after switching in Devmode the WebOS quick install doesn't see the device, it asks to connect the divice befor running the quick install but nothing happens when I re.connect the device to my pc.
try re-installing the novacom drivers fro quickinstall. Restart the completely before plugging in in to the PC.
Jason has developed a Universal Novacom Installer. You may want to try that.
good point. I forgot about that!
