Yes, but if you look again you see that the legacy driver does define it, and even includes the description of bits 9 -> 19 And the legacy driver source code has always been more reliable then the datasheet, so I would put my money on the code. ;) > Would it be possible to verify with Ralink that this is not a typo in > the RT2500 datasheet? I'll see what I can find out. Ivo
