I'm going to update the wiki due to an error in mara's code that qwerty12 found. I think this is as easy as unziping and moving files around. See if you have any comments to add. I also created icons to reboot and sfdisk the SD cards, I'll add those to a future wiki on how to create application menu items.

To Install vi (or other editor)
1.a. If you have the right repository (anyone know which one?), a vi editor shows up as in Application manager - Tools -vim version 70 5.79 MB
1.b. If not, try http://www.cs.cornell.edu/zlt/maemo/vim_6.4-1_arm.deb (wouldn't install for me after uninstalling vim)

Before we begin, you must have vi [link] installed and be able to gain root [already covered above]

1. Launch x-term
2. vi /home/user/MyDocs/Otg.sh
2.a. press i to edit
2.b. paste code

Code:

#!/bin/sh
# usb otg mode script
# use gainroot to become root and relaunch itself
if [ `id -u` != 0 ] ; then
# if not already root, call itself as root
sudo gainroot <<EOF
$0 $*
EOF
exit
fi
echo otg > /sys/devices/platform/musb_hdrc/mode

2.c. press Esc (hardware key below d-pad, or on vi screen)
2.d. save by entering :w (: is next to capital L in shifted menu)
2.e. exit by entering :q
3. chmod +x Otg.sh

repeat for Host.sh with this code:

Code:

#!/bin/sh
# usb host mode script
# use gainroot to become root and relaunch itself
if [ `id -u` != 0 ] ; then
#if not already root, call itself as root
sudo gainroot <<EOF
$0 $*
EOF
exit
fi
echo host > /sys/devices/platform/musb_hdrc/mode

From this point you can use Status Bar mentioned below, personal toolbar and/or continue to make an Icon.

1. Launch x-term
2. sudo gainroot
3. vi /usr/share/applications/hildon/otg.desktop
3.a. press i to edit and paste the following code

Code:

[Desktop Entry]
Version=0.1
Encoding=UTF-8
Name=USB Otg
Type=Application
Comment=USB On the go mode
Exec=/home/user/MyDocs/Otg.sh
X-Osso-Type=application/x-executable

3.c. press Esc (hardware key below d-pad, or on vi screen)
3.d. save by entering :w (: is next to capital L in shifted menu)
3.e. exit by entering :q

again, repeat for host.desktop

Code:

[Desktop Entry]
Version=0.1
Encoding=UTF-8
Name=USB Host
Type=Application
Comment=USB host mode
Exec=/home/user/MyDocs/Host.sh
X-Osso-Type=application/x-executable
