Ideapad 300 15ISK USB 2.0 ports not working

Hi people,


i have an Ideapad 300-15ISK running Win10 Home and i have the following problem:


- the two USB2.0 ports stopped working. The controllers of these ports are not shown on the system manager. I've tried to reinstall them but it didn´t work. I´ve also tried to unistall all the USB controllers and reinstall but only the USB3.0 port is detected and works. I think the USB2.0 are not damaged cause they do provide power to charge the cellphone. It must be a driver problem. Any hint on how to fix this?


Thanks in advance,

Hi  Boardwalk,

Please try re-installing the Chipset driver for the system. Update both of them under chipset. 

Hope this helps.
