Thank you sir! Can’t believe what trouble I had finding this. Appreciate your help.
You are welcome 🙂 I had trouble finding the drivers which is the reason I posted!
Thank you for this post! Lost the CD that it came with and worried I wouldn’t be able to use this adaptor again.
Just wanted to say Thank you for posting this and the drivers….made my life so much easier for a moment in time….
Thanks for posting. The driver download fixed my problem.
Thanks you…
Thank you my good Sir! I can finally connect to my megasquirt and make the useless gigaware disc into a clay pigeon.
You have no idea how much time and frustration you just saved me! Thank you so much for posting this! Works like a charm, and my business is back up and running smoothly!
Nice… You had exactly what I needed!
Amazing! THank you so much
Thanks, Works great
Hi.. I try to click the download exe format but it sent me to microsoft. Do I have to login so I can download the file. Or there is a website that i can go and just click the download. Thanks….
The files are hosted in Microsoft Onedrive. You simply right click the file and it will give you the option to save it to your computer.
Can you post the driver without an exe file?
It is available in zip format, unfortunately in that zip file is an executable. Feel free to check it with AV before running.
You need to let people know that this is a DriverMax8 installer it isn’t the actual driver. DriverMax is one of those programs that installs, scans your PC then attempts to download and install drivers from it’s own mothership server. In this case – as of the date I posted this – this works for this dongle. But there is no guarantee it will continue to work in the future as DriverMax may decide to pull the driver.
Once the driver for the USB dongle is installed, it is possible to uninstall DriverMax8 from Add Remove Programs. Although you will need to manually delete c:\program files(x86)\Innovative Solutions since the DriverMax uninstaller is sloppy.
The actual driver is Svk2pl64.sys it is available from the Microsoft Update Catalog here:
http://catalog.update.microsoft.com/v7/site/ScopedViewRedirect.aspx?updateid=bad0b774-dce2-483e-a17e-1a7dc733e7d3 but you will need to use IE9 for this link or Chrome. It will come down as a cab file, extract from there then right-click the unknown device in device manager and install it. It is a Vista driver with both 32bit and 64 bit versions and should install in win 7/8/10. The actual chip is a Prolific chip with a modded USB ID you may be able to force-install an older Prolific driver on it.
I wrote a big article on these dongles here:

Enjoy!
I’m a tech and putty into a lot of equipment. New laptop, windows 10 but the driver for the com port (Gigaware) wasn’t recognized….code 10. Been looking for the driver….for ever. Noone knew how to help. Downloaded Cisco’s driver, didn’t work. Changed the compatibility on my laptop to Windows 7. I’m testing this out on Monday. If it works…..dude, you ROCK!!!
Just tried and it says unable to download driver
yes, it’s good. I downloaded it. and it works
Thanks so much! The right solution at the right time! Might want to let people know that in order to complete the process they need to be connected to a working network.
Excellent, confirm it works. Thanks a bunch!
You sir, are a gentleman and a saint. Confirmed in Windows 10. Thanks!
Hey Thank You a ton .. worked like a charm !!
Confirmed in Win 10. Thank you so much!
Thanks for this post, I can use my Gigaware Canle in Win 10!
Thank you so much! I switched computers and needed this. Thank you for making it available for everyone that need it.
I have literally been looking for this driver for years…YEARS. I bought one of these cables back in 2014 and have NEVER been able to use it…until now. Thanks.

Keep this site going, because you just saved me from a big headache! Thank you, sir!
Thank you so much. This device cannot start. (Code 10), Fixed. now Gigaware cable working on windows 10.
