Hi, I noticed today that my internal webcam for my Acer laptop was not working. I tried reinstalling the webcam driver but an error always pops up saying that the webcam can not be found. Later I noticed when I plugged in my flash drive, phone, etc, these were not detected either.
In device manager the webcam was not listed, and I didn't spot any unknown devices and searched for hidden devices.
However there is a (!) near 2 "Standard Enhanced PCI to USB Host Controller"s under USB Controllers. I right clicked to update drivers and windows said my drivers were up to date, but nothing worked still. I uninstalled the drivers and rebooted, and when windows tried to automatically update drivers they failed.
Under device status is says:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
Thanks for any help to get my devices recognized again.
