You could install openssh server on your device and could then transfer files to and from the device with sftp. For example I'm using KDE on my desktop machine, so I can just type in sftp://user@192.168.1.102 in Konqueror, and I'll get to my files. I think the device had no password for the user account by default, so you might need to set it with the passwd command in xterm first. openssh I think is available from the extras repo.
