Hello, using an old CY4500 on a new PC, 2020-11-03:

• Download and install CY4500 software from website, dated 2020-10-09
• Plug in CY4500
• Error, drivers not installed
• Read quick start, it says to look for drivers in the install directory
• No drivers are in install directory
• No old versions of CY4500 software are available on the website

Any idea how to make this work?

Thanks

I found an old copy of the CY4500 software which installed the drivers corresponding to its version. The recent version of the CY4500 software was then able to update firmware and it works.

However it is great to know the driver is just WinUSB.

This is caused by Win7. Enter the URL below and follow the steps.

https://www.catalog.update.microsoft.com/Home.aspx

Search for "windows phone winusb" in the Microsoft Update Catalog.

Download "Windows Phone - Other hardware - WinUsb Device".

Extract the contents of the downloaded '.cab' file to a temporary folder.

In the Device Manager, select Update driver software > Browse my computer for driver software.

Navigate to the temporary folder with the downloaded driver and complete the installation.
