Hi,
Another way of controlling the numbering schema of your DVB
devices is to blacklist the modules (so udev doesn't load them)m and
then modprobing them manually at system startup. This is what I did
for my Nova T-500 and Avermedia A700.
Briefly (this is for Gentoo, running OpenRC):
In /etc/modprobe.d/blacklist:
blacklist saa7134 # for Avermedia A700
blacklist dvb_usb_dib0700 # for Hauppauge Nova T-500
And in /etc/conf.d/modules:
modules_2_6="${modules_2_6} dvb_usb_dib0700"
modules_2_6="${modules_2_6} saa7134"
This way, udev doesn't load the modules automatically at startup,
which was causing a different reordering of the DVB devices on reboot
and from a cold boot (due to the delay caused by firmware loading on
the Nova-T). The modules are loaded sequentially now, and in the order
specified in /etc/conf.d/modules.
Best regards,
Eduard
PS: I doubt this hardly solve your firmware problems, but at least it
might help you with device ordering.
