Hi Jaak,
Thanks for your answer.
I've compared the two INFs (the one from Dell that is working and the one that is found by Windows on the pack)
It seems that the one provided by Dell is a newer version :
DriverVer=03/11/2005, 5.10.00.4255 (vs DriverVer=11/11/2004, 5.10.4251.0)
However, the one from Dell doesn't seem to support as many HWIDs than the current one and seems to lacks supports for the VIA, ALI ones etc...
I wonder where the one from the INF came from to support so many devices.
Anyway, I'll try to do as you say tomorrow and come back with the results, but I am concerned by dropping these drivers as well as I would have liked my CD to be as universal as possible. Someday I may encounter these devices the new driver dropped if I simply overwrite it.
The best solution would probably be to get our hands on the new driver version that is also containing the other devices, I guess?
That said, I'm very new to these driver packs and I'm not really sure what is possible with them or not, so I'm sure you'll have a better solution or suggestion.
Thanks.
