Problems with WinTV Nova T by Hauppauge USB-stick (id: 2040:7070)

Hi,

a view days ago I bought a dvb-USB stick from Hauppauge (WinTV Nova T). I want to use this stick with linux, but I sill have some trubble. After a google-search it is clear, that the correct driver is dib0700, and the firmware to use is dvb-usb-dib0700-1.10.fw (md5:
5878ebfcba2d8deb90b9120eb89b02da)
Kernel is 2.6.25

lsusb:
2040:7070 Hauppauge

If I want to tune to a channel (e.g. with kaffine) the dmesg-log is overcrowed with "DiB0070 I2C write failed" and there is no sucessfull tuning. The output of kaffeine while searching a channel is:

Using DVB device 0:0 "DiBcom 7000PC"
tuning DVB-T to 402000000 Hz
inv:2 bw:0 fecH:9 fecL:9 mod:6 tm:2 gi:4 hier:4
. LOCKED.
Transponders: 1/63

Invalid section length or timeout: pid=17

Frontend closed
Using DVB device 0:0 "DiBcom 7000PC"

inv:2 bw:0 fecH:9 fecL:9 mod:6 tm:2 gi:4 hier:4
. LOCKED.
Transponders: 2/63

Invalid section length or timeout: pid=17
.... <and so on>

The output of dmesg while attaching the stick and searching with kaffeine and debug enabled is:

Hi,

a short summary after a few weeks testing:

The internal EEprom seems to be broken. I returend the stick to the shop and got my money back.

Best regards

Robert
