<div dir="ltr">Thanks Mark, but the error I have is connecting to the PicKit 3 in the first place -- ie just for the IPE/IDE to see the programming device itself - before even getting to executing the programming of OVMS ? So 12V wouldn't be relevant until that point?<div>
<br></div><div>I tried uninstalling/reinstalling the MPLABX software with no effect, so I still can't figure out how to regain connectivity with the programmer on my main desktop. odd, very odd. This is currently using windows, v2.10</div>
<div><br></div><div>A little debug suggests it's a USB related issue. I'm using windows 8 and notice that the programmer is now showing up as "unknown USB device (Device Descriptor Request Failed). </div><div>
Umm..</div><div><br></div><div>I removed all the devices under the root hub - cleaned up the error - still didn't work</div><div><br></div><div>Then plugged into my monitor (which *may* be a powered hub) - found the pickit3 fine.</div>
<div><br></div><div>Umm, windows and the wonders of USB.. power related, but I think USB for the programmer itself, rather than just the power for the end device board</div><div><br></div><div>But at least it's not OVMS or the programmer... learning this stuff! Eventually may get around to looking through the leaf code (out tomorrow tho)</div>

I did note the module was very warm - sat on the centre console, but I think this was just as the car was in bright sunlight....<br>

> My gut feel is it's a combination of needing to reset the ovms (in the car it does at least still power up) it seems, just is uncontactable, & a problem with the programmer since I should be able to connect without a device attached - and potentially use the on-the-go programming support<br>
