    USB drives cannot be detected, unless the storage part receives enough power.

    USB flash key 5V @ 100mA to 200mA

    SSD drive on USB3 adapter 5V @ 500mA to 700mA

    Toshiba laptop drive on USB 5V @ 1000mA (spinup current) requires a two-headed cable

    The devices seldom have documentation which mentions
    the amount of power required.

    A USB2 dual-stack can be fitted with a 1.1A Polyfuse (on the motherboard).
    But this is not usually enough for the laptop drive example.

    It is rare for USB adapters to have barrel power jack inputs
    for a wall adapter. Normally, larger enclosures come with
    proper power.
