Can not install any USB flash or hard disk

Hello everyone!

I could not install any USB devices yesterday. My colleague gave me a Kingston flash disk and asked me to copy some files for him. but when I plugged it into my laptop, OS discovered a new hardware was plugged, but it couldn’t install driver for it. After I uninstall CIS, it worked normally.

I got some messages about CIS or CFP in earlier version may cause this kind of issue from Google. But I’ve install the latest version of CIS. The issue remains now. Who can help me?

By the way. I can’t add any file to ‘my own safe files’.

Thanks!

May be you changed settings when you configured CIS?
