HELP: USB NOT WORKING

Hi,

I am currently using a powerbook g4 and one of my USB ports is not working. The USB port on the right side will send power to any device that I connect to it, but it will not detect that actual device. The left usb port works fine. What's happening?

Yes, my right-side USB isn't working even after reboot. (And it's not a 10.4 problem, since I'm on 10.3.9.) Applecare product specialist told me they have to replace the logic board. Third time I have to take this laptop in for repair since I purchased it in Oct 2003 (last 2 repairs were for replacing the screen). I really like Mac OS, but I'm beginning to doubt the quality of Apple hardware.

I've also had this same problem with external drives. Turns out the USB ports on the PBG4 don't provide enough power and the only way to make them run is either to plug the external drive to a power source or invest in a Y-cable to plug the drive to BOTH USB ports at the same time. This made it work. But I'm wondering if there is a way to boost the USB power source?

after taking the pbook to the genius bar at an apple store. it turns out my usb ports are completely shot. because they use the same bus, a blow out on one caused them both to die. so i need to send it in for service. the real scary thing that apple should be worried about is that my ipod w/color screen was probably the cause for it! it went dead at exactly the same time, and i mean DEAD. not like the sad face or the folder icon, this thing was not responding to firewire, usb, being plugged into the wall, anything. the "genius" at the store told me because he had never seen dead usb ports and the fact that the ipod was shot, he assumed it CAUSED the problem in the powerbook. hows that for compatibility??
