Hi Ken,
I'm not following this too well. Maybe it was described
in your first email.
devices.before shows Dev# 3 as a compact flash reader.
Do you unplug it (from the root hub ?) and plug in the monitor's
hub (to the root hub?) or is there yet another external
USB hub involved here also? (since devices.after shows Dev# 3
as a hub device)
Also, your kernel messages file shows:
May 22 23:28:01 neon kernel: usb.c: USB disconnect on device 3
May 22 23:28:07 neon kernel: usb.c: USB new device connect, assigned device
number 3
May 22 23:28:07 neon kernel: hub.c: USB hub found
so it looks like the hub is being detected, but something fails
quickly after hub detection. Can you set the console loglevel
to 9 and repeat the monitor-hub connection (plug-in) and post
that portion of the kernel log file? (Use Alt-SysRq-9 if you
have Magic SysRq key enabled. You can also boot linux with
the 'debug' option [as in: linux debug] if you don't want to
build a kernel with Magic SysRq key enabled.)
I'm trying to locate a monitor-hub to test this also, but
no luck yet (internally).
Thanks,
Randy
