Hi, After some testing I have made the following discoveries: * My card is identified as DTT-CI by dst_get_device_id * The problems from dmesg doesn't seem to be a timeout. If I read 10 bytes from the answer from the tuning string instead of 8 (FIXED_COMM) I get a complete message with a correct checksum in the end. However, even though the tuning seems to go ok, dst_get_signal returns returns the string '0x0 0x0 0x0 0x0 0x0 0x2 0xff 0xff' which is not appreciated by the driver. * So, reading 10 bytes instead of 8 looks a bit like a card with DST_TYPE_HAS_NEWTUNE. So, I tried setting DST_TYPE_HAS_NEWTUNE. This however, gave another problem. Since the request string for frequency tuning changed, so did the answer. An answer that the driver interpreted as an indication that the tuning failed. Can anyone with more experience of the drivers draw any conclusions from the logs below? I'm a bit curious of the messages sent to the card. 00 06 00 00 00 00 00 fa is an identification reqeust 00 05 00 00 00 00 00 fb is a signel request so, the second(and first?) byte(s) seem to be some kind of primitive id. However, this is different when setting the frequency. For non NEWTUNE card f1 f2 f3 00 bw 00 iv ea (fx=frequency, bw=bandwith, iv=inversion) is used and for NEWTUNE cards, the same, but with a two byte header is used. These two bytes are 09 00, which could be primitive id, if it is two bytes. How have you deduced the different messages? By trial and error, by debugging the windows driver or by some other mean? Ok, now finally to the two logs: Reading 10 bytes instead of 8 in dst_get_tuna: ============================================== May 14 09:56:35 thay kernel: Set Frequency = [522000000] May 14 09:56:35 thay kernel: dst_write_tuna: type_flags 0x52 May 14 09:56:35 thay kernel: dst_comm_init: Initializing DST..
