Hello,
Is there anyone who has the Digital Devices Cine CT (or S2) working under esxi with device pastrough?
The card is working perfect under linux direct, but I have some weird problems with linux (ubuntu 12.04) under esxi.
I get the folloing error message:

Code:

I can see /dev/ddbridge. But /dev/dvb is missing.

Does anyone has a possible solution for this?

Are you sure you have the proper drivers for it? I have that card and the drivers were an absolute pain in the ass to install. And yes, you really need the out-of-tree drivers, even with Linux 3.10 (what I'm using at the moment).

Negge,
Thanks for your answer. I have tried different drivers from linux-media-dkms linux-media-experimental-dkms, and building drivers from linuxtv.org. But that makes no difference.
But after some hours of searching, I found the solution. MSI/MSI-X is cousing the I2C timeout. So I needed to disable MSI/MSI-X. I have done that by adding pci=nomsi to grub.

Code:

in /etc/default/grub change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
into:
GRUB_CMDLINE_LINUX_DEFAULT="pci=nomsi quiet splash"
and then run:
update-grub
And reboot.

The 2 tuners are now available. Haven't tested them for a longer time, but they seem to work normal now.

Great! I've had my tuner for about two weeks and haven't had a single problem yet (haven't rebooted either).
