* The Microsoft Wireless Intellimouse 2.0 sends one extra leading
* byte of data compared to most USB mice. This byte frequently
* switches from 0x01 (usual state) to 0x02. It may be used to
* report non-standard events (such as battery life). However,
* at the same time, it generates a left click event on the
* button byte, where there shouldn't be any. We simply discard
* the packet in this case.
*
* This problem affects the MS Wireless Notebook Optical Mouse, too.
* However, the leading byte for this mouse is normally 0x11, and
* the phantom mouse click occurs when it's 0x14.
