WIRED!!!!!!!! Guitar won't sync with Xbox 360?

SOURCE: rockband 360 problem

have you checked the batteries? also try re-syncing them to the 360. are you using wireless or wired? if wired, sometimes the usb ports get worn out, try using the one in the back above the av port. good luck!

SOURCE: how do sync the guitar w/ xbox 360 console?

Start the game and go into the options menu. There is an option to calibrate lag. Complete the instructions and the guitar will be synchronised with your TV.
If you mean how do you assign a guitar controller to the console, press the small button near the headphone port after pressing the guide button to turn the controller on, then press the small circuar button on the front of the console like you would with a regular 360 controller to assign the controller to the Xbox.

Step one: Hold the Xbox button on the controller for 5 seconds
Step two: click the connect button on the xbox.
Step three: Hold the connect button on the controller for 5 seconds.

If they are not broken, this should work. This is the PROPER way to connect ANY wireless controller.

Dude your probably thinking about the Break away cord Or the cord that pulls out before the USB cord for your xbox 360, the guitar comes with 2 parts The guitar with a cord and the breakaway extender the Extender plugs into the front of the Xbox in a little Usb slot :)
