Laptop USBs not working correctly.
Hello there.
When I first bought the Lenovo V310-15IKB laptop, everything was working as intended, after some years problems with USBs started showing up. At first, the USB 2.0 port stopped recognizing USB 3.0 devices, then it stopped working completely. After some time, one of my USB 3.0 ports stopped working with USB 2.0 devices, and then the same problem appeared in the other USB 3.0 port.
Now I have no way to use any USB 2.0 device. Also, I cannot transfer files from my phone (which I connect using a USB 3.0 to USB type C cable. And I was able to do this previously.)
I have not made any USB related changes to the system before observing the problems.
I have tried using different OSs (Linux and Windows) and also installing and reinstalling every driver provided in Lenovo website. I also tried upgrading the firmware and disabling USB suspension in Linux. Nothing worked.
I think (I am really not a expert in this kind of matters) that it is good to mention that my battery is old and not healthy.
I have no idea what the actual cause of the problem is, so you are so kind if you help me. Thank you.

Hi @aerfanr ,
Do the USB ports supply power to the USB devices that are connected to them?
Plug in a mobile phone or a USB mouse with a laser lens and check if they give an indication of power being supplied by the laptop i.e. phone starts to charge or mouse lights up. The device may not “connect” as there may be a problem with the USB controller or USB data link but most USB devices need power from the laptop just so that they can "talk" to the laptop. Without it nothing happens.

Thanks for your comment @jayeff
Yes my phone starts charging when I connect it and when I connect a mouse, its light starts blinking. Also I have a USB 2.0 flash drive with a LED on it, the LED blinks once when I connect it and I cannot use the drive.
