I'm using Ubuntu 20.04 on dual boot with Windows. My problem is, I cannot use USB tethering in Ubuntu but WiFi works fine. On the other hand, windows works well (both USB tethering and WiFi works well). There's one more thing. If I use any other mobile phone (Samsung) with USB tethering its works well in Ubuntu except one mobile (also Samsung) but that works in Windows.
I tried to update drivers with software setting additional drivers tab but it shows "No additional drivers available." When I use lsusb it shows:

Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
