Hello,
I had to buy new laptop with annoying Win8.1 and now my Iogear GUC232A (ATEN based). I downloaded the Win8 drivers from Iogear still no luck. Other adapter GoldX (Prolific based) is officially not compatible according to Microsoft. I am stuck with dead old laptop and Win8 incompatibility.
Any idea how to get around this?
Do the Parallax adapters work on Win8? Has anyone tried them?
Thanks.

Thanks.

Edit: Now the ATEN website says it is Win8 compatible, mayhaps the latest driver will get it going: http://www.aten.com/products/productItem.php?model_no=UC232A
Will order from Parallax today.
The BASIC Stamp has very strict timing requirements during programming so the Parallax Serial to USB Adapter is recommended.

And for you parallel port fans, also $4, PCI bus and Win 7/8 compatible. http://www.ebay.com/itm/IEEE-1284-25Pin-Parallel-Port-Printer-to-PCI-I-O-Controller-Card-Adapter-/301102005008?pt=US_Internal_Port_Expansion_Cards&hash=item461b13fb10

will work fine with built in windows drivers. I did have to let one netbook I have go look for a driver, but it did it by itself and now works fine.
There are several USB to Serial adapters that are only TTL that you might have trouble with those. If you go for the ones with the USB to DB-9, you should be fine.
I buy these: http://www.ebay.com/itm/1pcs-NEW-PL2303-USB-TTL-RS232-Convert-Serial-Cable-Connector-/141287376939?pt=US_Parallel_Serial_PS_2_Cables_Adapters&hash=item20e562482b to program my Propeller. As of yet, I have not been able to use my Propeller programmer on my Basic Stamp, Or, my Stamp programmer on my Propeller.
For what its worth...

The trouble might be inverted signals. One of the gurus in the PicAxe forum showed that the cheap CP2102 usb adapters worked only after adding two inverters : http://www.picaxeforum.co.uk/showthread.php?18715-problem-with-downloading-the-program-onto-the-picaxe&p=174475&viewfull=1#post174475 I copied his and it worked fine for Picaxe, which only needs tx & rx lines, not true for the BS2.
What are you programming? Stamp? Propeller? What? Sorry if you already said. Most Stamp interfaces I have seen are designed for RS-232 and my Propeller projects (and several others) all are TTL. THIS IS AN IMPORTANT DISTINCTION.
Does it look like the adapter you are using is loading drivers?
Are you using Win8?
Is your problem a driver problem or a problem with whatever you are trying to connect it to?
Does it show up in the Windows Device Manager as a valid com: port? If the adapter does not show up as a Com? port in the device manager, then it will never work.
ATEN adapters are pretty well supported. I use the 4-port ATEN adapters for my more sophisticated RS-232 devices. I don't think ATEN makes a TTL adapter. For that you need the $2 I pointed out in my first post.

Shows two different types, and the one marked "fake" is the one I have here (which doesn't work), with the big epoxy blob. Maybe I got two of the fakes. Can't find the other one, I may have tossed it.
I have an inexpensive Windows7 Netbook and I run dropbox between it and my main computer. All my software that I need to load into my device I can run on my main desktop system (fast computer and any operating system) then, when I want to load my board level devices, I use the Netbook. Because it is constantly in sync with my dropbox folder, there is no problem.
ATEN says that they have drivers for WIN8 on their website.
Sorry I can't be of more help.

Yes, but it bombs on install and says the earlier versions won't work. Fortunately, Parallax's own fine FTDI adapter works fine.
I ordered the blue one in your link to try, too. Thanks.
BTW, this particular blue cable installs as a Prolific chipset, but it looks like the "fake" version (epoxy blob instead of IC visible) detailed in the post #18.
