Hello, Hope someone can help with this issue: all usb ports stoppped on Flex 3-1480 running Windows 10 64-bit. Tried several attempts to re-install driver, regedit, delete drive, auto discover driver - all attempts fail. Also, tried restore point - did not fix.
In addition to usb ports stopped working - touch screen is not working either.
All drivers are supposed current (at least when i scan for changes; Windows 10 was updated after problem started (so that rules out drivers and operating system)
Microsoft Management Console - Event Viewer shows USB Root Hub (xHCI) problems - all during the times attempting to resolve.
However, around time of initial failure - The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001e (0xffffffffc0000094, 0xfffff802e80a9e8c, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: 2ea1e93b-3f55-4d1b-b11b-1cd80d6a944d..
Minutes before memory dump - The driver \Driver\USBHUB3 failed to load for the device USB\ROOT_HUB30\4&b338d6a&0&0. - (appears as a warning)
With the warning is an informational:
The description for Event ID 26 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.

Thanks for using the Lenovo forums.
Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.
(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal
If these steps do not work I would recommend, that you call your local Lenovo support line for a possible service. Below is the link to the phone list where you can find these numbers
Hope this helps, let us know how you get on.
