I'm sorry if this is a little late, but I had once had access to a Z6
and believe I had it successfully connected to my Linux host, and was
therefore puzzled by this message exchange.
I have now borrowed the device again for the weekend to check it out a
little more.
Using Alan's patch below, otherwise my kernel is a standard 2.6.23-rc5
(CONFIG_USB_STORAGE_DEBUG=y ) I got the following result after reboot
and connecting the Z6.:

What I can't understand, however, is that as this mobile phone
supposedly runs Linux. I can't see how Motorola could break it so badly
that the USB connection now doesn't work with a PC running Linux?
And you say that this seems to be a more widespread problem with
Motorola devices? Do you remember which ones, and do they run Linux as well?
The following is from connecting a Z3 that supposedly isn't based on
Linux, but works all right (and this may have been the one I thought was
the Z6 that I claimed worked):

I hope perhaps it can provide some comparison info now with a device
that works and one that doesn't.
If Motorola actualy has made changes to the Linux kernel they use with
the Z6, I suppose we should be able to get the actual code. Should I
investigate that?

sdb and sdc appear in /proc/partitions, but trying to access with 'fdisk -l` or
'mount' freezes the phone.
I uploaded the debug-log to:
<http://www.akoenecke.de/moto/usb_debug2.txt>
The debug-log included 2 spontaneous reboots and 1 freeze (in this order) of
the phone without unplugging.
The resets and disconnects occurred because of yet another bug in the
phone. It reports that sdc has 128673 sectors, but in fact it probably
has only 128672. The error occurred when the computer tried to read
the (non-existent) last sector. The phone failed to follow the proper
protocol for reporting an error, so the computer reset it.
It's not surprising; other devicees from Motorola have the same bug.
The patch below ought to help. However considering the number of other
bugs and problems in this device, it's not clear how far you should try
to push it...
