adb doesn\'t recognize my Nexus 10 on Windows 7. Here\'s what I\'ve done:
I started with the same problem as you, but managed to get my adb connection working on a Fedora 16 system as follows:
Inserted 0x18d1 into adb_usb.ini (I do not bother with the device ID)
Inserted the following extra line into 99-android.rules. It's not the quite the same as yours but I leave you to experiment.
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev", OWNER="johnp"
Pressed the settings->about->version number 7 times.
Rebooted tablet and noticed that a new section is created in settings called "developer options".
Enabled USB debugging in settings->about->developer options.
On Fedora performed adb kill-server.
On Fedora performed adb start-server.
On Fedora performed adb devices.
I now see a new USB device in the list. When I go to my development environment (Eclipse) I see the device there as well.
