+ * 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
