udev or hotplug problem: fail to create /dev files for USB storage device



Hi, all

I have a USB external disk, which works fine under windows as well as Ubuntu Linux. When I plug it to my debian box (Debian Testing, uptodate, self-made 2.6.13), it does not create the /dev file and I cannot mount it, although it does recognize the virtual SCSI device according to the dmesg. Here is the segment of syslog:

scsi0 : SCSI emulation for USB Mass Storage devices
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
usb-storage: device found at 3
usb-storage: waiting for device to settle before scanning
  Vendor: HITACHI_  Model: DK23EA-30         Rev: 00K4
  Type:   Direct-Access                      ANSI SCSI revision: 00
usb-storage: device scan complete

I also acquired the syslog from Ubuntu system, which created the /dev file accurately:

scsi0 : SCSI emulation for USB Mass Storage devices
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
usb-storage: device found at 3
usb-storage: waiting for device to settle before scanning
  Vendor: HITACHI_  Model: DK23EA-30         Rev: 00K4
  Type:   Direct-Access                      ANSI SCSI revision: 00
usb-storage: device scan complete
SCSI device sda: 58605120 512-byte hdwr sectors (30006 MB)
sda: assuming drive cache: write through
SCSI device sda: 58605120 512-byte hdwr sectors (30006 MB)
sda: assuming drive cache: write through
 /dev/scsi/host0/bus0/target0/lun0:<6>ACPI: AC Adapter [C130] (on-line)
 p1
Attached scsi disk sda at scsi0, channel 0, id 0, lun 0

I suspect that it is the problem of udev or hotplug. Their daemon processes are all there and I am using the original configuration files that come with apt-get/aptitude. Can anybody give me some hints about possible cause of the problem?

Thanks a lot!

Regards,

Eddie
