From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.12) Gecko/20080208 Fedora/2.0.0.12-1.fc8 Firefox/2.0.0.12 Description of problem: Suddenly I no longer can see a /dev/ttyUSB* files when I attempt to sync my USB-connected Palm Pilot. I see new /dev/usbdev* files (which seem to change on every sync attempt) and /var/log/messages reports seeing the Palm but no ttyUSB* files are to be found. Version-Release number of selected component (if applicable): usbutils-0.71-2.1, udev-118-1.fc8 How reproducible: Always Steps to Reproduce: 1.Attempt to sync USB-connected Palm Pilot 2. 3. Actual Results: ls -sl /dev/ttyUSB* show no such files Expected Results: /dev/ttyUSB[01] visible Additional info: Without this file (or a substitute) I cannot use my Palm Pilot which is a (very!) mission-critical app for me! This is a huge problem! I have attempted this in KDE and Gnome and attempted a reboot, just in case ... but all with the same result. Did I miss something or is this a new bug?
Could you post output from lshal and udevinfo?
Created attachment 299009 [details] udevinfo --export-db Not sure which modifiers you wanted for the udevinfo command so here is the output of export-db. Please let me know if you would like any additonal information. Thanks, John C
Created attachment 299010 [details] Output of lshal Sorry it took so long to get back to you ... I was out in Denver for a week. Here is the output generated by the lshal command. Please let me know if I can be of any further assitance. Thanks, John C
Did you create these attachments with palm connected? Can you please post output of $ dmesg | tail right after you connect your palm to usb. Jirka
Created attachment 299131 [details] Dmesg, lshal and udevinfo output Ah-ha! ... you didn't mention having the Palm hooked up :-) Here (in one file) I'm attaching the output of dmesg, lshal and udev --export-db with the Palm on it's USB sync station. Thanks, John C
Sorry for the delay, but I didn't have a palm. anyway, I just got one and find a possible solution: 1. log as root 2. $ modprobe visor (module responsible for ttyUSB#) 2. try to sync your palm maybe you'll have to do $ ln -s /dev/ttyUSB0 /dev/pilot to make jpilot work. udev should take care of all of this, but I'm not sure and will try to find some more elegant solution, this is just a quick fix to make it work.. Jirka
So, there seems to be a bug in hal and halinfo which should be fixed soon, in the meantime you can use this solution: 1. create an udev rule (a file): /etc/udev/rules.d/10-visor.rules contaning: BUS=="usb", SYSFS{product}=="Palm Handheld*", KERNEL=="ttyUSB0", SYMLINK +="pilot" 2. edit the file /etc/modprobe.d/blacklist-visor - comment the line visor: #visor 3. restart computer (or just udev) and jpilot should work again. But I've been told there is a bug in visor module so use it on your own responsibility and as soon as the update for hal is released stop using this. Hope this help, Jirka
One more thing - the ttyUSB# nodes will show up after you press the hotsync button.
