Hi

I bought a Sansun Sky  Dream usb DVB-T box from eBay.
Under Windows it works, I can watch FTA channels.
Under Linux (Fedora 4, recent kernel 2.6.15-1.1833_FC4, x86_64) tuning fails.
When I plug in the box dmesg shows the following:

usb 3-2: new full speed USB device using ohci_hcd and address 2
dvb-usb: found a 'TwinhanDTV USB-Ter USB1.1 / Magic Box I / HAMA
USB1.1 DVB-T device' in cold state, will try to load a firmware
dvb-usb: downloading firmware from file 'dvb-usb-dibusb-5.0.0.11.fw'
to the 'Cypress AN2135'
dvb-usb: TwinhanDTV USB-Ter USB1.1 / Magic Box I / HAMA USB1.1 DVB-T
device successfully initialized and connected.
usbcore: registered new driver dvb_usb_dibusb_mb

lsmod shows this:
dvb_usb_dibusb_mb      18241  0
dvb_usb_dibusb_common    10053  1 dvb_usb_dibusb_mb

dvb_core               95997  1 dvb_usb

dib3000_common          3393  2 dib3000mc,dib3000mb

With dvbt-scanaid-0.03 I created the following file (I'm in Hungary
and we have a pilot service):
[root at cerka dvbt-scanaid-0.03]# cat Scanlist.txt
# Scanning list was created by Create_Scanning_Table by Johannes Bauer

T 714000000 8MHz 2/3 NONE QAM64 8k 1/8 NONE

When I try to scan  I receive the following:
[root at cerka dvbt-scanaid-0.03]# scandvb Scanlist.txt > channels.conf
