Hi Guys, Its seems the latest updates to Windows 7 have shut down my USB Printing Support port on a Dell Laptop. I've tried a system restore but that didn't work. How can I restore my original USB port? This is the error code 52 from the device manager: "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)" Would appreciate any help! Thank you!
