Today my v2 decided it no longer will power up from a usb port (tried 3 different computers). The dlc must be connected before it will power up.

all that lights is the green led on the far right.

Is there a common failure in this unit that can be repaired or do I always have to connect to a dlc to get enough power to run the v2 from now on?

With DLC connected, can the EFILive scantool/tunetool see the V2...?

I pm'd tech support.

When you plug it in to the USB port does windows give the 'bing bong' sound?

Cheers,

did you try a new USB cable?
my EFILive USB cable developed a short in it recently.

If it still fails, contact Ira (http://forum.efilive.com/member.php?u=416).

tried 3 different cables

if i plug into the usb port WITHOUT dlc connected flashscan screen does not even flicker and the green led on the right comes on steady

once i connect the dlc the computer goes bing bong and flashscan lights up and works correctly

I had a similar problem.
The USB port protection (USB6B1) chip had popped.
The earth had gone open circuit, so it would only power up if you connected it to the car.
