I was trying to find the old Macintosh software SCSI analyzer program, and came across
this (unrelated other than they were
analyzing USB SCSI traffic)
http://vusb-analyzer.sourceforge.net/
Looks pretty cool for analyzing USB traffic.

I have always used a hardware analyzer such as a LeCroy USBTracer whenever
I have needed to look at USB traffic. For some things you need to see what
is actually happening on the bus.
This software tool might be interesting for looking at some things at a
higher level.

New subject: Telebit modem card
I found an old Telebit modem card. I believe it is a Traiblazer, nota Trailblazer+. I was
wondering if anyone had a list of the commandset for it.I can find the Traiblazer+ on the
web but not the original Trailblazer.I realize it is a superset of the orignal but need to
know what changed.The card is unusual, in that it has a 68K, a TMS32010, MC2661 andthe
8250.I would guess the 8250 is just for the bus interface ( PC board ) andit used the 2661
for serializing data.It looks like this may have been the orignal ADSL concept. It was
saidto use 512 channels, each with a maximum speed of 6 baud, in the PEP mode.An
interesting modem.Dwight

Hi Cindy I think I've seem most all of these. The problem is they are always
talkingabout the Trailblazer+ and not the original Trialblazer. I have a completelist of
the Trailblazer+ but need to know which commands were missing ordifferent for the
Trailblazer.Thanks for the effort though.Dwight

Software like that works fine as long as all you need to see is
the stream of bytes and the sequence of transactions. For all
of the reverse engineering stuff I've done on USB protocols,
that's been quite enough. This also looks a little nicer than
the $80 commercial stuff I was using in 2003.
If you need to analyze things like signal quality and raw bit
timing, then yeah, I guess you need something external. Most
of the software ones can see everything the OS sees coming

This software tool might be interesting for looking at some things at a

mean
that if you're debugging a device that's having problems, say,
in the enumeration phase, this won't be of much use.
