I am no computer expert at all, only an ordinary Linux user for 16 years. I noticed that with the introduction of udev a couple of years ago some things stopped working: notably my USB printer: lpq: queue-name:no daemon present. This was not the case when udev was prevented from starting at boot time. Well, you may say 'Why's he clinging on to this old dilapidated lpr thingy?' I won't bore you with the reason why. I could not find a solution on the internet but a hint in the udev documentation made me do this: creating a device-node usblp0 in /lib/udev/devices/ did the trick. I might also mention that even the cd-player device did not work with an ordinary program like alsaplayer for the same reason: /dev/cdrom not being present. [udev created a cdrom1 but it is not used] Remains the question of how to create those device-nodes. I could only do it by booting without udev by doing cp -a /dev/usblp0{cdrom} /lib/udev/devices/ [MAKEDEV refuses to run when udev is on] I won't mention other strange behaviours like udev renaming my only eth card from eth0 to eth1 but that was easy to fix.[pardon me for having it mentioned anyway] Hoping this information has been of mild interest to you but for an ordinary user those common devices not working are a real pain in the ass; I remain, with compliments Yours truly -- Max Euer - Oud Lemiers 18 - NL6295AT Lemiers - T (NL 06)1840 3128 - F (NL 084)716 4118 - E m.euer@zonnet.nl
