 I have recently been trying to get my Sony Clie' 760 to work with
Linux, also.  I am using coldsync 2.2.2 and kernel 2.4.13-ac3 (it
didn't work with 2.4.12, either).  I am not using devfs.  When I
attempt to sync, I get a segfault from coldsync and the following
messages from the kernel:

 Everything still works fine with my USB Visor.  One of the things
that caught my eye is "Sony Clie 4.0 converter".  Unlike the 710,
the 760 runs PalmOS 4.1, rather than 4.0.  Perhaps this has
something to do with it??

 Please CC me on replies.
