I just updated my Original Droid to a Droid 4 (awesome phone!). I bought an HD dock to charge the Droid 4 and dock it to my laptop. After hooking up the USB-to-microUSB cable from the laptop to the HD dock with the Droid 4 in it, the Droid 4 doesn't charge and the laptop doesn't see the Droid 4 as a device. This is different from the the way Original Droid with it's dock worked. Has anyone else seen this behavior? Is there a fix for it, so that when I dock the Droid 4, the laptop sees it and it recharges?
