Hi list: I have had this line in my /etc/udev/rules.d/10-local.rules for a couple years now
<snip> BUS=="usb", KERNEL=="sd?[0-9]", SYSFS{serial}=="DEF10BDD77EE", NAME="%k", SYMLINK+="BackUpDrive" </snip> which matched my external USB harddrive enclosure and name it /dev/BackUpDrive for convenience. I haven't plugged in the drive for a few months now, and udev has been updated from 115-r1 to 124-r1 in the meantime, and the rule doesn't work any more. I think this may have to do with the fact that udevinfo now gives me <snip> looking at device '/bus/usb/devices/1-4:1.0/host24/target24:0:0/24:0:0:0': KERNEL=="24:0:0:0" SUBSYSTEM=="" DRIVER=="sd" ATTR{ioerr_cnt}=="0x1" ATTR{iodone_cnt}=="0x1f" ATTR{iorequest_cnt}=="0x1f" ATTR{iocounterbits}=="32" ATTR{timeout}=="60" ATTR{state}=="running" ATTR{rev}=="0000" ATTR{model}=="0A " ATTR{vendor}=="ST332062" ATTR{scsi_level}=="3" ATTR{type}=="0" ATTR{queue_type}=="none" ATTR{queue_depth}=="1" ATTR{device_blocked}=="0" ATTR{max_sectors}=="240" looking at parent device '/devices/pci0000:00/0000:00:1d.7/usb1/1-4': KERNELS=="1-4" SUBSYSTEMS=="" DRIVERS=="usb" ATTRS{configuration}=="" ATTRS{serial}=="DEF10BDD77EE" ATTRS{product}=="USB2.0 Storage Device" ATTRS{manufacturer}=="Cypress Semiconductor" ATTRS{maxchild}=="0" ATTRS{version}==" 2.00" ATTRS{devnum}=="40" ATTRS{speed}=="480" ATTRS{bMaxPacketSize0}=="64" ATTRS{bNumConfigurations}=="1" ATTRS{bDeviceProtocol}=="00" ATTRS{bDeviceSubClass}=="00" ATTRS{bDeviceClass}=="00" ATTRS{bcdDevice}=="0001" ATTRS{idProduct}=="6830" ATTRS{idVendor}=="04b4" ATTRS{bMaxPower}==" 0mA" ATTRS{bmAttributes}=="c0" ATTRS{bConfigurationValue}=="1" ATTRS{bNumInterfaces}==" 1" </snip> Here's the thing, I am pretty sure that the serial number entry DEF10BDD77EE refers to the drive, and is/was a much better way of matching the actual drive (it is more unique than any of the other bits of information in the udevinfo listing for the sd device), and I would prefer to still match via the serial number in the udev rules. Any suggestions on how I can get my desired behaviour or on how I can debug this? Thanks, Willie -- "`You'd better be prepared for the jump into hyperspace.
