Hello!
I was running previously a windows 10 64bit. Don't know why but my USB port stopped working. Looking into the device manager I found that PCi port and PCI Serial Port Controller had a yellow indication mark on it.
I reinstalled windows to windows 7 64bit so that the lost drivers must be self installed but nothing happened. While trying to update PCI Port driver I accidently uninstalled it.
Please help how can I reinstall that and fix both issues. I really need help because I have very much use for usb ports for transferring media in mobile phones. USB is working but no mobile is connecting. It charges but is not displayed in File Explorer.
Help! Anyone?

Hi Muneeb Ahmad,
Try installing the chipset drivers for your system and see if it helps:
Hope it helps,

Hi, @Muneeb_Ahmad
For the PCI serial port, you need this driver...manually install the driver if the auto install method doesn't work.
This package contains the Intel Local Management Service (LMS) and Serial-over-LAN (SOL) support for Intel Active Management Technology (AMT) for the supported desktop models and operating systems. This software is part of the Intel Digital Office Initiative.
