    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….

  14. JimHe says:

    Can you post the driver without an exe file?

  15. 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: 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:

    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!!!
