[coldsync-hackers] linux, usb, palmos 4.0, 4.1

["ed" <spied at yandex dot ru>]

i  need to sync several palmos 4.0 and palmos 4.1 devices with linux box via
usb.
palmos 4.0 devices (sony clie 320, palm m500) works with protocol 'serial',
palmos4.1 devices (palm m500 with upgraded palmos, i think all other) with
protocol 'net'.

i make quirk patch to libpconn/netsync.c from cvs tree and now 'net'
protocol work (as i think) with any palmos4.x device

diff -r1.22 netsync.c
