Patch : enhance usb detection

[Frederic Crozat <fcrozat mandrakesoft com>]

The following patches is from Mandrake 9.0 package of gnome-pilot..

It is needed because on our system (which are using hotplug), there is a
big time slot between /proc/bus/usb/devices initial modification (ie
when hotsync is pressed) and when /proc/bus/usb/devices contains the
"Palm handheld" string which is used by gpilotd to detect hotsync has
been pressed..

Second part of the part is a big hack needed on Mdk 9.0 system because
we are using devfs and /dev/ttyUSB* doesn't exist until visor module is
loaded.. (should be replaced by checking if /dev/.devfsd exists and
therefore, discard the /dev/ttyUSB* test..)
