yes,yes you can.
AN XBOX 360 has 2 front USB ports, and 1 back USB port, an XBOX 360 hard drive will work for sure. A USB flash drive will work on the xbox 360 after you get the Spring 2010 Dashboard update
if it is a usb keyboard then yes you plug it into the usb ports if it isn't usb it wont work.
No. I am not sure what types of USB models work but you can buy a special USB for xbox.
NO, the xbox 360's controllers are wireless and usb, unlike the xbox which is a different connector.
Plug in your usb keyboard to one of the ports on your xbox (360 only), and anytime your in the xbox dashboard with the virtual keyboard (this is the keyboard that appears on screen when sending instant messages, ect.) you should be able to use it to enter text.
Xbox 360 has only ethernet port.Modems with USB or COM interface can't be connected to xbox 360.
No it will not because the 360 controller is and can be wireless and plugs in via usb while the original xbox controller does not.
no. you have to buy the xbox 360 wireless adapter. unless you mod the consle
yes, if ur luckly you can get xbox live if you dont have it
I rotate it 180 degrees.
put the firmware from your PC to a usb then connect the usb into the xbox360
