1850 + - hfc_usb_init :
1851 + is the main Entry Point for the USB Subsystem when the device get plugged

1854 + the device (hfc_usb_disconnect) are published, as the id_table
1855 +
1856 + - hfc_usb_probe
1857 + this function is called by the usb subsystem, and steps through the alternate
1858 + settings of the currently plugged in device to detect all Endpoints needed to
1859 + run an ISDN TA.
1860 + Needed EndPoints are
1861 + 3 (+1) IntIn EndPoints (D-in, E-in, B1-in, B2-in, (E-in)) or
1862 + 3 (+1) Isochron In Endpoints (D-out, B1-out, B2-out) and 3 IsoOut Endpoints
1863 + The currently used transfer mode of on the Out-Endpoints will be stored in
1864 + hfc->usb_transfer_mode and is either USB_INT or USB_ISO
1865 + When a valid alternate setting could be found, the usb_init (see blow)
1866 + function is called
1867 +
1868 + - usb_init
1869 + Here, the HFC_USB Chip itself gets initialized and the USB framework to send/receive
1870 + Data to/from the several EndPoints are initialized:
1871 + The E- and D-Channel Int-In chain gets started
1872 + The IsoChain for the Iso-Out traffic get started
1873 +
1874 + - hfc_usb_disconnect
1875 + this function is called by the usb subsystem and has to free all resources
1876 + and stop all usb traffic to allow a proper hotplugging disconnect.
