USB Tethering

• Android USB tethering may be limited to ~150 Mbit due to USB networking emulation.
• iOS 13+ USB tethering is not officially supported due to practicality issues:
  • You need to tap "Trust" on every reconnection/hiccup with usbmuxd, unlike iTunes.
  • If the cellular signal is weak, tethering will automatically disconnect, requiring USB physical reconnection to continue tethering.
  • Partial workarounds.
