perhaps the usb sniffer just shows the setup packet in the return data? i mean, all those values are listed in the going down part:
Request = ff Value = 8440 Index = 0000 and then later in the coming back part: SetupPacket : 21 ff 40 84 00 00 40 00 i dont think the setup packet actually comes back. can you try looking for a firmware file on your windows box that looks like these data blocks? allan On Tue, 1 Aug 2006, Tabor Kelly wrote: > I feel like I understand almost all of what is happening in this log: > http://tabor.taborandtashell.net/sane-fs2720u/turned_on.LOG > > However, I don't understand any of the Setup Packets with the bmRequestType > of 0x21.
