I'm trying to get a java program to connect to a hid device on Fedora 30, but I get a 'errno 13' error when trying to connect
The software library creator and a user over on stack overflow have confirmed it's not a software library problem
My user has already been added to the wheel, dialout, and input groups with the same result
Can anyone suggest a way to get around this?
device path: /dev/input/by-id

1Are you running your program as root?
Errno 13is a permission denied error, so the problem seems really trivial. – Fanatique – 2019-06-07T08:51:37.550no, it's being launched from inside netbeans. If my user is in the right group shouldn't I be able to access the device anyway? – James Pollard – 2019-06-07T09:04:12.883
Please edit question with uid and gid of the process that's trying to connect, the path of the device it's trying to connect, and the permissions of that device. You can use
stracefor additional information, if that helps. – dirkt – 2019-06-08T18:16:47.290I'm not sure how to get the uid and gid of the process, it's launching from in my IDE Netbeans, it's not running long enough for me to run any additional commands – James Pollard – 2019-06-12T23:17:35.167
