac as advertised, but it does. I bought this for use with my Macbook Air primarily to use to for console connections on network devices. My Mac did not recognize the device until I installed the PL2303 driver. This can be found on the driver disc that comes with the product. But since I don't have a CD drive in my Macbook Air, I downloaded the driver from here: [...]. The PL2303 driver is also needed for use on Linux, but most popular Linux distributions already have it installed.I previously owned the USB-to-Serial adapter depicted in the picture above, and recently misplaced it. So I bought this product (DX-UBDB9) at a Best Buy. It is the same part number as the one mentioned on this page, but it was not the one in the picture above. I'm not sure if Dynex updated the product and kept the same part number or what. However, mine is Tan, not Grey. And my only trivial complaint is that the one I purchased has some kind of a transformer midway through the cable, where the one in the picture on this page didn't have one and was, therefore, slightly less bulky.
