1873 + Here, the HFC_USB Chip itself gets initialized and the USB framework to send/receive
1874 + Data to/from the several EndPoints are initialized:
1875 + The E- and D-Channel Int-In chain gets started
1876 + The IsoChain for the Iso-Out traffic get started
1877 +
1878 + - hfc_usb_disconnect
1879 + this function is called by the usb subsystem and has to free all resources
1880 + and stop all usb traffic to allow a proper hotplugging disconnect.
