MacOS exception on Kernel Detach (FIXED) #88

Open dmingram66 opened 1 year ago

dmingram66 commented 1 year ago

MacOS introduced a security control with BigSur which prevents un trusted developers from detaching the Kernel USB driver. The attached patch file implement the fix.

Please note that I have introduced a new dependency, from packaging import version , to allow a simple version test:

            if not sys.platform.startswith('darwin'):
                try:
                    self.device.detach_kernel_driver(0)
                except usb.core.USBError as e:
                    raise BlinkStickException("Could not detach kernel driver: %s" % str(e))
            elif version.parse(os.uname().release)<version.parse('20.0.0'):
                try:
                    self.device.detach_kernel_driver(0)
                except usb.core.USBError as e:
                    raise BlinkStickException("Could not detach kernel driver: %s" % str(e))

The attached file contains the patch
