This dongle is recognized out of the box under Centos 7. You get a usbX device. You need to run a dhcp client on the device or there is the option to set an address 192.168.2.[2-254] cause the dongle WUI has 192.168.2.1. There is a hidden menu to access and disable the dhcpd server on the dongle so that you won't need to use dhcp client hooks to avoid your rooting table and dns settings getting changed.
