I have a somewhat similar problem with my Compaq Presario 3140 AMD64 
laptop and my 64-bit SuSE 10 .  If I plug and unplug my cellphone (which 
looks like a dialup modem, utilizing the module cdc_acm) a few times, my 
whole USB system just dies.  No hotplug events are recognized from any 
USB device (not just the cellphone) until I reboot.  I have not tried 
the 32-bit kernel.  Upgrading to 2.6.14 from the apt-get did not fix the 
problem.

Can hardware be excluded as a cause for these problems?
