How to get the Epson BT 200 (Moverio) listed with

Question

My Epson BT-200 does not get listed for adp when I execute the command:

adb devices

To fix that problem I followed the steps of this question. Unfortunately without success.

lsusb

prints out the following line for my device:

Bus 002 Device 081: ID 04b8:0c06 Seiko Epson Corp. 

So I edited my "/etc/udev/rules.d/99-android.rules" file and now it looks like this:

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", ATTR{idProduct}=="6860", MODE="0666", OWNER="tokam"
SUBSYSTEM=="usb", ATTR{idVendor}=="04b8", ATTR{idProduct}=="0c06", MODE="0666", OWNER="tokam"

But the restarting of udev (and even my computer), replugging of the bt-200 usb-cable and the restart of the adb-server does not lead to a listed device.

What can I do to get the device listed with adb?

I checked on the device, USB-Debugging is enabled. It is turned on, and the password is entered, so it got mounted as a disc-drive.
