My PC has 5 USB connections. 4 are in the back of my computer, and one is on the front as part of a multiple card reader (SmartMEdia, CompactFlash, etc.) Recently, I've been getting messages about "over-current change" when booting. Now, my printer and my USB powered speakers don't work (aRta and ALSA say they can't find the sound device, which is /dev/dsp AFAIK). dmesg puts out the following:

I'm at my wits end. I've been working on this for 3 days and I can't find any useful advice anywhere that's worked. Any suggestions or is it a physical problem that spells the death of my USB ports?
My worst realization has come to pass. The problem ended up being a power supply problem. The motherboard was shutting down my USB ports to protect what was attached to them. Power could still get through, but no data. So, chalk this one up to physical trouble. Real trouble, as I had to get a whole new processor in the end, with a new power supply and motherboard. Took a while, but at least I'm back in action. EOF
I am experiencing the same trouble with ma system.......is there any way to overcome this??all the USB drives are not sending or recieving data...only power is there...
