Windows 10: USB devices don't work on system start

It's kinda strange. Some of my devices (my external HDD and my keyboard) work fine after I completely power down my system and start it up, some don't. My mouse "works" but is screwed "LED doesn't work, touching it causes cursor to fly around with ridiculous speeds". My USB HUB that is built-in my monitor doesn't work at all.

It works when I restart the PC without powering it down (by turning off the PDU). It gets screwed once the MOBO loses power completely. Both the mouse and USB hub in my monitor work perfectly after unplugging and plugging them back in.

Of course I tried the obvious already: moving the devices to another ports, using only some of them and unplugging the rest, updating drivers, disabling selective suspending, disabling the power saving options on USB hub in device manager, playing around with BIOS USB settings. NOTHING works.

Keep in mind that if I unplug the device after win10 starts, and plug it back in, it works perfectly.

It began after I changed my MOBO so I'm sure that MOBO is at fault, but the question is: is it hardware related (and thus I have to live with it, or don't turn down the PDU for the night maybe) or software/driver related and thus fixable.

The devices worked perfectly on previous MOBO so any device malfunction is impossible at this point.

USB 2.0 devices don't work

Its not the cords or the ports...because my USB 3.0 devices work on all the ports..but it doesn't recognize USB 2.0 on any ports..like my iPhone or a normal usb drive..will not work ..I also replaced the battery..because I thought maybe they were not getting
enough energy..I also turned off the suspension of the ports to save power in power management..it still powers thing just does not recognize usb 2.0 devices

 

USB 2.0 devices don't work

Hi,

When the USB port is not recognizing any USB devices, then it could be that you're using a faulty cord. Another factors are due to incompatible USB device, or a corrupted USB 2.0 port. Now, to determine if this is indeed the case, we suggest that you download
and run the Windows USB Troubleshooter from this article:
Automatically diagnose and fix Windows USB problems.

You may also try using another USB 2.0 cord and check if it's still the same.

Let us know the outcome.
