hi,

I am working on DVB-T for the first time. I am using a Pinnacle PCTV 2001e
USB DVB-T dongle.In that the device dri vers are getting registered and the
device is getting detected.I am using a 2.6.23.15 kernel.

The dmesg is as follows:

dvb-usb: Pinnacle PCTV Dual DVB-T Diversity Stick successfully deinitialized
and disconnected.
usb 1-1.4: new high speed USB device using musb_hdrc and address 4
usb 1-1.4: Product: PCTV 2001e
usb 1-1.4: Manufacturer: PINNACLE
usb 1-1.4: SerialNumber: 12020607

dvb-usb: found a 'Pinnacle PCTV Dual DVB-T Diversity Stick' in cold state,
will try to load a firmware
dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.10.fw'

But, after that when i am trying to run any scan application , it is showing
"scan failed".

the dmesg after running scan application is,

APPLN INFO >> Inside scan_network
