I have the v2 and it has been working great. today I was doing some data logging, I unplugged the v2 from my laptop and truck. when I go to plug the v2 into my laptop again it will not do anything. it doesn't connect and the v2 screen stays dark and no lights flash or anything. it will work if I plug it straight into my truck though. any thoughts?
sound like usb cord if trashed
also if I can get some clarification, ive been reading more on here about plugging the v2 into a laptop that is plugged into the vehicle, if I do this will the v2 literally go up in smoke? and can I also trash the v2 if I plug my laptop into a wall outlet? my laptop doesn't have great battery life that's why im wondering.
If there are multiple ground paths between laptop and vehicle, then there may/will be a problem with ground potentials being different (causing a large current to flow... V2 may get hit).Quote:
