6 You can now shut down the system cover.Turn off the computer, attach the cover mounting screws.You can connect to the system unit all disabled devices.If the USB-connector does not work and the computer does not recognize the flash drive, so you are not tightly pressed to the controller slot or poorly documented.You must repeat the installation.

If the port problem is repeated often, check the registry «LowerFilters» parameters or «UpperFilters», they should be removed.Open the registry, find the HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Contro l \ Class \ {36FC9E60-C465-11CF-8056-444553540000}, remove the specified parameters.This registry change operation is dangerous to carry out, if you are an inexperienced user.Trust the experts.
