For those with cssu stable installed who don't want to install testing can do it like this:

First go to this site (link below) and then press on the cssu testing icon and let ham/app mngr open.

http://wiki.maemo.org/CSSU

Say yes to intalling the new repo and let that finish. then close ham/app mangr and open up xterm and write these codes:

sudo gainroot

apt-get install mceledpattern

apt-get install ke-recv

then download the usbmode .deb file and install with this:

sudo gainroot

dpkg -i nameof.deb

That should do it without installing testing. anyway it worked for me

Regards Dousan...

e: a notification about a new cssu update will appear ignore that.

e2: disable the cssu testing repo after you're done installing usbmode...
