Alrighty guys, i have been having this weird usb connection problem for a while now, but have not gotten the chance to ask. Well the problem is that my usb will not connect. I have a 12" powerbook 1.5ghz. I have tried connecting the external harddrive but it would not show up on the desktop. I have also tried connecting my psp..and that wouldnt work either. The cable i am using is brand new...and has been working fine. Anyone else running into the same issues?
