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.

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: usb 1-6: new high speed USB device using ehci_hcd and address 6 usb 1-6: configuration #1 chosen from 1 choice dvb-usb: found a 'Hauppauge Nova-T Stick' in cold state, will try to load a firmware dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.10.fw' dib0700: firmware started successfully. dvb-usb: found a 'Hauppauge Nova-T Stick' in warm state. i2c-adapter i2c-0: SMBus Quick command not supported, can't probe for chips dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
