Hi daphantom. I had my winmodem working succesfully in my mandrake 9.1, but it was not easy for a newbie as I am!. I'm afraid You are using a driver from linuxant.com, isn't it?. For your question #1 I can only supose that is for security reasons. Only root can manage installations and some configurations OK?. Question #2 As you can se at:
http://www.linuxant.com/drivers/hsf/limitations.html this driver does not support fax currently. You can join a mailing list to be aware of new versions of the driver. Feel free to ask any question about installing procedures.
