I'm sitting here next to my iPod (4G, 4.3.1 JB) trying to use iRecovery on it but no matter what I just get this output from CMD:

iRecovery - Recovery Utility

Thanks to pod2g, tom3q, planetbeing, geohot and posixninja.

No iPhone/iPod found.

No "got USB" message either. iTunes recognises my iPod (in recovery, not DFU) and need to get it back up (need to set autoboot variable)
Please help!
