Windows 7: USB Ports Not Working

USB Ports Not Working

Last night I was transferring some files from my laptop to my external hard drive and everything was working fine but then a couple hours later, I went to plug in some rechargeable USB batteries that I have and noticed that they weren't lighting up. I then tried plugging in several of my other USB devices but none of them were connecting either. Also, I was transferring the files between my Xbox and updating my Ipod at the same time so I was connecting and disconnecting a lot of times over that short period of time and I'm not sure if that might be an issues? I've tried several other solutions after Googling the issue but none of them have worked so far. Here's a brief summary of what I've tried:

- Restarting the computer. (However, I did notice that if I plug in the batteries after restarting the computer they do light up for a split second and then instantly fade away.)
- Turning off the computer and disconnecting all power sources and re-starting.
- Checking device manager and checking for driver updates and re-installing the USB controllers. It said that they were up to date and there are no exclamation points beside any of the controllers.
- Running the sfc/scannow tool. I didn't find any integrity violations.
- Doing a system restore back to a couple days ago when they were working fine.
- I ran a full virus scan with Microsoft security essentials and it didn't find anything.
- The only thing that has even remotely given an inclination of an error is this fix it tool I downloaded from microsoft support and it says "Hardware changes might not have been detected. Windows Update configured to never install drivers" and "Change Windows Update settings - Not Run" but when I check my device installation settings, the automatic update option is ticked and when I manually check for updates, it says they are up to date. So maybe I do have a virus or malware? I'm just not sure.

Thanks in advance for any help you can give me.

Hello Kutter mate the batteries you haven't mentioned the size they are and I am if you have put a bit too much strain on the USB ports to deliver.

They're just AA plug in ones and I've had them for a while now and it's never been an issue in the past.

Edit: They appear to be working again for the moment. I had put my computer in sleep mode over night and just logged back on and tried connecting my tablet and it's showing up now so maybe my problem fixed itself.

sounds like your pulling more than 500ma on the port your using does windows give you a power draw warning when charging them? like this, and is your laptop on AC while doing this with power savings off? just asking the needed questions i doubt that is your issue as you have done okay with it before.
