Re: USB ports not working Lenovo y50-70

Hi Focus,


Welcome to the Lenovo community!

This controller enables USB over wireless as part of the Intel (WiDi) Wireless Display function. The yellow bank (or warning) just started occurring in early 2013. 


The wireless display portion of the WiDi driver would still continue to work even with the yellow bang.

Lenovo Support Site has the Intel WiDi driver   which addressed the yellow exclamation mark issue. 


Let us know how you get on.
