[jp] What does this jpilot error message mean?

Hi,

I'm having trouble getting my Palm (Treo 700p) to sync with jpilot on my 
Centos system via USB.  When I sync, I get this error in jpilot:

pi_accept Illegal seek
Exiting with status SYNC_ERROR_PI_ACCEPT
Finished

Does anyone know what this error message means?  I'm trying to figure 
out what's going wrong, but I'm not having any success.

I have jpilot syncing fine with this Palm over the network, BTW.  For 
USB, I set things up for udev as described on various websites.  Here 
are the relevant ports & symlink (created and deleted automatically with 
each sync attempt):

lrwxrwxrwx  1 root root 7 Oct 17 09:09 /dev/pilot -> ttyUSB1
crw-rw----  1 root uucp 188, 0 Oct 17 09:09 /dev/ttyUSB0
crw-------  1 marc uucp 188, 1 Oct 17 09:09 /dev/ttyUSB1

I added myself to the uucp group.  It doesn't look like this is a 
permissions issue, does it?

I have tried various things, such as using a different USB port on the 
PC, and having jpilot sync to /dev/ttyUSB0 and /dev/ttyUSB1 instead of 
the /dev/pilot symlink.  I've also searched the jpilot mailing list 
archives, and the web in general, and still no solution.  I'm running an 
up to date Centos 4.3 system, pilot-link-0.11.8-8 (from Centos), and 
self-compiled jpilot 0.99.9.

Thanks for any help!
