ok you know that silver chip? in the controllers it's eliptical. it's also tagged with "24.000" somewhere on each of the silver chips. at first i thought crystal since it's a 2.4ghz system, but that doesn't make any sense why it'd be in the wired and the mem card. that's why i figured this was the security chip. upon further investigation i learned that there is the same chip labele "24.000" inside of a device called the "medusa," which is a unit hidden under the 360 through which the xbox 360 is controlled in store displays. it only has 2 contact points. if anyone has any ideas or thinks this could help, i may have come across an extra medusa.
