Did you check the little box to remember that you authorized your computer for adb access? Also, adb in recovery is a different driver. If you use wugfresh toolkit it walks you through fixing it. Something like control panel, device manager, find yellow exclamation mark, update driver, select from computer.Downloaded OTA file. Got USB debug enabled, allowed my computer forever. While 5.0.2 is running ADB finds the device and all is well. When I get to recovery my device is not found. Any idea what I am doing wrong?

After second attemtp to update through system update, failed again with "system partition has unexpected contents - E:Error in / cache/recovery/block[dot]map - (Status 7)"
I know it will be painful, but you might try a factory reset before trying again.
