RE: [WinDbg] 1394 not working on my new debug system

There is lots of 1394 hardware out there with which WinDbg will not work. I
encountered the same thing last month with my brand spanking new Dell
Precision M4500, which I made sure had a 1394 connection. It didn't work,
and it is the first Dell system I have owned that 1394 would not connect
with my target. The saving grace was giving OSR ~$30 (no they do not have a
senior discount) for their PCMCIA connector which does work. I was seeing
the same messages with the onboard 1394 connection.

Subject: [windbg] 1394 not working on my new debug system

I have been using 1394 as the debug connection on the target system for
quite some time.
Recently my debug system died and I am interested in switching to a laptop.
I was forced to purchase a new 4-6 1394 cable for the laptop because I
previously used a 6-6 1394 cable between two tower systems.

I plugged the cable into the 1394 port on the laptop and the target system.
I started up the x64 version of WinDbg and attempted to connect.

I saw this:
Wrote 0 of 1 bytes of the breakin packet.
Failed to write breakin packet to target. Win32 error 0n2
WARNING: The HOST cannot communicate with the TARGET!
Wrote 0 of 1 bytes of the breakin packet.
Failed to write breakin packet to target. Win32 error 0n2
WARNING: The HOST cannot communicate with the TARGET!

Is this merely a confirmation that my new cable is bad?
I checked the 1394 settings on the target system and it seems to be fine.

Is there something else obvious that I may have missed?

thanks,

John
