Hi list, Stephen J. Gowdy ask me to forward this to the list. I have still no idea what the problem is but i found an other problem. different tools use different sources for names.
When hotplug mounts the stick it seems to use the "usb-name", creating a dir call /media/<*>Prolific<*>. KDE for example guesses a name based on the "SCSI-name" trying to access /media/<*>EUDAR<*>. therefor interessting error messages :) regards walter - - - - - - - - - - - - - - Original Message - - - - - - - - - - - - - - From: Stephen J.
