You can quickly fix it by:
1) Modify adb_usb.ini file by adding 0x1949 to the bottom of vendor IDs
$ pico /Users/uki/.android/adb_usb.ini (replace "uki" with your user name)
2) verify that you have made the change correctly:
$ more /Users/uki/.android/adb_usb.ini
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x1949
$
3) Reset ADB from Eclipse (drop-down arrow on the right hand side of "Devices")
Device should be showing in "Devices" view now.
NOTE: after updating Eclipse Help -> "Check for Updates" you will have to repeat this procedure.
