-+
-+   - hfc_usb_probe

-+      settings of the currently plugged in device to detect all Endpoints needed to
-+      run an ISDN TA.
-+      Needed EndPoints are
-+      3 (+1) IntIn EndPoints   (D-in,  E-in, B1-in, B2-in, (E-in)) or

-+      function is called
-+
-+   - usb_init
-+      Here, the HFC_USB Chip itself gets initialized and the USB framework to send/receive
-+      Data to/from the several EndPoints are initialized:
-+       The E- and D-Channel Int-In chain gets started
