    I have a security token for online banking (Bank of China) that fits in 3.5mm headphone jack. It gets power (through this port, not additional power source), the screen powers on but doesn't get detected. No ding noise from Windows 10 like a USB device would.

    I bought a 3.5mm to USB-C adapter but annoyingly my version of laptop doesn't have it (Lenovo T470p) whereas others in the range do..

    I swear it used to work but it's been a while since I last used it. I'm wondering if any Windows updates along the way have messed with something, or perhaps the Dolby audio software. I ended all the Dolby stuff from Task Manager but no change.

    Any ideas how I can troubleshoot this? Nothing comes up in Device Manager when I plug/unplug.

    Short of buying a few random 3.5mm to USB adapters online and trying my luck, any ideas I can try in the meantime?

    For shits and giggles I plugged it into my Samsung Galaxy but again, powered up and that's it. Phone didn't seem to notice.

    Does it purely get power from the port? Or does it somehow get some other signal Eg Audio, if it's the former then perhaps if you plugged it into another device Eg. just a regular MP3 player or phone and see what shows up?

    So, it’s meant to be detected? Like headphones connected? Or just take power?

    How does it work as a token?

    The audio jack is providing barely anything:


    Have you tried turning up the volume?
