  • Submit a PR or discussion post to add fully tested hardware (optionally: for 2 months or more) followed by your username.
  • Tests are not recommendations, community reports are not always accurate, use the list for reference only.
  • Android USB tethering may be limited to ~150 Mbit due to networking emulation.
  • iOS 13+ USB tethering is not officially supported since it is impractical:
    • Need to tap "Trust" on every reconnection/hiccup up with usbmuxd unlike iTunes
    • If cellular signal is weak, tethering will automatically disconnect requiring USB physical reconnection to continue tethering.
    • Partial workarounds
