Hello, I have a weird issue with the firewall running (Centos 7.9) wit an application. The application pulls data from an Ad-converter card, via USB, and sends the data to a db server using curl. (via a wireless device that is plugged into USB. When the firewall is running I get all kinds of weird errors (in that application), usb-port related BUT when the firewall is not running, it works just fine. (I wonder if it is a memory issue?) any ideas here? thanks, Ron
