ipod crashes winxp when connected

Ok my lovely girlfriend arrived with a nice present a few weeks ago: a 32GB Ipod touch.
Actually it's a closed box since now 'cause it's a 3.1.3 firmware which is not possible to jailbreak
so I cannot use it from linux, but hopefully for a short time.
Anyway I switched to windows and got itunes and then connected the ipod to one of my usb ports and got the BSOD (blue screen of death, if you dont know what it is stop reading this is not for you).

So I tried hardly to find out what the hell was going on and here is the problem and the solution:
the windows was using a Logitech driver which recogniesed the ipod as a webcam because of the presence of images and photos and when it tried to use the driver... boom !
If you are affected from this problem simply go to C:\WINDOWS\SYSTEM32\DRIVERS
find a file called : LVUSBSta.sys
and rename it like LVUSBSta.sys.ipodcrash
and everything is ok. If you then need to use a Logitech web cam you can use the newest logitech drives...
voila'

cheers

ADDON:
I tried to delete the driver file, but I just got many yellow exclamation marks in device manager - complaining that the registry was corrupted or something alike. Ok, that meant that the driver was installed as a "filter driver", or the like. That can be checked in the "Details" page of a device, selecting one of the "filter" entries from the drop-down box. And here it was LVUSBSta.sys driver, installed as a "lower class filter". Windows "filter drivers" are drivers that insert themselves above or below another one so that it can see (and modify) data sent from/to the other driver. If a filter driver file is deleted, Windows won't start the device.
Well, time to clean-up the registry then. I looked for the driver in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SW, and removed all the entries related to that driver.

    I had troubles even after deleting the previous keys and I found out that these 2 contained a LowerClass key with the infamous LVUSBSta

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}
