A trick with drivers that you are having trouble with is to delete it's entry in the Device Manager and reboot.
Rebooting can cause MS to install the device with the reboot.
It's worth a try.
If that doesn't fix the issue, try rerunning Slim Drivers.
How are you updating the driver ? I would download it to your desktop and run the .exe but try uninstalling as suggested then try the install.
Hi, sorry, lost you at delete the entry, how to delete at device manager? After deleting, how do I download and reinstall? Many thanks to you guys!!
