W10 doesn't detect external drives when plugging, but does on startup

Hi there!
Thanks in advance for the help.

Well, the problem is as simple to explain as the title of the thread sujests: when I plug my hdd drive on a usb, Windows doesn't even detect it (to the best of my knowledge it doesn't even show up on Device manager, even after hitting "Scan for hardware changes"). BUT when I shutdown or restart with the HDD plugged in, it does show up on This PC and is fully functional.

The problem is exactly the same both for 2.0 and for 3.0 USBs.

I think I have the latest drivers for everything, installed directly from my mobo manufacturer's page, also through the App Center (my manufacturer is Gigabyte) and through "AMD Software" application (I have a Ryzen 5 1600).
Even so I'd be more than happy to provide you with the version of any driver you ask. Just want to get this sorted out as soon as possible.

The only further information I can provide is that it worked at some point, but I don't know when exactly stopped working, because I did a lot of stuff in between.

Oh, I also used DriverEasy to update some drivers.

Well, hope I provided the information you need to start helping me and thanks in advance for your help.

PS: I've just now thought of letting you know that I have Ultra Fast Boot enabled, just in case, even though I don't know if that has anything to do with it.

Try opening a command prompt (Admin) press Enter after each command.

diskpart
automount enable
exit

See if that fixes it.

Nope, no luck with that unfortunately.

Sorry for doubleposting but I have new information that I assume will come in handy for you guys, and it's weird as **** too.

I have just plugged a pen and W10 automatically mounted it no problem (I didn't have one in hand previously to try), then I unplugged it to test the hdd drive for magics sake but nothing happened, and now I plug my flash drive and W10 doesn't recognize it. Wtf xD

It's as if somehow my hdd drive messes with the USBs, I don't understand xD

EDIT: After restarting I can plug in my flash drive and it work perfectly after removing and plugging it repetedly. It seems it's the hdd that does something weird to the usb ports or something, I wouldn't know.
Could it be a power thing (voltage)? Though in that case I guess it shouldn't work even if it's plugged in when starting the computer.

So, I'm thirdposting xD

My external HDD has this format: HDD <- plug in cable -> PC (I mean, you plug it both ways).
What I was doing all the time: cable already plugged in HDD, and plug it into the pc.
What I did this time: cable already plugged in HDD, plug it in pc, unplug from HDD side, plug again the HDD.
Now it works ALL THE TIME.

I can't even xDDDDDD
Well, I'll mark this as solved though I still have no idea what was causing this random ass bug xD

Thanks for letting us know how you solved it.
