Rather than that ... Can you get one of the drivers from xusa http://www.usa-x.org/forum/modules.php?name=Downloads (Unfortunately they are kernel version specific e.g. the kernel with RH 7.1). Also, I'm not sure they actually work :( (actually, it wouldn't take much to emulate the driver) Then use strace. strace doesn't help much with ioctls, so to improve the information add/replace with the contents of http://members.optushome.com.au/jhonan/dst/dst-strace-ioctl.tar.gz to the source of strace. With strace, only bother with open,close and ioctl. Also be sure to follow forks. In any case, I reckon what you'll see is 1. the DST-CI coming back from the driver. 2. a big fat 0x14 / 0x15 ioctl which is some sort of read / write to the CI module. That will be the beast! Simple to say, tedious to do. > I'm also having an interesting dialog with twinhan at the moment.. > More to follow as things unfold. Dialog!? Biting tongue to prevent screaming.
