Hi,
I had make install a module for a dvb usb box which writen by my= self. But this one didn't have real frontend ops and tuner ops.These funct= ions did nothing but return 0.
Like this
static int demo_fe_init(str= uct dvb_frontend *fe)
{
    return 0;
}

Afte= r the usb box removed from linux, the DVB system called demo_fe_release and= demo_tu_release, sofar that seems very good=A3=A1 But, I can't rmmod this = module normally. It showed "ERROR: Module dvb_usb_dvbusb_demo is in use".Th= is error is diffrent with "ERROR: Module dvb_usb is in use by dvb_usb_dvbus= b_demo"

How can i rmmod this module with out reboot Linux.

th= anks
