Activate driver extension failed "OSSystemExtensionErrorDomain Code=8"

Hi

I have downloaded the sample code from "https://github.com/knightsc/USBApp".

I'm trying to activate driver extension, but activationRequest always fail with "OSSystemExtensionErrorDomain Code=8" error.


------ error message------

sysex didFailWithError Error Domain=OSSystemExtensionErrorDomain Code=8

"Invalid code signature or missing entitlements" UserInfo={NSLocalizedDescription=Invalid code signature or missing entitlements}

--------------------------------


A related entilement request has been sent, but no response has been received.

So I edit "com.apple.developer.driverkit" value to "NO" on entitlement file for compile the code.

I've modifies code about driver extension identifier and device information for my device.


After compile the code, driver extension and USBApp codesign with Developer Application ID.

(If codesign is not done, when launching USBApp crash occurred with Signing problem.)


Also i did disable SIP.

What am I missing?

Any help in solving this problem would be greatly appreciated.
