has anyone managed to get a freecom dvb-t usb2 going properly?
Everytime i tune the device to try to watch tv the device restarts and
the tuning program ( tzap ) says the device has a positive lock on the
signal.
But if i ctrl-C tzap to attempt to re-start the process the system will
either hang or cause an OOPs to occur. If an OOPs occurs the process is
show in device wait status.
Attempting to use another program to do this ( such as xine ) terminates
itsself and causes an oops.
Has anyone got this device going on there machine, If so what kernel
were you using and if possible with what options. I am using slackware
10.1 with kernel 2.6.15.4.
this is the oops i got when using xine to acess the device:
dvb-usb: found a 'WideView WT-220U PenType Receiver (Typhoon/Freecom)'
in warm state.
dvb-usb: will use the device's hardware PID filter (table count: 15).
DVB: registering new adapter (WideView WT-220U PenType Receiver
(Typhoon/Freecom)).
DVB: registering frontend 0 (WideView USB DVB-T)...
input: IR-receiver inside an USB DVB receiver as /class/input/input4
dvb-usb: schedule remote query interval to 300 msecs.
