I'm having problems and I think I need drivers, but cannot find them. I have an hp d530 small form factor PC, and I deleted my usb drivers I think (long story, screwing around with attempting to connect my razr & similarly named drivers). I cannot use my usb ports anymore, but they DO provide power (when I plug in mp3 player, it charges). I've tried drivers from the internet sites, but none have worked. Can someone point me in the right direction/tell me what I'm doing wrong?
