Novacom is the service to transfer files or get a shell on the pre.

Note that the devnum is 0x0103, compared with 0x0101 on the Pre. A diff between the two lsusb outputs shows mostly minor differences, except that the Pre seems to have one additional input endpoint, 5. The diff output follows the lsusb output. <source lang="text"> Bus 001 Device 057: ID 0830:0103 Palm, Inc. Device Descriptor:
