It should not take so much time to get a channel... In other drivers there was some GPIO problems, but I never got anything similar with this card (at least nobody told me)...
You can try to load the dvb-core module with a specified timeout in parameter: dvb_override_tune_delay:0: normal (default), >0 => delay in milliseconds to wait for lock after a tune attempt (int)
Since you're a beginner in linux you should; first connect your card,
then as root unload the modules used by your card (order is important);
sudo rmmod dvb_usb_dib0700 dib7000p dib7000m dib3000mc dib0070 dvb_usb dvb_core
If you want you can get a list on the used modules and dependences between them running; lsmod | grep dvb
Then you need to reload the modules in opposite order adding the parameter;
sudo modprobe dvb_core dvb_override_tune_delay=10000
You should see the new parameter on /sys/module/dvb_core/parameters/dvb_override_tune_delay
And now you have to finish loadding the other modules one by one; sudo modprobe dvb_usb... sudo modprobe dib0070...

Hi Sid, everything looks nice on the dmesg. The usb line numbers depend on the hardware order, so it's not a problem, and the line registering the interface must be there (it's when /dev/dvb is added, so if it's not there you can't comunicate with the device). I think the other usb modules should not give you any problem... If you modified in some way the source code it would be nice to post it, just to have a look. You should also try latest firmware (I think there was a 1.2 version which fixed som i2c problems).2009/1/3 Sid Gale <sid@xxxxxxxxxxxxx <mailto:sid@xxxxxxxxxxxxx>>
And finally I just prefer to use kaffeine that v4l-apps... but that's just a matter of taste.
Also try with the small antenna included with the device, I don't manage to get signal from an amplified antenna in linux while the "small and crappy" one works perfectly.
I'm using the information in the V4L-DVB wiki to try to get an Asus My
Cinema U300 mini usb dvb-t tuner working with eeebuntu (based on Ubuntu
Intrepid) on an eeepc 900. I have these lines in kern.log:

These match the information given in the wiki for 'Successful

me, 5-7 and 8 in the wiki) and the very last line 'usbcore: registered
new interface driver dvb_usb_dib0700'. This last line does not appear in
the wiki entry for 'Successful initialization' but does appear in the
two of the 'failure' entries.
When I try to scan for channels, using the dvb_apps package as described
in the wiki, I get this:
------------------------------------

WARNING: filter timeout pid 0x0011
WARNING: filter timeout pid 0x0000
WARNING: filter timeout pid 0x0010
dumping lists (0 services)
Done.
--------------------------------------
The tuner is connected to a roof-mounted aerial and when plugged in to a
Windows system pulls in 35 channels.
I'm very new to Linux and have no idea how to proceed, so I was hoping
that someone here could give me some pointers. I have noticed that in
the dmesg file there are lines saying:
-----------------------
Warning! ehci_hcd should always be loaded before uhci_hcd and ohci_hcd,
not after
------------------------
All the lines referring to ehci_hcd do, in fact, come after the ohci_hcd
lines so it would appear that I have the order wrong. Would this make a
difference and, if so, how do I correct it?
I'd be very grateful for any help anyone can offer.
Hi Albert
Thanks for your reply. I've tried the new firmware and with the supplied aerial, but with no different results. I haven't changed any source code - at present I wouldn't know how, I'm still learning. I understand, though, that the eeebuntu kernel is a modified one called the array kernel, if that makes any difference. I tried Kaffine and Me TV first and found that neither could detect any channels, which is why I decided to try the dvb utilities from the wiki. Thanks for the suggestions, though.
Can anyone give me some advice on how to find out why I get the 'filter timeout'? Is it because there is no filter to be found, or because there is no signal from the tuner, or because no channels are found within a given time...? If it's the last of these then it isn't trying for long enough, as it takes a minute of so for the first channel to be found on a Windows system and the filter timeout occurs after a few seconds.
Regards
Sid
