Debug Android Wear Device over USB

Question

Is this possible to debug wear device over USB, not Bluetooth? By Bluetooth it is possible, but when i'm connecting watch to PC via USB, in adb i have:

adb devices
List of devices attached
????????????    no permissions

Answer 1

I use Ubuntu 14.10 as OS and had to run these steps to get my Wear recognized (source: http://developer.android.com/tools/device.html, under step 3):

1. Get your Wear's vendor ID from here: http://developer.android.com/tools/device.html#VendorIds
2. Log in as root and create this file: /etc/udev/rules.d/51-android.rules
3. Add this line, and replace ???? by your Vendor ID:
   SUBSYSTEM=="usb", ATTR{idVendor}=="????", MODE="0666", GROUP="plugdev"
4. Save and execute chmod a+r /etc/udev/rules.d/51-android.rules
5. Reconnect your Wear, and wait for the Permission-Dialog to show (on your Mobile!)

EDIT:

here is a complete 51-android.rules file to allow any kind of android device

Restart ADB with root privileges.

sudo killall adb
sudo adb
