So, you can use the same Mac OSX driver they distribute which happens to support Lion. Prolific Technology’s PL2303 device is essentially the same product as the ATEN UC232A adapter. The question is can I actually get a driver that supports Lion in 64 bit mode for this adapter. I find a post that mentions that because this particular adapter was only supported with the original 32 bit drivers that Lion essentially disabled support because of the default 64 bit subsystem. So, I did some more searching, looking for people having problems getting this working with Mac OSX Lion. However, I did discover a number of posts referring to a company by the name of Prolific having a product that was 100% compatible if not identical to this particular ATEN device. I find out that ATEN has basically disappeared. So I do a quick Google search looking for any info on this product. So, now I know that it is made by ATEN International Co.

It took me a few weeks of trial and error and searching around to finally resolve the issue.

So, I was determined to figure out how to get it to work, as I no longer have any physical machines running Windows or with serial ports. I had a VM running Windows XP and I was not able to get it to work properly in that environment either. However, I had tried using it on my Macbook running OSX Lion and noticed that it did not show up in my device list in ZTerm. I have never had an issue using it with Windows machines. I’ve had this USB Serial adapter for many years which I use to attach to network equipment consoles for initial configuration and setup.
