LENOVO G40-70 Model: 20369 USB 2.0 Not Work.

Hi, i'm from Colombia, my Lenovo Laptop, just auto-update to latest version from Windows 10
After his reboot, only the 3.0 port is working, laptop have 3 USB ports (1 USB is 3.0 and other 2 are 2.0), and now, only the 3.0 port is working, other ports are giving energy (i put my phone for try, it's only charging, but don't read data or USB recognize), the USB 3.0 port read data, charge, etc etc..
I tried update again, downgrade, tools from Microsoft to solve, and NOTHING WORK.

Windows 10 updates can cause all kinds of issues. Usually the drivers are the first and worst impacted. Try looking for a new driver for the USB (regular not 2.0) ports and see if you can re-install with admin privileges.


I do not work for Lenovo, I only provide suggestions based on my personal willingness to help others. All advice and comments are based on my experience, and do not reflect Lenovo policy, terms or conditions.
