check the metal sheathing where the cord goes into the plastic housing....
on mine the shrink wrap on the usb wires slid up so everytime the sheathing came in contact with something i would lose the device....(wiggling cord while driving, movement from clutch foot)
no wonder ecuExplorer would just stop, reading the debug console everything is good then all of a sudden it would stop reading...retrying over and over again....
i am so glad this never kicked off while reflashing.... that would've sucked....
this is a 1.2 plug by the way...
oh i just wrapped some electrical tape around it, now i can wiggle it every which way and all is fine....
