Hi,

I've got a completely updated (kernel 2.6.11-1.1366_FC4, only standard RH repositories) FC4 install on my Dell C400 laptop (pIII 1.2Ghz, 512m RAM). I have never been able to sync my treo, or even do a simple backup with pilot-xfer.

Everything starts out looking OK - USB works (I use a USB keyboard/mouse most of the time), and when I have initiated the sync on the treo I can see it:

[root@chucky ~]# lsusb
Bus 003 Device 002: ID 0830:0061 Palm, Inc.
Bus 003 Device 001: ID 0000:0000

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

And output from /var/log/messages looks good:

However, pilot-xfer cannot communicate with the device over /dev/ttyUSB0 or /dev/ttyUSB1 - it errors:

[root@chucky ~]# pilot-xfer -b /home/philip/treo -p /dev/ttyUSB1

Listening to port: /dev/ttyUSB1

Please press the HotSync button now...
Error accepting data on /dev/ttyUSB1

Or just hangs (on ttyUSB0). Eventually the Treo times out and disconnects thusly:
May 31 13:17:48 chucky kernel: usb 3-2: USB disconnect, address 2
May 31 13:17:48 chucky kernel: visor ttyUSB0: Handspring Visor / Palm OS converter now disconnected from ttyUSB0

May 31 13:17:48 chucky kernel: visor 3-2:1.0: device disconnected

Attempting to do this via gpilot-applet results in gpilotd repeadedly crashing out underneath it, but that's a whole otehr story.

any ideas?
