(1 star) Not support for Windows 10

By: Dougbert78
Totally unacceptable that Startech doesn't have updated drivers for an OS that is now 5 years old and Microsoft is committed to solely supporting now that windows 7 is going defunct. Put out an updated driver for this already!

It's important to us that our customers have a positive experience with our products and we're sorry to hear that our ICUSB2321X is no longer working for you. This adapter is not supported in Windows 10 but you may be able to install the drivers if you disable driver signature enforcement in Windows. If this does not allow the drivers to install or if you're not able to disable this setting, we recommend looking at a different USB to Serial adapter such as our ICUSB2321F which uses an FTDI chipset and has Windows 10 support.

(1 star) Does not work with Windows 10

By: rs323sucks
Worked fine with Windows 7, but purchased a new PC with Windows 10 and found that I can no longer do my job as this adapter does not work with Windows 10. Seems like updating the drivers would not have been impossible, as every other piece of technology works.

We apologize for the difficulties you're experiencing with our ICUSB2321X. This adapter is not supported in Windows 10 however you may be able to install the drivers by disabling Driver Signature Enforcement. If this does not work, we recommend looking at a different adapter for Windows 10 compatibility, such as our ICUSB2321F.

Purchased by my company It will not work at all on Windows 10 the drivers are not recognised (unsigned) and will not load. Unusual for Startech to provide such a product without a platform use warning - ie not compatible with Windows 10
