|Did you restart your machine for re-detecting the USB ports & hub, just in case the ports were removed/uninstalled from Device Manager ?|
If you suspect it is a BIOS thing, go into BIOS ( how to go into BIOS depends on the M/B model and make ) and browse within the tabs to locate USB descriptions. They are mostly self-explanatory.
If you see Disabled next to USB descriptions in the BIOS, make them Enabled. You may see several of them, such as USB 2, USB, Legacy USB, etc. Just read the directions as to how to enable/disable the settings. They are mostly down or by the BIOS pages.
Hope the above helps.
