Capi4Linux and capi4hylafax

Hello, world I had a problem with my Hylafax-server on SuSe7.0 I had installed my Fritz!Classic with the drivers from AVM-Homepage(capi4linux and capi4hylafax). But now when i change my i4l to AVM B1 PCI and want to restart it i get the error message: /dev/isdninfo no such file or dir. And the ippp0 device could not be found in /proc/net/dev The rci4l_hardware starts and capiinit also. But the isdnlog in kernel messages didn't recognize any incoming-ring and no outgoing calls are made. My hylafax-client on win9x tells me that the fax had successfully be send, but didn't really work!
