Have you restarted your computer after receiving Code 32 error? If not then do it immediately because sometimes it can be caused by Hardware temporarily. If you are facing this issue after the installation of any device then undo your changes and restart your computer. If you are still facing the same issue then you should delete the UpperFilters and LowerFilters values in registry because the corruption of these two values often creates this issue. For doing the same,open registry editor and navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Class".Then click on + icon to expand it. You will see a long list of subkeys but you should focus on "{4D36E965-E325-11CE-BFC1-08002BE10318}." and delete the filter values.To avoid this issue,make sure that you are using the latest drivers for your device.
