Could you send us the complete dmesg log, including the portion where

You say that you are using 188.8.131.52, but the log below makes it seem to
me as if you are in fact using the newer version of the driver from
You see, in the 2.6.16 version of the driver, all bluebird devices will
show a -110 error. This error is negligible, as it actually doesnt
cause any harm to the device's functionality... The point is, the error
is missing, and this makes me think you are not running the older
version of the driver in 2.6.16. Either that, or there is something
above this in your dmesg log that you aren't showing us.

Quite interesting... If I were to take a wild guess, I would assume
that the mt352 demod in the usb portion of the device has been replaced
by a zl10353 ... Chris, do you know anything about this?

Attached is a patch that you can test. This might fix the problem for
you. If your device works after applying this, then please let me know,
and I'll have it merged into the main tree.
Unfortunately, this patch will not apply against a vanilla kernel, due
to the dvb tuner refactoring that just got merged into master.
You should not use the master branch right now with your cxusb-bluebird
device, since a bunch of dvb-usb modules are broken right now in the
Andrew de Quincy has already fixed that problem in his ~quincy/v4l-dvb tree.
So, you'll have to clone Andrew's tree and apply this patch against it.
(unless his tree got merged by the time you receive this message)
Things should work for you if you use this tree + the attached patch for
your testing. Please let me know how it turns out.
...and I should mention, this is just a guess -- you could be
experiencing an entirely unrelated issue. This is, however, worth a try.
I hope this helps,
