I am not getting anything in the USB devices list to add to the filters.

Fair enough. So I tried to remove network manager and got hit by this:

$> sudo aptitude purge network-manager network-manager-openvpn
network-manager-pptp network-manager-vpnc  knm-runtime
The following packages will be REMOVED:
  knm-runtime{p} network-manager{p} network-manager-openvpn{p}
network-manager-pptp{p} network-manager-vpnc{p}
0 packages upgraded, 0 newly installed, 5 to remove and 12 not upgraded.
Need to get 0 B of archives. After unpacking 6,512 kB will be freed.
The following packages have unmet dependencies:
  network-manager-gnome: Depends: network-manager (>= 0.9.2) but it is
not going to be installed.
The following actions will resolve these dependencies:

     Remove the following packages:
1)     gnome
2)     gnome-accessibility
3)     gnome-core
4)     gnome-desktop-environment
5)     network-manager-gnome

I am not sure I can go ahead with this, don't want to lose the whole
gnome stuff!
