Your phone charges, but the computer doesn't see it? USB Drivers tells you why – live, on the phone itself – and walks you through the fix. Live USB diagnosis • Detects a charge-only cable: the phone gets power from the USB port, but no data connection comes up • Tells a wall charger from a computer port • Notices when the computer sees the phone but hasn't finished the setup (usually a missing driver) • Shows the active USB mode: file transfer (MTP), photos (PTP), USB debugging (ADB), tethering, MIDI, webcam • Reminds you to unlock the screen when files are hidden • Shows the state of developer options, USB debugging and wireless debugging Step-by-step wizard Pick what you want to do – copy files, use ADB or connect without a cable – and follow the steps. Steps turn green by themselves as soon as the phone confirms them. Instructions match your phone's brand (Samsung, Xiaomi, Pixel, OnePlus, Motorola, Huawei and more), including where to find the build number and extra switches some brands require.
