I have an iPod and lately a message keeps coming up saying "power surge on hub port: a usb device has exceeded the power limits of its hub port. for assistance in solving this problem, click this message.

All I have plugged up to my PC is an external HD (250gb which holds all my songs) a printer, speakers, all the basic stuff...

Would this call for me to beef up my hub power? Thank You
 
You can't "beef up" your USB power. Perhaps spread it out, or use a USB hub that allows for DC input...

Now what on your computer is USB? I mean you technically can have speakers that are USB powered, mouse, keyboard, etc etc... Are you like that? Obviously, unless it's connected to the USB port, it's not going to steal power from it...

Have you tried different USB ports, or spreading out the load, if you do have lots of devices connected to say a single USB hub...

what is DC input?

As far as I know, the speakers, kb, mouse, ipod, external are all usb powered


I tried to plug in my external hd to the usb again and it was working fine, but then my kb and mouse would work...

Im sorry if this makes no sense, I am not really familar with this sort of thing and I really appreciate your help, thank you
 
dc input is power from a wall plug. speakers cannot be in a usb port. do you have a usb hub? how many things are plugged in on the hub? if you have an open usb port on the computer, plug in the ipod to it and see if the message goes away

I'm pretty confused. I have a tower and it has 3 usb outlets (1 in the front and 2 in the back)...I really dont know what a hub is or anything.

Im sorry if I sound like an idiot
 
ok, a hub is an extra device that you plug into an existing USB port, this converts it from one port into multiple ports (usually 4). You can them plug in another 4 devices, because you have 4 more ports.

Do you have one of these devices??

Oh and no, you dont sound like an idiot, i understand perfectly that for someone who doesnt spend 3/4 of their life inside a computer it can be a bit confusing at times... dont worry about it, we're here to help.

So yeh, do you have a hub?? If you dont then the error message you are getting is referring to the "internal hub" this is basically where all of the normal ports spur from, you cant see this one but it is still idnetified as a hub.

If you do not have an external hub then the cause for this "power surge" is most likely that your PSU (Power Supplyy Unit) is flaggin behind when you put the ports under full use. This can be rectified only by purchasing a new PSU, which in your machine might be tricky, retail companies like to use proprietary parts to stop end users upgrading and thus losing the company money...

Hope this all helps get back to us with some details, dragon :D
 
thanks a lot for that post, it made me understand much more ;)

Anyways, I do not have an external hub. So it looks like I will have to get a new PSU. My next question is....what is the cheapest way to go?


Keep in mind that it seems if I plug anything into any of the USB ports it does not work...even just 1 thing (like my ipod)


Thanks again!
 
sorry man, i dont have any info to help, but it sounds like this e-machines might be faulty, if only one device doesnt work. When did u get this machine? maybe somethin went wrong with the motherboard, and its still replaceable by a warranty?

Does the ipod, and any other usb devices still work even after you get the message? maybe your computers just being stupid.
