Description Noel Carneiro 2005-10-22 20:23:29 UTC

Hi,

every time I have to sync my Handspring Visor (or to any palm device for that
matter - just have a look in the discussion forums!), I had to log as root
(through su) and create a link to /dev/ttyUSB1 (ln -s /dev/ttyUSB1 /dev/pilot)
even though /dev/ttyUSB1 does not exist; and this happens EVERY TIME. The  link
vanishes after each session so, every session I have do create the same link.

This didn't happen with Suse 9.3, since there was a /dev/ttyUSB1. What happened
with Suse 10? Why there is no /dev/ttyUSB1?

This is very, very annoying!!

please attach output of lshal.

Comment 2 Noel Carneiro 2005-10-25 04:16:18 UTC

I sent the output directly to "Danny Kukawka <dkukawka@novell.com>" due to the limit in the number of characters.

Comment 3 Olaf Hering 2005-10-25 05:43:06 UTC

attach the 'hwinfo | gzip -v9 > hwinfo.txt.gz' when the link is gone.
You may want to look at the dmesg output for usb related errors.

Comment 4 Danny Al-Gaaf 2005-10-25 09:26:45 UTC

Not a problem with HAL, maybe with udev.

Comment 5 Hannes Reinecke 2005-10-25 09:43:19 UTC

Danny, care to share your knowledge with us?

just an correction. The first one I sent was done with 9.3 system; this one is with the 10.0 system.

This is the output of "tail -f /var/log/messages" before sync button is pressed.

Comment 12 Hannes Reinecke 2005-10-26 06:56:11 UTC

If I interpret this correctly is just the link /dev/ttyUSB1 -> /dev/pilot missing, correct?
As we're using dynamic device node generation via udev with 10.0, there are several options to fix this:

- Edit the configuration of the affected programs to _not_ use /dev/pilot but  
  rather /dev/ttyUSB1.
- Create the link statically; add the following line to /etc/udev/static_devices.txt:

pilot l /dev/ttyUSB1

- Add a udev rule to create the symlink automatically once ttyUSB1 is created.
E.g.

SUBSYSTEM=="usb", KERNEL=="ttyUSB1", ACTION=="add", SYMLINK+="pilot"

Comment 13 Olaf Hering 2005-10-26 09:21:28 UTC

/dev/pilot was hardcoded in old usb or tty agent.

Comment 14 Hannes Reinecke 2005-10-26 09:58:46 UTC

Kay, should we add it per default?

Comment 15 Petr Ostadal 2005-10-26 10:08:21 UTC

to Comment #12:
affected programs dont'use use only usb devices, but also ttySx, ircomx and so on, therefore we can't change configuration to use /dev/ttyUSB1 instead /dev/pilot.

Comment 16 Kay Sievers 2005-10-26 12:39:38 UTC

Care to add this line:
  BUS=="usb", KERNEL=="ttyUSB*", SYSFS{product}=="Palm Handheld*", SYMLINK+="pilot"

to:
  /etc/udev/rules.d/50-udev.rules

and see if that creates the link for the device?

Sorry, I have no idea how to debug that. I'm closing the bug.
