I recently purchased a mini dsg reader and while trying to read my tcu it keeps saying...

''READ SESSION FAILED USB DEVICE ERROR (H008)
ERROR REASON :USB DEVICE COMMAND NEGATIVE RESPONSE
ECU COMMUNICATION ERROR (E049)
ERROR REASON :DATA DOWNLOAD REQUEST REJECTED BY ECU''

WHAT AM I DOING WRONG...?
I AM CONNECTING STRAIGHT TO THE GEARBOX
2006 VW JETTA 2.0TFSI
Thanks for your time
