Power Surge on Hub Port

Power Surge on Hub Port

A USB device has exceed the power limits of its hub port.

 

This error message began popping up recently (no recent hardware or software

changes). Message appears even if there is nothing connected to a USB port,

and if a wired or wireless mouse is used. It occurs both on wake-up from

standy, and on start-up.

 

I have tried re-setting the port (as recommended), but the message reappears

after a few minutes. Disabling USB 2.0 seems to work (as recommended by

Microsoft), but that's not a solution!

 

Googled the error message, but no luck there either even though it looks

like a very common problem. Some people suggest removing Service Pack 2, but

not sure what the downside is of doing this.

 

Any suggestions appreciated.

Re: Power Surge on Hub Port

 

All electrical devices when first powered on exhibit a condition called

"InRush Current". This is a momentary spike in current drawn which

diminishes ( or levels out ) after a short period of time. With NO USB

devices connected this would indicate a hardware failure. You need

to open the details box of each USB root Hub in Device Manager &

check the Power (TAB) to see what if any current is being consumed.

This doesn't show you the actual current consumed, only what the peripheral

has negotiated with the host.
