dunno. lol wow those voltages are really wacked out. I recommend buying a new power supply, and replacing teh CMOS battery. (Silver Oxide, or Lithium Ion 3.3v) try this power supply


Newegg.com - ENERMAX Noisetaker II EG495P-VE ATX12V 485W Power Supply 115/ 230 V - Retail

EDIT>> Actually, first, remove the main power connector from the motherboard, and check it for damage (melted plastic, blackened, etc etc)

you sure?

the power supplie?
hmmm...
even 4 a small flash drive/

Hey brustlhr,

Can you give us a clear picture, of what devices are connected all together (including USB hubs powered/unpowered), and where they are connected to. Which ones are working, and which are not?

You mentioned your mouse works fine. What happens if you plug your mouse into a port that doesn't work for your other devices?

what it sounds like, is that the USB ports are getting enough power for a low power device like a mouse, (they only use like 10-25milliamps whereas Flash drives/external hdds can use up to 500milliamps. like i said, check the Main power connector for signs of damage, then follow madmonkeys instructions

That was my thoughts exactly, since each root hub can only supply a max of 500mA in the first place. The only solution in this case would be to purchase a powered USB hub.

You maybe right about those voltages, but to be honest they give me a headache between boards and cpu types. I try to avoid them where possible. If it is the power supply that is causing these problems, then I'm sure we can confirm it another way.

Those error messages only occur when Windows has problems communicating with those devices. I believe software has been well and truely exhausted. If it's not a power issue, it will be interesting to know if it's specific ports that are the problem. Again, a hub would sort the problem out as it can be connected to the working port (currently used for the mouse), to supply ports for the rest of your devices.
