Hi,
If the above suggestion doesn't solve your problem, please try the following:
1. If this is an ASUS system, uninstall AiCharger+ and if it is installed
a. Please report back to the forum what the version number is
b. Reply to this thread and let us know the version number
2. Check your USB controllers in Device Manager
a. Is there an error code? If so what is it?
b. it the Microsoft driver? If not what is it?
c. try to update the USB drivers in Device Manager
3. If those don’t work file Windows Feedback bug using repro mode with the feedback app as described here (note, repro mode is only available to those who are part of the insiders program):
http://blogs.msdn.com/b/usbcoreblog/archive/2015/08/17/filing-usb-feedback-with-repro-mode-in-windows-10.aspx
and include the following in the bug:
a. If the issue is happening all the time or only after certain events (such as waking from sleep)
b. If all your ports are not working, or if this is only happening on a specific port
If these steps don't fix your problem, please file the Windows Feedback. This will give us more info as to what is going on.
Thanks!
Kristin
