USB pilot-link under Fedora Core 3: /dev/ttyUSBx there but not there


I have pilot-link 0.11.8-8 and several of the higher-level utilities installed on an HP Visualize (similar to a Kayak) running Fedora Core 3 (kernel 2.6.12-1.1372_FC3 #1). Serial port syncing works fine for my Palm IIIe and Kyocera 7135, but I can't get USB syncing to work for either the Kyocera 7135 or my Visor Prism.

udev is installed, so the devices must be dynamically created. I created a file in /etc/udev/rules.d called pilot.rules, containing

BUS="usb" SYSFS{product}="Palm Handheld*" KERNEL="ttyUSB*" SYMLINK="pilot" MODE="666" KERNEL="ttyUSB*" SYMLINK="pilot"

... and restarted the machine.


lsmod shows the following:
Module Size Used by
ohci_hcd 26081 0
visor 20301 0
usbserial 28841 1 visor
.
.
.
So it appears all the necessary modules are loaded.

When I press the hotsync on the Visor cradle, the following messages are logged:


Oct 11 12:41:41 tala kernel: usb 1-1: new full speed USB device using uhci_hcd and address 15
Oct 11 12:41:41 tala kernel: usb 1-1: Handspring Visor / Palm OS: port 1, is for Generic use
Oct 11 12:41:41 tala kernel: usb 1-1: Handspring Visor / Palm OS: port 2, is for HotSync use
Oct 11 12:41:41 tala kernel: usb 1-1: Handspring Visor / Palm OS: Number of ports: 2
Oct 11 12:41:41 tala kernel: visor 1-1:1.0: Handspring Visor / Palm OS converter detected
Oct 11 12:41:41 tala kernel: usb 1-1: Handspring Visor / Palm OS converter now attached to ttyUSB0
Oct 11 12:41:41 tala kernel: usb 1-1: Handspring Visor / Palm OS converter now attached to ttyUSB1
Oct 11 12:41:46 tala udev[10333]: removing device node '/dev/ttyUSB1'
Oct 11 12:41:46 tala kernel: usb 1-1: USB disconnect, address 15
Oct 11 12:41:46 tala kernel: visor ttyUSB0: Handspring Visor / Palm OS converter now disconnected from ttyUSB0
Oct 11 12:41:46 tala kernel: visor ttyUSB1: Handspring Visor / Palm OS converter now disconnected from ttyUSB1
Oct 11 12:41:46 tala kernel: visor 1-1:1.0: device disconnected
Oct 11 12:41:46 tala udev[10330]: removing device node '/dev/ttyUSB0'


... however, the device files /dev/ttyUSB0 and /dev/ttyUSB1 are never actually created, so far as I can tell. Ls says no such files exist, though I'm checking in the interval between when the log says they are created (12:41:41 in the above example) and when they are removed (12:41:46 in the above example). The higher-level Palm tools give similar results.


Any suggestions?

I have exactly the same problem since today.

I have a new treo 650, and set up evolution, gnome-pilot, pilot-link etc. yesterday. Evolution did not work, but the treo connected once (I had to push the sync button before I started pilot-xfer). Today, I upgraded evolution (with yum), and at least it starts up (with a lot of errors), but the sync does not work anymore (no ttyUSB*, though /var/log/messages shows that they are created and that the treo connects).

By the way: I could not login today, after installing all gnome-related rpms to get evolution and gnome-pilot to install. Umcommenting aline in /etc/pam.d/login helped:
# session required pam_loginuid.so

Anyone knows how to handle this? Thanks in advance.

I found out what my problem was. I had my machine configured so that udev was started at boot up. This was obviously changed when I installed some apps to be able to sync my treo.

"/sbin/udevstart" solved the problem, ttyUSB0 & 1 are created in /dev.

Nevertheless, I still cant sync my treo. gpilotd crashes, pilot-xfer gets errors etc ... but connecting works.
