The Gigaset 3070 isdn is the ancestor of a family of ISDN DECT base stations allowing the connection of a PC via USB or DECT. This project is building the Linux support (drivers and frontend utilities) which Siemens neglected to provide.
Java access to USB, currently using kernel 2.4 Linux-USB support. There is a "core" API for accessing USB devices, and simple tools including a USB viewer in Swing. Applications are being developed separately, including digital camera support.
