Hi!

I'm trying udev for the first time and I must say good work!

A sugestion and a question:

- Make udev print a /etc/udev/udev.rules line every time a device is found because default behaviour is too silent and "make DEBUG=true" is too noisy. This would make adding our private/static entries easily.
Something like:

udev[1234]: found device BUS="scsi", SYSFS_model="CD-Writer cd4f", KERNEL="sr0", SYSFS_serial="AAAAAAAA"

This way one can easily make entries for a device with copy+paste, remove a few parameters and adding a few *'s

- I have a USB cd-writer and udev makes /udev/sr0 but it doesn't create /udev/sg0. In the first run I had the hotplug packege from debian but I just installed hotplug-2004_01_05 and it's the same, no sg0 is created.

The kernel detects it:
Jan 14 05:04:40 puma kernel: sr0: scsi3-mmc drive: 20x/20x writer cd/rw xa/form2 cdda pop-up
Jan 14 05:04:40 puma kernel: Attached scsi CD-ROM sr0 at scsi19, channel 0, id 0, lun 0
Jan 14 05:04:40 puma kernel: Attached scsi generic sg0 at scsi19, channel 0, id 0, lun 0, type 5
Jan 14 05:04:40 puma kernel: WARNING: USB Mass Storage data integrity not assured
Jan 14 05:04:40 puma kernel: USB Mass Storage device found at 20

The full udev run, from syslog, is attached.

Do I need a new rule? The log sugests that in that single run udev only cares about sr0, but I can be reading it wrong :) Or sysfs/udev doesn't support scsi_generic yet?

Thanks,
Nuno Silva
