While waiting for Kailang's answer (and I hope he'll get the solution!!),=20 isn't it possible to grab information from Windows? I'm sorry I don't know= =20 very well how Realtek chip works but if the problem would comes from some=20 registers which are not well initialized isn't it possible to dump the stat= e=20 of the realtek chip and its registers under Windows and compare it with the= =20 one under Linux? Because I'm not sure that revers engineer the Windows driver would really=20 easily lead to the solution. Thank you again for your help. Aur=E9lien
