    Hello guys, I'm looking for some help...

    I was charging my Smartwatch with a not original and not capable charger ( I was experimenting with something ) from my laptop's 2 USB ports. And after that I got my 2 ports not working anymore ... they charge but don't read any USB device.

    I tried everything to fix this problem... but unfortunately, nothing fix my problem.

    Anyone had the same problem?

    MIght be a blown USB controller, sometimes caused by a bad device or bad cable (or an actually broken port).

    Unplug your computer (or pull battery and unplug, if laptop) and press and hold the power button for a few seconds. Plug it all back in and fire it up.

    This resets the CMOS, but also clears some some of the onboard device configs, which may fix your USB if there's some corrupt config or a blown soft fuse.

    In any case, don't use that cable / charger with a computer any longer.

    Thanks for the replay,

    I previously tried to unplug my battery connector waited for a couple of minutes and then plug it again without pressing the power button while the battery cable was disconnected. And did not work for me.

    So as I understand I made a mistake not pressing the power button while the battery was disconnected?

    Thanks.
