Unable to mount iPhone

[dataworx22]

I'm running Knoppix 6.7 off a 4GB USB stick on an Acer Aspire 5520 laptop. My iPhone is a 3GS on iOS 5.1.1, jailbroken. On connecting the phone via USB it is recognised by File Manager, but I get error report 'Unhandled Lockdown error (-4)' Below is Terminal output:

knoppix@Microknoppix:~$ lsusb | grep Apple Bus 002 Device 005: ID 05ac:1294 Apple, Inc. iPhone 3GS
knoppix@Microknoppix:~$ sudo mkdir /media/iPhone
knoppix@Microknoppix:~$ sudo ifuse /media/iPhone/ -s Failed to connect to lockdownd service on the device. Try again.

If it still fails try rebooting your device. knoppix@Microknoppix:~$ I think I'm missing a fundamental step or is this an iOS constraint? Can someone here help me to connect this device? All I need to do is manipulate audio and photos
