First thing you have to do is find where syslinux is installed. The best way to do that is look for a file named vesamenu.c32. You can use locate, find, or any other distribution specific tool for that. In Debian (and its derivatives like Ubuntu, LMDE etc.) this file is under /usr/lib/syslinux, so I'll just use that for the following code.
+ +cd syslinux
+for f in *.c32
+do
+cp -v /usr/lib/syslinux/$f .
+cd ..

In either case, unmount the device and delete the mount point (directory).

If, for example, you want to increase the device scan delay to maximum, the above commands would become:
mkdir /mnt/usbdevice
-mount /dev/sdc4 /mnt/usbdevice
+mount /dev/sdc1 /mnt/usbdevice
cd /mnt/usbdevice
cp sysresc.cfg sysresc.bak
sed 's|scandelay=5|scandelay=10|' sysresc.cfg > sys.cfg
mv sys.cfg sysresc.cfg
-cd; umount /dev/sdc4
-syslinux /dev/sdc4
+cd; umount /dev/sdc1
+syslinux /dev/sdc1
reboot
If, in addition to that, you had to use the boot parameter usbstick, then it would be:
mkdir /mnt/usbdevice
-mount /dev/sdc4 /mnt/usbdevice
+mount /dev/sdc1 /mnt/usbdevice
cd /mnt/usbdevice
cp sysresc.cfg sysresc.bak
sed 's|scandelay=5|scandelay=10 usbstick|' sysresc.cfg > sys.cfg
mv sys.cfg sysresc.cfg
-cd; umount /dev/sdc4
-syslinux /dev/sdc4
+cd; umount /dev/sdc1
+syslinux /dev/sdc1
reboot
In case something goes wrong with your new settings, you can always rename sysresc.bak to sysresc.cfg, either from linux or Windows.
