Tim,
I think you are confusing sysfs with environment variables. the %E{key}
is used for environment variables. The serial number is a SYSFS
attribute. Try changing %E{serial} to %s{serial} and see if it works.

That didn't work unfortunately, my rules file now looks like this:
KERNEL=="sd*", SUBSYSTEMS=="scsi", SYMLINK+="disknumber-%s{serial}"
Any other ideas?
Tim
It works here, I just made a /etc/udev/rules.d/10-test.rules file with
your above line.
Next I ran 'udevcontrol reload_rules'. I then connected my Kingston USB
drive and /dev/disknumber-5B7A1000021E appeared.
Do you have any other custom rules that are mangling this one?
Cheers,
Mark
It might just be a peculiarity of the USB stick I'm using to test it
then since it's creating a device '/dev/disknumber-' looking like it
can't find the serial number.
I'll try with one of the actual USB hard drives they're using when I
can get access to one next week.
Tim
You can verify that using 'systool'. Try the following command:
systool -b usb -p -v
Find your USB drive in the output, and there should be something like this:
Device = "1-2"
Device path = "/sys/devices/pci0000:00/0000:00:1a.7/usb1/1-2"
bConfigurationValue = "1"
bDeviceClass = "00"
bDeviceProtocol = "00"
bDeviceSubClass = "00"
bMaxPacketSize0 = "64"
bMaxPower = "200mA"
bNumConfigurations = "1"
bNumInterfaces = " 1"
bcdDevice = "0100"
bmAttributes = "80"
configuration =
devnum = "3"
idProduct = "1d00"
idVendor = "13fe"
manufacturer = "Kingston"
maxchild = "0"
product = "DataTraveler 2.0"
serial = "5B7A1000021E"
speed = "480"
uevent = <store method only>
version = " 2.00"
If no serial exists for the device, the "serial =" line will be absent.
Cheers,
Mark
