Hey, I have had some trouble trying to get a new KWorld 399U dual dvb-t USB dongle working with my debian etch 64-bit (+mythtv) box [1]. Physically dissasembling the dongle reveals the four chips on board are labeled AF9013-N1, FA9015-N1 and 2x MXL5003S. I have found and followed instructions on linuxtv.org for building the latest v4l drivers[2] with some modifications[3]. I have also found that the 399U has recently had support added[4]. Building and installing from the latest source[5], restarting and trying `modprobe dvb-usb-af9005` tells me I need firmware. Adding an image to /lib/firmware[6] solves this issue. I then reboot and this now detects as /dev/dvb/adapter0 and works well with mythtv though the channel changes are a little slow. Only one of the two tuners is working for now, I am guessing this could be because of the firmware image I chose to use. I have the windows driver disk that came with the tuner and have read suggestions that the firmware image can be extracted from it. I tried using AF15BDA.sys file from the x64 driver dir as /lib/firmware/dvb-usb/ad9015.fw without success. dmesg shows the driver continually trying to load the firmware. A second issue is that the computer already has a working KWorld pci tuner which uses the cx88 drivers which are not compiled when building the af9015 checkout. The files seem available, but the modules are not being build. My existing kernel modules are not compatible (I backed up then rm -rf /lib/modules/`uname -r`/kernel/drivers/media/* before doing `make install`, restoring my backed up video/cx88 dir and contents throws unknown symbol errors when trying `modprobe cx88-dvb`). I tried `make all cx88-ivtv` in case that was relevant, but this doesn't seem to help (possibly because the link is dead v4l/cx88-ivtv.c -> ../v4l_experimental/cx88-ivtv.c but this doesn't exist). So two questions: What can I do to enable the second tuner on the dongle? How can I compile the cx88 drivers along with the rest in the af9015 checkout? If there's any other output or info that may help, please let me know. cheers, Owen.
