This is your problem. Your provider has a limitation which prevents it from working in certain use cases. The obvious fix is to correct the permissions on your device node so it can be opened by the unprivileged process. There are other possibilities (e.g. descriptor passing), but generally they introduce complexity for little or no additional security. -- Michael Wojcik
