It's a Pentium4 on an Intel chipset.

ALL intel chipset P4 mobos this defect: insufficient ESD protection on 
Southbridge's USB ports. Intel is to blame.

It means that sooner or later when you insert a USB device, something bad 
happens:
1)USB controller damage - it works somewhat, but has problems
2)USB controller burnout - it's seen by the system, but the connected devices 
doesn't
3)Southbridge burnout - motherboard is dead.

You have the 1st. It's going to progress if you try to use MoBo's USB ports. 
Disable USB in BIOS and use your PCI controller.
