In 2009 I upgraded to a computer system using Windows 7 Pro and of course no RS-232 serial port. I have been using an RSI-CED Millenium chronograph for years and have acquired an extensive amount of data over the years with this system. The manufacturer of the chronograph recommended Serialio.com as a source for a USB to RS-232 serial adapter. I ordered one in January of 2010 and promptly received it. When I tried it, and the enclosed software, I could not get it to work on my system running Windows 7. Like a stubborn fool I would try different things and downloads with no success. I didn't bother to contact customer support until November 2010 - I figured for a $19.95 cable I would just be wasting more time. What a pleasant surprise!! I received a reply and a possible fix in a matter of HOURS!!! Due to my inexperience with Windows 7 I could not get the download, suggested by Serialio, to extract. I sent an email back explaining my problem and in less than an hour I had a reply and a solution to my problem!!! Any company that has customer support like this for an item as small as a $20. cable, and to still support it after 10 months of my procrastination, has to be one of the BEST companies out there!! Thanks again to Jordan for his quick, professional responses and to the SerialiO company for their excellent products. I would not hesitate to try any of their products in the future.

USB Hub Notes
The adapter works with virtually all powered USB hubs. With OS X use is painless, just plug-and-use. Windows versions prior to XP are notorious for quirky issues with devices on USB hubs, be sure to choose a good USB hub if you plan to use Windows prior to XP - this goes for all USB devices over hubs on older Windows, not just this USB to RS-232 adapter.
