If it's for mac then you can open terminal and type in following.
echo 0x05e0 >> ~/.android/adb_usb.ini
0x05e0 is the Vendor ID for the TC55.
Once done, restart your adb.
cd your_path_to_adb
./adb kill-server
./adb devices
You should see your device in the list.
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
132665216D0010 device
If not, try unplug the device and plug-in and do ./adb devices again. It just worked for me few minutes ago ;)
!!! dont forget to do all this again each time you update your ADB..
