Just confirming.
The system is not recognizing the USB flash drive?
Have you tried different USB devices to see if the system detects them?
Keyboard, mouse, ETC
Since this is a laptop do you have a network cable that you can connect form the computer to the modem/router directly maybe this way you can access the internet and get the drivers.
There is a possibility that there is a driver needed to be installed for the USB ports to work. When looked the only USB was to update the 3.0 to the newer release.
Did you make any changes in BIOS I know with some systems that you can turn off (disable) some of the USB ports.
