Hello Mikki,
PCI Serial Port and PCI Simple Communication are devices from your motherboard. It could be a PCI device but not your Smartphone. Can you please provide a screenshot of the Hardware IDs of these devices?
- Open Device Manager
- Expand 'Other Devices' Category
- Right click 'PCI Serial Port and PCI Simple Communication', on popup menu select Properties
- On popup window, click the Details Tab
- On Details Tab, click the dropdown box, select Hardware ID and provide a screenshot.
Also, can you please provide me the exact model of your Samsung Laptop or PC you are using? You may check the model in the label at the back of your machine or using dxdiag.
