PSoC 5, 3 & 1 MCU

Hello everybody,

I have a testproject with a composite USB function.

It uses 2 HID Interfaces, 1 keyboard and 1 volume control.

Also It has an association descriptor, which explains the default USB UART CDC descriptors.

See the screenshot for more information.

If I want to use the UART functionality, I need to manual search and add the custom driver.

With Windows 8 and up it is even more difficult because the driver is not signed.

I have to edit some settings and restart multiple times.

Could I use generic signed drivers that do exactly the same?

Can you please check this KBA

The Creator generated .inf and also this .inf will point to the Microsoft serial driver which is signed. Additionally you can use Microsoft certified driver from Cypress. These drivers will be installed if you have installed the Cypress Serial SDK

Link: http://www.cypress.com/documentation/software-and-drivers/usb-serial-software-development-kit need to bind the device to the driver in the installation folder in this case.

Using the CyWinCDC.inf file from the example worked. Thanks for your quick reply.
