Heya,

The first patch fixes a few typos.

The second one requires the openobex patches I posted to the list, but
should fail gracefully if the support does not exist.

The dependency on openobex itself should probably be upped as well.

Cheers

Subject: [PATCH 2/2] Add USB support to osso-gwobex

Pass a "usb:busid,deviceid,interface" string to
gw_obex_setup_dev() to setup a USB Obex device.

Then you can access the FTP service as normal.
