USB 2 devices not working on USB 3.0 ports

[tranchec]

Hello,
I have a laptop (ASUS K555U, windows 10 64bits) equipped with two USB 3.0 ports and one USB 2.0 port. Everything was working fine until the USB 3.0 ports stopped seeing 2.0 devices (I tried several : a mouse, a soundcard, an iPhone, USB flash drive...). USB 3.0 devices (for example an external hdd) are working normally on every port.
For some USB 2.0 devices, the device manager shows an error code ("Windows has stopped this device because it has reported problems. (Code 43)"), for others, nothing appears.
All the devices I tried were working fine before this failure, and they still work on the USB 2.0 port.
I tried to update and reinstall the usb drivers, I tried older versions, udpating devices drivers, but nothing worked.
My USB drivers are (as shown in the device manager) :
- Intel® USB 3.0 eXtensible Host Controller Driver 1.0 (Microsoft)
- USB root hub (USB 3.0)
Right now, usb drivers are up to date, and so is Windows.
Thank you for your help !

I found someone with another Asus laptop with exact same problem, USB 3 works but USB 2 doesn't,

It shouldn't be a driver as USB 2 drivers built into Windows itself

To determine if this is a hardware or software problem, try booting into a Linux live CD and see if USB 2.0 devices work in the USB 3.0 ports. If they do work, the problem is in the drivers. If not, the problem is in the hardware.

Depends on stock drivers, bios, etc. Most manufacturers allow this capability, but some don't....

Thank you for your answers.

It would be surprinsing that backward compatibility was allowed (it worked two years until the failure), and then suddently removed ?

It is indeed the same problem than mine... I will try booting on Linux as advised.
