In the past when devfs was used I never faced problems. Due to the fact that devfs had got obsolete I switched to udev. The problem is, that for some reason /dev/lp0 is disapearing after a reboot(but this is not always, just sometimes) and sometimes I can print, and then for some *&%$ing reason,now it does not work any more, and I have absolutly no clue where to start looking for the bug. All the drivers I need a,re loaded, like usblp, usbcore, the hcd's(ohci, uhci, and ehci) . cups is running and accepting jobs. dmesg is showing this message for the printer when switched on usb 2-1: USB disconnect, address 3 drivers/usb/class/usblp.c: usblp0: removed usb 2-1: new full speed USB device using address 4 drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 4 if 0 alt 0 proto 2 vid 0x04A9 pid 0x106B The command: udevinfo -r -q name -p /sys/class/usb/lp0 gives me: device not found in database One week back when I did this command I got /dev/lp0. This was with Kernel Version 2.6.3. Now that I am running 2.6.4 it seems not to work anymore, for some reason. I recompiled hotplug and udev. The version of udev and hotplug I use are: hotplug: 20040105 udev: 0.23 One last thing to mention: When hotplug is started I get this error: cat: /sys//class/usb/lp0/bNumCofigurations: No such file or directory /etc/hotplug/usb.agent: line 144: [: too many arguments So, if anyone can give me help on this, please do so. Thanks in advance and best regards.
