Thanks Glen and Gary for your responses. I am also a Spectrum customer 
in the LA area.

Unplugging/replugging the Firewire cable on the Arris box did produce 
dmesg output:

[34408.459191] usb 1-2: USB disconnect, device number 3
[34408.459352] hdpvr 1-2:1.0: device video0 disconnected

and now plugreport sees something:

Host Adapter 0
==============

Node 0 GUID 0x00080008000802e5
------------------------------
libiec61883 error: error reading oMPR
libiec61883 error: error reading iMPR

and there is now something at /dev/fw0:

crw------- 1 root root 240, 0 Jul  4 09:46 /dev/fw0

but 6200ch still fails the same way:

$ 6200ch -v -v -g 00080008000802e5 2
couldn't set port: Invalid argument

I don't know about that 'S400' at the end of the dmesg display, or how 
to alter the vendor id.

Thanks in advance for any further troubleshooting clues.
