Re: DigiVox A/D TV-Tuner issue
I probed the module v4l2-common, but with no effect. The /dev/video0 can't still be accessible as it seems (even with xawtv, it gave the same error message content). Perhaps the problem is a usb-interface problem (even though the module uhci-hcd is loaded). The USB ports in this laptop are version 1.1 and it may be the cause that the TV-Tuner is not identified as a video source. I may try it on another PC having USB 2.0.

Hi Anas. First I must say that I didn't realise it was a USB TV card, and I
don't have much experience of USB stuff (my tv card is an Hauppauge wintv
express PCI card).
Anyway, that said, I compared your lsmod with the deps listed for the em28xx
driver in modinfo, su to root and run modinfo em28xx, to see for yourself.
Now I didn't expect to see some of these in your "lsmod | grep video, but
v4l2-common should be there. As I say I'm not familiar with USB TV cards, but
all these modules should be loaded automatically when you either boot with
the device plugged in, or when you plug it into a booted machine.
One module I did have to modprobe though, and that was for my USB midi
keyboard was the "uhci-hcd" host controller interface driver, and
subsequently added it to /etc/modules, so that it would be loaded
automatically. There are a couple of others as well "ehci-hcd, and ohci-hcd",
but only the uhci-hcd shows in my lsmod.
If you look at your lsmod, I'm sure at least one of these should be loaded for
USB devices to work.
I've never had any success with tvtime, and use xawtv. If you have that
installed, run as user, xawtv -hwscan, both with the tv card unplugged, and
plugged in. It doesn't give much info, but should show the video device that
your tv card is using, if all the necessary modules are loaded.
I can't think of anything else at the moment, but gives you a bit to go on
If the only tool you have is a hammer, you will see every problem as a nail
