It's crappy coding on the part of the Logitech module.  Ross Ridge gives
a convincing argument for what's going on:
<http://sourceforge.net/mailarchive/message.php?msg_id=17999960>.  More
info on the loader lock issue is in this paper:
<http://www.microsoft.com/whdc/driver/kernel/DLL_bestprac.mspx>.  Now if
only someone could forward these clues to the idiots that wrote that
Logitech crapware, it would save a whole lot of frustration.
