Hi again Anas. Well I wasn't sure if USB2 devices would work on a mobo that
only had USB1.1, but looking at the hardware forum at www.linuxquestions.org,
apparently they do, but obviously not with the USB2 transfer rates.
I also found a bit of info on ohci-hcd, uhci-hcd, and ehci-hcd, which I didn't
know before. Both ohci-hcd, and uhci-hcd are for USB1.1 controllers on the
mobo, but I don't know how they differ, and do know that for getting my usb
midi keyboard working on one of my distros, I had to specifically load
uhci-hcd. The ehci-hcd appears to be specifically for USB2 controllers, and I
verified that by looking at lsmod on a new machine that I've just built which
has USB2, and both ohci-hcd (USB1.1), and ehci-hcd (USB2), are loaded.
Going back to your MSI DigiVox A/D TV card, I found this link on Google, which
seems to be saying that you need to load some firmware, to get the card
working. Now I don't know anything about loading firmware, but the link with
details is below.

Scroll down a bit to where it says:
"Some users will need a firmware file to make their devices work.....", and
you'll see that the MSI DigiVox A/D needs firmware version2
Scroll down a bit more, and there's a link to where to get the firmware from.
Some of the stuff on the page I've provided the link to above, may not be
necessary, and it's for using the TV card with Kaffeine, not xawtv, or
tvtime, but it does appear that you have to load firmware for your TV card.
This may not be much help, but see how you get on with it.
All the best.
Nigel.
btw: If the card is not too expensive, and available in France, I might buy
one, and give it a try on both a machine that only has USB1.1, and my new
machine that has USB2.
