USB UART Win 8.1
Need to be pointed in the right direction for using the USB UART on Windows 8, which has strict digital signature enforcement.
Getting a prototype ready for a trade show I found that a Windows 8.1 tablet would not accept the unsigned setup .inf file so I came to the Cypress site and ran an installer that put drivers in Program Files (x86). It appears that the configuration of the part in Creator must be changed to be compatible with the .inf file. If this is true, not sure which strings to change. Also noticed there was no reference to usbser.sys in the file. Do I need to use some other driver?
Also, would like to get a digital signature for our product and modify the .inf file to use our corporate USB PID and VID. Should I open a case for this?
