Hello,
just sharing my recent experience regarding usb device installation.
I tried to install a usb printer... printer not detected... did all the advanced steps with no luck
Finally i reinstalled windows, then the usb printer installation succeeded following the regular steps.
My conclusion: I had installed something before the printer that conflicted with it...
Next time I run into problems installing a device, I'll give it 30 mn and if it doesn't work, reinstall windows.
