My Sophos SG-115 rev2 firewall cannot detect Huawei E3276s-920 4G LTE USB modem

Good day from Singapore,

My Sophos SG-115 rev 2 firewall cannot detect Huawei E3276s-920 4G LTE USB modem. UTM version is 9.703-3.

Do I need to upgrade the UTM version to get it working? Or perhaps Huawei E3276s-920 4G LTE USB modem is NOT supported at all? I would like to get Huawei E3276s-920 4G LTE USB modem working on my Sophos SG-115 rev 2 firewall.

Background and more troubleshooting details are here:

I am looking forward to your reply.

Thank you very much.
