If the controller plugs into a USB port, yes.
No it is no problem and a recommended method to charge the controller. I also put mine into my Sony BR6 HDTV USB port to change the controller because it is always on unlike the PS3 USB port that shuts off when the PS3 does.
Typically it is a usb port 2.0.

you have to get the wireless gaming adapter that you hook up to your computer via a USB cable. then you can use your controller with your computer.Yes, you can use a controller charger in the USB port
You can plug any USB device directly into either controller port. Alternatively, you could plug any USB device into the slot above the ethernet port on the back of the Xbox 360.
Make sure you have it plugged in the USB port and also have a controller plugged in a controller port.
Hmm.. sounds odd. Maybe it needs to be charged, if you have tried to do that and have not been successful through the PS3 usb port, try and charge your PS3 controller through a computers usb port?!
If you are using a wireless controller you cannot use it with your computer. If it is a USB controller, simply plug in the USB head into a USB port on your PC and all drivers will be preinstalled on a Windows machine. Before you use it, please configure the keys that the controller will use.
I have a Nyko iType2 PlayStation 2/3 compatible dualshock controller, that has both the port for the PlayStation consoles and a USB connector for your computer.
