+ *  Description:
+ *	This is a quick hack to parse logs from the usbsnoop (usb sniffer)
+ *
+ *  Settings:
+ *	If needed to process a huge log maybe is needed to increase
+ *      the php settings.
+ *
+ *          $ vi /etc/php.ini
+ *            memory_limit = xxM
+ *
+ *  Usage:
+ *         $ php ./usb_snoop ./Usbsnoop > output.txt
+ *
+ *  Example:
+ *
+ *	   009279: 002309 ms 126080 ms c0 0e a0 00 00 00 01 00 <<< 00
+ *         009280: 000007 ms 126087 ms c0 10 a0 00 00 00 01 00 <<< 00
+ *         009281: 000005 ms 126092 ms 40 0e a0 00 00 00 01 00 >>> 99
+ *         009282: 000107 ms 126199 ms c0 0e a0 00 01 00 01 00 <<< 99
+ *         009283: 000015 ms 126214 ms c0 0e a0 00 10 00 01 00 <<< 99
+ *         009284: 000004 ms 126218 ms 40 10 a0 00 00 00 01 00 >>> 00
