empty BUS name

empty BUS name

[Alessandro Zummo]

 Hello,

  this is the output of udevinfo on my usb printer:

device '/sys/class/usb/lp0' has major:minor 180:0
  looking at class device '/sys/class/usb/lp0':
    SYSFS{dev}="180:0"

follow the class device's "device"
  looking at the device chain at '/sys/devices/pci0000:00/0000:00:1f.2/usb1/1-1/1-1.2/1-1.2:1.0':
    BUS=""
    ID="1-1.2:1.0"
    SYSFS{bAlternateSetting}=" 0"

 [..]

  looking at the device chain at '/sys/devices/pci0000:00/0000:00:1f.2/usb1/1-1/1-1.2':
    BUS=""
    ID="1-1.2"
    SYSFS{bConfigurationValue}="1"
    SYSFS{bDeviceClass}="00"
    SYSFS{bDeviceProtocol}="00"
    SYSFS{bDeviceSubClass}="00"
    SYSFS{bMaxPower}="  0mA"
    SYSFS{bNumConfigurations}="1"
    SYSFS{bNumInterfaces}=" 1"
    SYSFS{bcdDevice}="0100"
    SYSFS{bmAttributes}="c0"
    SYSFS{detach_state}="0"
    SYSFS{devnum}="3"
    SYSFS{idProduct}="300c"
    SYSFS{idVendor}="04e8"
    SYSFS{manufacturer}="Samsung Electronics Co., Ltd."
    SYSFS{maxchild}="0"
    SYSFS{product}="Samsung Laser Printer ML-1200 Series"
    SYSFS{speed}="12"
    SYSFS{version}=" 1.10"

 shouldn't BUS="" be BUS="usb" ?

 some udev rules are not triggered due to this mismatch..
 tried with kernels 2.6.10-bk5 and bk12

What does:
  ls -l /sys/bus/usb/devices/

print?


It works on my box:
  [kay@pim ~]$ udevinfo -a -p/sys/class/usb/lp0

  device '/sys/class/usb/lp0' has major:minor 180:0
    looking at class device '/sys/class/usb/lp0':
      SYSFS{dev}="180:0"

  follow the class device's "device"
    looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1.3/3-1.3:1.0':
      BUS="usb"
      ID="3-1.3:1.0"
      SYSFS{bAlternateSetting}=" 0"
      SYSFS{bInterfaceClass}="07"
      SYSFS{bInterfaceNumber}="00"

ls -l /sys/bus/usb/devices/
ls: /sys/bus/usb/devices/: Not a directory

 ARGH!!! That was the problem.. 
 
 somehow I ended with this line on my fstab

 none            /sys/bus/usb    usbfs   devmode\x0666            0       0

 Thank you very much! I will accept any penality for
 such a fault! :D
