[KLUG Members] Sniffing scsi traffic to/from scsi device driven from a virtual machine

[greenproc]

I'm trying to get more information about how a windows driver is communicating
with a scsi device (scanner to be specific), to assist further development of
the sane-project.

My approach is to run windows on a vmware virtual machine, and then use a linux
utility to watch the scsi bus.  Which utility to use I'm not sure, and given the
fact that I'm bound to have choices after doing some research, I'm hoping to get
some feedback from anyone who may have useful suggestions.

It has been suggested to use strace, but I'm not sure what to strace.

Another suggestion is to use in-kernel debugging, but if there is a simpler way
that would be better; unless in-kernel debugging is easier than it sounds.

Thanks in advance for any help :=)
