Hey guys I don't know how to fix this ..

If I leave anything USB in while I reboot ie. external hdd and dvd burner they all get really slow maybe down to usb 1.
Second if I leave my printer,external and usb dvd burner in when I reboot my usb keyboard and mouse lock up and I have to do a hard reboot. It really burns to have to unplug everything but the keyboard and mouse. Anyone else have this problem ?
