I have Compaq Presario desktop model SR1103WM-NA430. When I plug a USB device into the front port I get an error message that there is not enough power for the device. It happens with devices such as my thumb drive, my digi camera, cell phone, and other types of small devices. It has worked fine in the past, but, as of a couple of months ago is stopped working. I have been trying to trouble shoot it based on various suggestions but, so far nothing works. I am hoping someone might have had a similar problem who could share their experience with me that might help resolve my problem.

Go into Device Manager and locate the Universal Serial Bus Controllers. Look for the hubs and then open it up and look at the power TAB. Typically USB ports are limited to 500 ma but it's possible to overload the entire hub. Check each hub and see what you discover. If you are using XP then this might not be available. There is a bios update available for your PC that you might consider if you don't already have it installed.
Disconnect all of the USB devices other than the keyboard and mouse if they are USB. Now try your thumb drive.
You might consider opening up your PC and remove and replace the USB connectors that are on the edge of the motherboard. Sometimes connection points will develop into a high resistance connection and by removing and replacing the connector might make a better electrical connection whick permits more current flow.
The other thing that you can try is to buy a power hub which might work or a PCI USB port card.

Well...I have tried all the suggestions and still get the error message. I also cleaned everything inside and out with canned air and my computer vac, and nothing seemed to help. Even the simple little devices that little power triggered the error message. So, I am going to assume that the USB unit itself is no longer good. I now have a 7 port USB power hub that I will try out with my cell phone and camera and see it it will work with them. This will be using a USB port from the back, which, hopefully, should work OK.
Will let you know what happens.
