Original question:

EV2300: Unable to get the EV2300 usb driver working on windows 10

Will TI ever provide Signed Drivers for TI USB related devices running on MS Windows?

 As you may be aware, Microsoft is slowly tightening the noose regarding the use of unsigned drivers especially related to Windows 10. As Microsoft states, Starting with new installations of Windows 10, version 1607, the previously defined driver signing rules will be enforced by the Operating System, and Windows 10, version 1607 will not load any new kernel mode drivers which are not signed by the Dev Portal. Their rationale is that this is for security purposes.

We have been using an unsigned TI USB Boot loader driver (with driver signing disabled) to install and run the boot loader. on Win 7 & 10 PCs. We use it to facilitate loading Firmware on our TI based product in manufacturing. Recently, the Boot loader stopped working when a recent update of MS WIN 10  (Version 1803) was applied. Since our company policy now forces us to run on all WIN 10 PCs with the latest updates (for security purposes), reverting to a previous update (or running on Win 7 PCs) is not an acceptable option for us.

Is TI planning to supply signed drivers for their MS WIndows based  products in the near future to help alleviate this situation? It seems like more customers will start to run into this as they switch over to WIN 10, or apply the latest updates on their existing WIN 10 PCs.

Please advise ASAP,

Thanks,

    Hi Jim,

    I'm not familiar with this part but I see the website says "Note: EV2300 is not supported for 64-bit Windows (Windows 7 and newer). This product continues to be in production to support existing customers." I will try to re-assign to the appropriate organization handling this part for their comment.

    Brian,

    I mean't  this post as a general question related to TI USB drivers, and intended this to go to the USB forum. I didn't notice this was related to EV2300 which we don't use

    Thanks for the quick response,

    Jim

    Jim,

    I can't speak for other organizations within TI, but our product line does digitally sign the drivers for any Windows SW that we release.

    Brian,

    OK, so the driver we are using is related to the C55XX DSPs: (C55xx_USB_EP_64.sys) which is an unsigned driver. I originally posted the issue I described on that Forum over a month ago, but the response was to simply Disable Driving Signing. The problem with that is it makes our systems less secure, and also vulnerable to the next Microsoft update that trashes it out again.

    Anyway, as I mentioned I posed this as general question to see if there was TI policy regarding driver signing, but it sounds like it varies depending on the product line within TI. To me It seems like the real solution is to obtain a signed driver somehow , but not sure the best place in TI to forward this. Please let me know if you have additional thoughts.

    Thanks again for the quick response,

    Jim

    Hi Jim,

    Unfortunately, we do not have any company wide policy regarding signing so it's product line dependent. I can only suggest you request it for the particular parts you are concerned with and let them know disabling signature enforcement is not an option for you.
