It seems to work now, but weird weird weird ...!

At first, the dump in dmesg (that I have posted before) suddenly changed the following line:
=> bt878_probe: card id=[0], [ NULL ] has DVB functions

At this point I am not sure about the exact message, but it looked more or less like that. "My card has died on me" I thought. Several reboots, with or without power on/off made no difference.

Then, in despair, I decided to install it in a Windows XP machine, only to see if it would work, with the supplied driver CD. Driver installation seemed to start well, but then install rebooted the machine, and after that it complained that there was no card in the PC ! Dead like a doornail, I thought.

Just for the sake of it I put it back in my Linux machine, started the drivers and ... lo and behold !! It works ! dmesg now suddenly lists a lot more info than ever before, and /dev/dvb/* files are being created by udev.


Probably modules didn't get unloaded properly and hence didn't get loaded properly, but that's when your reboot helped.


No, I had rebooted many many times in the same situation.

Could it be that the Windows install program has written something into the card eeprom that was necessary to make it work ?!


No, nothing of that sort is possible.


I think that my card is flaky.

After some reboots, it works fine. But after other reboots it cannot find the tuner, and fails. Once it even crashed on trying to load the drivers (stuck during boot on loading dvb-bt8xx).

A broken card might also explain why card id=[0], [ NULL ] suddenly showed up. This problem persisted after reboot (even with power-off).

Has anyone seen the same kind of flakyness with this card? It could also be a hardware design problem of course, or it could have to do with the kernel version I am using (2.6.17.5)

By the way, the card now also works (*if* it works) when I pull in all the drivers by a simple 'modprobe dvb-bt8xx' (most of the time), without any special parameters etc.

Thanks for the great support, will keep you posted.

Z.
