CC2540 "The third-party INF does not contain digital signature information" Windows 8

Other Parts Discussed in Thread: CC2540

Trying to install the CC2540 SDK but the usb CDC serial port won't install due to the missing signature.

Did not succeed trying to disable the Windows 8 signature control.

Any chance to have an update of the CDC serial port?

    I realize that this is an old post...but I am having this problem.

     

    So far I have been using a Windows 7 PC with btool for debugging my ble profile development. This worked fine for me because I used he Windows 7 PC to debug and used a Windows 8 PC for development (I have IAR 8.11 and SmartRF installed there).

    I want to start using my Windows 8 PC for debugging and I find that I an unable to install the driver (for the CC2540 USB Dongle) in Windows 8.

     

    Any pointers to a signed driver?

    I tried both methods of disabling the Windows 8 signature requirement at https://freevps.us/thread-6845.html

    Although both methods proceeded smoothly, when I tried to install the TI dongle, I still received the message about it not having a valid INF signature.  I know that the Windows 8 procedures happened correctly because now I have that "Test Mode" watermark on my Windows 8 screen.

    This would seem like a serious problem since new Windows machines come with WIndows 8.  I notice there has not been a response from TI.  Can't we get some drivers that are signed correctly for Windows 8.

    I agree that TI should be signing drivers now since that has been a 'requirement' since Vista was released.

     

    I just purchased the ez430 Chronos watch and the driver INF, modified April 10, 2013, isn't signed, so I can't use it without jumping through unnecessary hoops.
