Help... USB not working for mouse/keyboard
Images of current issue:
From device manager-
I uninstalled each controller and tried a re-install and received the following error-
USB mouse lights up but I cannot get it to work. Currently using PS2 mouse and keyboard. I have tried several times to update drivers but to no avail.
When I look at the properties of the driver I see the following-
It seems to be a digital signature issue. I believe it is the usbohci.sys driver as it does not appear to have a digital signature. I confirmed on an ideticall PC in our office that this is normally a digitally signed driver-
How can I resolve this issue??? Have been working on it for hours but have hit a brick wall. Any help would be very much appreciated.

this fix is from the link below and is the first response for code 52.
"Boot into Advanced Boot Options and disable driver signing checking.
The Advanced Boot Options screen lets you start Windows in advanced troubleshooting modes. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.
Disabling driver signature enforcement has helped a lot of users in fixing the issue.
You may also delete the USB "Upper Filter" & "Lower Filter" Entry and check if that helps.

A "Device Manager" window will open, click "Show Hidden Devices" in the View menu.
You can now uninstall any invalid/disconnected devices.
Once you have finished uninstalling devices restart the computer; Windows should re-install any devices as necessary (but might prompt for driver software).
WARNING: exercise caution, particularly with removal of sound, network, and non-plug'n'play devices; devices in these categories might be shown dimmed as if not present but are nevertheless needed for the parent device to function correctly.
