Logitech Mouseman Dual Optical defaults to 400cpi

[Chris Faherty <rallymonkey@bellsouth.net>]

I'm not sure which list to write about this.  I've written Logitech but they 
gave me back a non-answer.. something about clicking some options with their 
Windows software.

The Dual Optical mouse has a sensor(s), Agilent ADNS-2051, which is capable 
of 400cpi (default) and 800cpi.  Logitech decided to leave this setting up 
to the driver software, and so the mouse defaults to 400cpi and 100rps 
(report rate, which is 200rps max) if you use a generic HID driver.  Even on 
Windows if you don't install MouseWare, you will only see 400cpi.

I can't find any information on how to switch it into 800cpi mode.  I have 
hooked it up to a Windows machine with their MouseWare driver and used 
usbsniff to log what happens during a hotplug.  But I don't know what I am 
looking at, I don't understand USB communications.

Can someone suggest a remedy?  Here is a portion of the USB sniff log which 
writes to the mouse during hotplug:
